Master Evans is a great role model. My daughter looks up to her so much. She's become an icon in our household. The skills and values that kids learn here will get them ahead in life. read more

Seems I'm right there with everyone else who has reviewed this place. I did not send my kids here when they were kids. Just because I had no idea it existed. If you have a kid, don't hesitate for a nanosecond, just bring them. If you're older, like 61 and feeling able bodied, dont hesitate for a nanosecond! This space and place is welcoming and inviting and really sort of defies definition. So. Check it out. See for yourself. read more

Our 8 year-old son has been a member of Quantum Martial Arts for 10 months now, and we couldn't be happier with the program. Master Evans is amazing with the kids, and it's great to see how much love and respect her students have for her. She really takes time to get to know each kid individually and is able to draw even the most shy ones out of their shell. Our son was never very into team sports and disliked the competitive environment that sometimes goes along with them. That said, martial arts has been a wonderful outlet for him, and his confidence and self-esteem have never been better. He went from going once a week, to now going 3 times a week because he loves it so much. Master Evans and her staff have gone above and beyond to help my son and other kids like him feel part of a real community, where they're learning valuable life lessons beyond just karate skills. In addition to adult and kids' classes there are many fun community events like concerts, talent shows, a kids' sleep over party, and now they are offering a summer camp for the first time. We hope to be part of this wonderful community for a long time! read more

Quantum Martial Arts - Belt ceremony - Martial Arts Near Me - San Francisco, California

I first took my daughter to Quantum a couple of years ago when she was 7yo and was having some issues at school. I was looking for a place where she would work through some of the relationships issues she was having. Little a knew we had actually found a second home, for her and for myself. The Quantum dojo is a place to learn martial arts and also a place to learn about yourself, supported by a caring community and the dedicated stewardship of Master Evans. After my daughter had been practicing for about 1.5 years I joined the classes myself. Now it is a "thing" we do as a family, it is a place that we both challenge ourselves and have that shared experience to bond us. The classes vary in size and challenge level, they are taught by the different instructors and by master Evans, but they always leave me with a feeling of gratitude and physical satisfaction for being there! read more

Rachel is a great teacher ! My daughter loves the class and commit to it so now two of her friends joined the class and I think everybody is doing great! read more

I have been training at Quantum since 2011 and I am now a blue belt. Words can't describe how I have woven martial arts into my daily life thanks to Master Rachael Evan, the Quantum curriculum/program she has developed, and the students who study/experience it alongside me. The sum is truly greater than all the parts. The confidence I have found learning how to do a tornado kick, hook punch into a back fist, and take down an opponent onto the mat has spilled over into my personal life, just as one would expect of anyone who commits themselves to a discipline. The cliches are true: I get more out of my day, I bring calm to business meetings, and give more back to the community. Martial Arts is not for everybody. Maybe what you are looking for is learning to play the harp, speak Chinese, or write the next great sci-fi novel. But come in and see what were all about. Stay for one class, stay for two weeks, stay for one year, stay for more. Learning how to learn has an amazing return of investment. UPDATE 5/2016: In the past year we have renovated the dojo and it's now sparkling white. I am now teaching basics class once a month on Monday nights. I am learning more about Chi Sau, Push Hands, and grappling. My body is physically changing to be able to meet the demands of these new techniques and I am relearning how to walk, stand, and sit. What I am most proud of is our diverse community of learners. The more kinds of people we have in the dojo, the deeper my practice becomes. read more

I highly recommend Quantum Martial Arts. Master Rachel Evans is great and so are the other instructors. This is such a formative time in my eleven year old daughter's life - I am so glad she has found this new family. On another note, they are expanding and doubling their space in an adjoining room - I can't wait to see the finished space. read more

We loved all the teachers and the community they create! Our kids love the classes, they teach disciple in a warm and respectful manner, great for children, and parents :) read more

I joined Quantum Martial Arts a couple months ago, and I immediately felt right at home. Master Evans teaches a martial arts style rooted in taekwondo, and which incorporates elements of other martial arts traditions. She brings incredible dedication, energy, and integrity to her teaching. She loves what she does, and it shows. I would describe Master Evans's teaching style with both adults and kids as "firm but fun" -- she works hard to make the classes rewarding for students of all ages, while modeling (and expecting) both courtesy and respect. Her assistant instructors are likewise terrific, and clearly work to embody the same virtues themselves. The school is organized as a non-profit, dedicated to bringing the benefit of martial arts study and practice to the general public. The adult membership fee and monthly dues are quite modest, and are offered on a sliding scale. The Quantum community is friendly, inclusive, and supportive. Everyone at Quantum is expected to serve as both a student and a teacher, to whatever degree they're able. The classes are very physically and mentally demanding, but you get the feeling right away that everyone else in the school wants to help you learn and succeed. In short, if you're interested in taking up a martial arts discipline in an richly supportive environment, I can't recommend Quantum enough. read more

My son started with martial arts a few years back when he was 6. He is not the most focused kid and is not into teams sports - so martial arts seemed a good option to at the time. We started at a different school and I saw him lose all interest after a year. I didn't want him to give up on Martial Arts and explored a few different schools. I came by Quantum and immediately fell in love with their bright, open space. For the younger kids, they set up a really fun obstacle course for warm ups - which was all the motivation my son needed. He has now been with Quantum for a couple of years, and not only is he interested in Martial Arts again, he doesn't want to miss a class. Master Rachel is a wonderful role model for him and for our community. She is tireless and so generous with her time. Everyone who works or volunteers at the Dojo are passionate about what they do and give 100%. There is a great sense of community at the Dojo. I would say the only issue with the space is parking - there is only street parking available - and that is hit or miss. But if you are within walking/bus distance and you're considering a martial arts school, you simply must give Quantum a try! read more

If the Universe set out purposefully to create a martial arts instructor, it would create Master Evans. She's the lively, intense, irreverent and brilliantly positive founder of Quantum Martial Arts, and quite possibly the most talented instructor I have ever met. In some schools, punching in the right direction is good enough. Here, if you are not totally in alignment and flowing with the right blend of speed, tension, and relaxation, Master Evans knows. And she knows how to correct you so that it becomes effortless. Master Evans engineered Quantum as a blend of styles, and she understands it all so thoroughly that if you ask her why this stance or move is exactly so, she can tell you. She doesn't just love Quantum, she lives and breaths and *is* martial arts. And she gets giggly with excitement at the prospect of passing it on to you. The community she's created is just as quirky and intense. Always welcoming, always friendly, always positive; energetic, cheerful, and occasionally silly, yet still serious and focused and grounded in reality. If you're at all considering martial arts, drop in for a free class. Whatever level you're at, Quantum will welcome you as you are, and take you to the next level. The first half of class is yoga stretches and callisthenics, the second martial arts practice. Whether you're looking for a fun workout regime or a strong martial arts school, you'll find it here. read more

Intense, yet unpretentious. I came to Quantum after trying 2 other dojos. Master Evans has built not just a martial arts school, but a community of supportive folks who've all come together with only one goal: to become better human beings. Each class begins with an intense calisthenics and stretching "warm up". It's some kind of a cross between yoga and marine boot camp. Then, once you're completely exhausted and have nothing left, class begins. Master Evans is incredibly demanding, while at the same time being infinitely patient. She offers guidance without reproach. Above all, despite her own mastery of martial arts (and life in general), she doesn't take herself too seriously. If you're looking for what may be the best workout of your life, in body, mind, and spirit, give Quantum a try; you won't regret it. read more

My darling daughter has been attending Quantum Martial Arts for about three months and I cannot even tell you how great it is for our whole family. Master Rachael is always super great with all of the kids - funny, encouraging and empowering. At the end of each class they circle up and have a little talk about one of the tenants of martial arts. I had such a proud moment when my little girl put up her hand and correctly recited the definition of perseverance: "always try your best" Of course, as a human being and a young one at that, my little one sometimes puts up a little resistance to attending class, and I'll just let her know that she can share her thoughts and feelings with Master Rachael or Ms. Popovich and then once we get to the dojo, somehow all that resistance falls away and she suits up and has a great time! Now that she has earned the yellow stripe on her belt, she is totally hooked! Thanks, for being AWESOME Quantum! read more

I have been attending Quantum for the better part of 2 months now and have loved every minute of it. Master Evans is an excellent teacher, incredibly patient, and more than happy to help. She ensures that everyone is giving it their best, and she pushes you to your limits. The students in the class are all great people. Super friendly, and I felt welcome into Quantum on the first day. Everyone wants to help and there is a real atmosphere of learning, self-improvement, and camaraderie. If you have an interest in not only the martial arts, but improving yourself physically and spiritually, come to Quantum! There is plenty of room for you read more

I attended Quantum for the first time this past Saturday with my girlfriend. We're an LGBT couple and were looking for a friendly school where we could train together. Before this past weekend, I'd never attended a "hard" martial arts school or class. The only related background I have is in yoga (20 years), meditation (10+ yrs), Asian medicine philosophy (5 yrs), and a few (medical) qigong classes. I wasn't sure how my past experiences would help with my first Karate class here but it blended quite well and did not feel like a giant stretch. I'm sure that part of this had to do with the teachers here and the overall school philosophy. I would encourage those with similar backgrounds who may have been resisting trying a hard external martial arts style to check this out. I am a petite woman who sometimes serves as a security volunteer for large events of 2-3K people - mostly when traveling spiritual teachers visit the San Francisco Bay Area. This sometimes requires driving, close protection and even interfacing with security teams from multiple countries state departments - you know, those people who actually know what they're doing. For myself, I am merely untrained "cannon fodder" that isn't afraid to die. However, I am no longer single, and my girlfriend wants me to come back home in one piece after debriefings. To give you an idea of what I like in a style of teacher...if I had any pick I would probably chose to train with "Guide" (her preference of title) Eva Wong but she's based out of state and rarely visits my area or ever does classes for newbies like me. She is a lineage carrier of Xiantianwujimen which is a Taoist hermit lineage whose teachings "leave no trace"...what I'm getting to here is that naturally in the true spirit of that style...it's hard to even find the woman for teachings. :) In the meantime, it looks pretty certain that Master Rachel Evans at Quantum could greatly help anyone improve the skill of their gross body so that it matches up better with their fearless spirit. My girlfriend and I will be back to visit and will probably become members. Also, note: This school has upgraded to nice white padded flooring now which is not visible yet in most of the pics here on Yelp. read more

Quantum Martial Arts is quite simply: awesome. A lot of fun, a great workout, and this school is run by a group of really welcoming, friendly people with two amazing teachers. They focus on personal and spiritual growth not competitions and winning, so it's all about learning the art for arts sake. I've been training in Quantum for about five months only, but am completely hooked. I'd never done any sort of martial arts before, came from a background of yoga, but in just a few months I've already earned a yellow belt and feel so healthy and at peace. Even if you've never done any karate before, you will be shown everything with patience and enthusiasm. If you have studied some sort of martial art you will probably be pleasantly surprised by the unique style that blends all sorts of disciplines. The current space is gorgeous at Mission Yoga. You can get into the building via Mission or 20th street, up the stairs to the third floor. It's right on the corner, diagonally across from Ritmo! read more

Completely stiff and out of shape, I arrived at Quantum with no experience but a hope to fulfill a lifelong desire to learn martial arts. Three months later, I'm amazed by the strength, flexibility, endurance and skill I've developed in throwing kicks etc. Master Evans is an intense and dedicated master who has developed a martial arts curriculum that combines part yoga/strength training along with the mixed martial arts. As a person who was new to town and looking to start an exercise training regime I could continue with for years, I find the environment to be a good match for my personality and I hope to continue for years. Quantum is intense but has given me opportunities to make new friends while combining strength, flexibility and martial arts training. With an open environment to all beginners I encourage those interested to try it out! But don't forget your water and be ready for a tough first few sessions! read more

I've been going to Quantum Martial Arts for a month now and classes are my favorite part of the week. I had no previous martial arts or yoga experience and before coming to Quantum and it was no problem. The instructors are excellent teachers and are very welcoming and patient. The quality of instruction is great and both the teachers and students create a very supportive atmosphere. The workout is amazing. I really feel like I'm developing strength and flexibility, and learning a bit of philosophy too. The first month is free, so you should definitely check it out! read more

I've been a student at Quantum Martial Arts for a little over 2 years now. I'd been looking for an activity to help me get in to better physical health and had tried other Martial Arts schools around the city. I found many of them to be have a very aggressive "MMA" attitude to them. It was all about competition and being the best and to "Beat your opponent in to the ground". Other dojo's approached teaching Martial Arts from a point of fear. The attitude was that you were a victim waiting to happen and you needed to learn how to defend yourself. This was not an appealing way to learn MA. Master Evans approaches teaching from a completely different angle. It's all about learning to be in the moment, not worrying about the past or future. I'm not doing her philosophy justice here and you must speak to her in person to fully understand. The dojo she and her Senior Student Mark Currenton have created here is free of the BS competition attitude and victim shtick you see at other Dojo's. The space and the students that come to Quantum have a very good and unique vibe. The classes begin with intense warm up calisthenics that focus on shaping up your core muscles while the classes themselves involve drills with sparring, Chi Sau and forms practice for the upper levels. The first few weeks are physically a killer but after you get used to them, you begin to see many positive changes both physically and in your attitude as well. Quantum is not for everyone, but whats great about it, if it's for you, it will speak to you the first time you take a class. read more

Quantum is the martial arts school for those of us who love to dance, do yoga, look people in the eye and smile. The style is serious and it's tremendously hard work physically, but that hard works brings you to a place of grounding and calm. I've been studying Quantum for five years. I'm taking my own sweet time to rise up the belt ranks -- this is not a school where you are on a schedule to get this, that and the other colour of belt. As you do, however, the depth of the style opens up from more traditional Taekwondo to include elements Jujutsu, Wing Chun, Aikido and even Tai Chi. Classes take the form of around 45 minutes of calisthenics and stretching to strengthen the body and warm up, then another 45 minutes plus of drills and techniques. Once or twice a week we practice forms (a set of moves), one-steps (formal responses to an attack), advanced techniques and sparring. Sparring at Quantum is non-competitive, testing your physical limits and engaging in a kind of martial dance with your opponent. No special clothes are needed to get started, just some sweatpants, and you can just show up at a class. The first month is free, and after that dues are a mere $50/month. We're a pretty small school right now (the Seattle school numbers 100+) and very welcoming to new folks. read more

I love this place. We chose Quantum after going to a few different places to tour schools for our kiddo . The atmosphere is welcoming it's community based and the staff is amazing! Great for kids and adults. If you give it a try I doubt you'd be disappointed. read more

"We Love Quantum community and the space that offers. Our son has had the opportunity to know himself and to grow not only physically but also to connect with his internal force so in that way been able to learn that the physical and mental limits are conquered by our internal focus. Thanks so much to the marvelous Quantum community for supporting our son, since he was a kid, to become a Leader in his own life and community. -Loreto y Juan, parents of a Quantum Teen read more

I have never done martial arts before however, with a bit of self prodding i FINALLY got myself to a class and now I'm hooked. It is a serious workout without feeling like one.. and coming from someone who's idea of working out is walking to the coffee shop...its a HUGE hit. The workout targets all muscles however focuses on spirituality, focus and mind....like yoga but more personal. The instructor is SUPER awesome and gives very individualized attention for even the most uncoordinated (me). The instruction is about strength and thinking versus just kicking ass (that does come in later)... I would highly suggest it to anyone who is looking for a diverse, super upbeat, non-competitive environment to learn something REALLY cool... plus think of all the bar tricks! Its Monday and Thursday 730-930 and sat 2-4.. read more

I have been a part of this amazing group of martial artists for almost two years. Master Evans and Amy have created an environment of growth, friendship, trust and becoming the best person you can be by pushing your boundaries both mentally and physically. The beauty of Quantum is that it is a non-profit founded in the passion Master Evans has for the teaching of her art. The other reviews have it spot on. From the first day I stumbled through the doors of this dojo I knew this was what I needed. read more

I joined Quantum about 2 years ago because i was interested into learning Martial Arts and new skills, but I def stayed for the community and for what Master Evans brought into my life. The teaching is amazing, and the support and care you receive from everyone, from students to teachers, is really what makes it an unique and amazing place. This is not a place that will judge or ignore you if you are a beginner, on the contrary everyone takes the time to make you feel good and included in the community. Class can be hard but you will definitely see yourself improving and you'll learn a lot. read more

I've been with the Seattle school for 8 years now and I love it. It has always had a diverse and open community. The training is tough and practical but also has a equal focus on the "Art" in martial arts, so I feel it provides a space for people to train at different levels and always be challenged. I've been down to the SF School twice now and I can all ready feel the positive energy and hard work they are doing there. If your in SF and looking for a place to learn Martial Arts, go in and talk to Master Evans and take a class. I bet it wont be your only one. read more

Integrate Yoga, Boxing, Boot Camp, Weight Lifting and Self-Defense and you get Quantum. This is one of the best places to train and learn martial arts the Master (Lead Instructor) of the school is warm, welcoming, highly intelligent and a great instructor. You will be turned into tip-top shape and given a mental refresher in the process. Highly Recommended to beginners and advanced Martial arts students. You get exposure to various styles from Tae Kwon Do to Wing Chun Kung Fu to Hapkido and Jujitsu Mixed Martial Arts without the macho bravado. Awesome! Queer Friendly! read more

I have taken 2 classes here so far and both times (even when I am in shape) I can barely walk! My stomach muscles are actually very sore to the point that it hurts to cough. This is a great intimate studio where the students all know each other, are friendly and even hang out outside of class. The instructors know their stuff and push you to the limit. I am currently deciding on a place to set my roots down in, but this is a top contender. read more

The new San Fransisco dojo provides the Mission district with a martial arts treat. Rachel Evans is the "real deal", providing expert instruction developed in over 20 years of Martial Arts experience. A Quantum session combines hard work with laughs, intensity and kindness, patience and a constant encouragement to put out your best effort. There's been many a workout I've come in fatigued, trained hard in class, and come out with a bounty of energy. A typical Quantum session combines plenty of stretching, core/abdominal work, static stance work, and development of movement, strikes and blocks. The end result is a wonderful workout that improves flexibility, core strength, leg strength, balance, and develops and improves kinesthetic skills to a high degree. I'm giving the dojo 4 out of 5 stars because no dojo fits everyone. Sessions are relatively long (90 minutes), and grappling skills are reserved for advanced students. In addition, students with macho attitudes will quickly find themselves unwelcome. But if you are in the area and looking to either begin or find a new martial arts school, you owe it to yourself to try out a general class or (if you are feeling frisky) a basics class, because training in the Quantum style can be an extremely rewarding experience. (Disclosure - Quantum Student, Seattle, 2003-2007 and looking to return in 2008) read more

This is such a great place for kids to learn martial arts in the mission. The teacher really know how to work well with kids. It's really helped my 6 year old son improve his overall discipline at home and in school. Also the cost does not break the bank. read more

I've been missing my fix of martial arts for over 12 years; had to quit because it was so darn expensive! I came across Quantum on Yelp and now I'm returning the favor. After only 1 month of attending class ~1/week, I'm hooked. Master Evans and her crew have welcomed me with open arms and I'm so excited to officially join this amazing community. Come! Join us! read more

I am a new student at the dojo, and have to say that Master Evans seems to be reaching me. I can't say I knew what I was looking for when I got there, or that I found it when I did.. but a friend suggested I go check it out... The classes are small, and the pretense is none. Students regularly introduce themselves to me before and after class. And nobody is perfect. Nobody can do all the exercises perfectly. But the example is there, and you are welcome to do your best. One thing I asked her tonight was, "why do we bow when we first enter the room?" She started to say it was about a lot of different things but then paused and summed it up with, "it means you are entering this room specifically to do this.. and you are leaving everything else out there," and that made a lot of sense to me. Last week she marked me by saying that self-defense implies a certain type of victimhood (because all defenders are victims of an attack) "..and I would just rather know exactly what's going on around me," meaning she would know how to avoid/counter/block/whatever any move anyone else is going to make. And just with that mindset, she has already leveled the playing field. There is a certain down-to-earth realism there. Yes, it is like a cross between yoga and mixed martial arts - which is great. But it's also personal, it's intimate, and Master Evans has been doing this a long, long time. The breadth of her experience is a time-wrapped gift for you. I'm not sure exactly what I'll be getting out of this in the end. But I can tell you I'm richer for the experience so far. I'll be seeing you again there next week. -kamsamnida. read more

My son Jaja has been doing karate at Quantum martial arts for nearly two years now. It has been such an amazing experience for him and I am so absolutely thankful that we have the support and incredible opportunity that it offers him. Since he began, I have seen his strength and confidence grow extremely. It's wonderful to know he has a place he considers a second home, a place he truly belongs, is accepted and can thrive. I have never seen him come from class and not be completely excited and filled with joy. Its amazing to watch his self-confidence and knowledge of self defense grow. I always knew that if I had a kid I would want them to know martial arts, and was so thankful to find Quantum! Master Rachael Evans is a true shining Light and has such a deep understanding of sharing her art form so gracefully. I am filled with deep respect and appreciation for her ability to work with children. She is a great role model and keeps instruction and discipline tight but adds a strong element of fun and positivity. The other part of the awesome environment of Quantum is the assistants she chooses. They are all kind, supportive and very present and focused. I feel this is important for the class, as they add so much. read more

If you are looking for a Dojo, come here! Do not wait. My experience with martial arts before Quantum consisted of some Billy Blanks tapes in college. Yes, people, we are talking VHS. As a near complete beginner, I felt comfortable at the dojo immediately. Master Rachael Evans is, undoubtedly, a gifted, generous teacher. She can read the body like a cartographer reads the landscape or a sea-captain gauges the movement of waves and I feel lucky to be on her ship. The woman could teach karate to a cardboard box, but she thankfully does not have to because Quantum comes with students who are skilled, passionate, and engaged. I have learned from each of them. I would highly recommend Quantum for the experienced student as well. It is a responsible, challenging way of training. The technique is one developed by Master Evans and one she continues to evolve, based mostly in Tae Kwon Do and Kung Fu. The warm up is about an hour long and consists of modified yoga poses which complement and anticipate the karate, and many, many crunches (triple digits!), push-ups (you will grow to like them!), and wrist stretches. Then, everyone gets into lines and we bust some moves. So fun. Who knew happiness could come on the end of a jab-reverse-punch to the solar plexus? (no contact for beginners, of course). And somewhere along the line, in the midst of your round kicks and downward blocks and shuffles and jabs, a curious thing happens. You start to sense an energy running through you, invisible, but plainly felt. And it sticks around while you do your laundry and pay your bills and fall in and out of love and do your work and scrub the shower. I know it sounds all Star Wars and New Age-y, but I swear it's a thing, a verifiable effect of the intricacies of the body channeling the tangible force of gravity within community. Michael S. put it well in his review below - you can experience that kind of vitality by playing the harp or learning a language, but maybe come practice karate first. You might just be taken by surprise. And if you are not interested in the metaphysical aspects behind the simple truths of movement and gravity, that is just fine. Bikini season is upon us. Come do your crunches and learn your karate. You will get an incredible workout and look better in your jeans, and no one will want to mess with you. But in my observation, those drawn to Quantum are there for something more. Quantum also offers a wonderful kids program for ages 6-12. Master Evans has literally decades of experience teaching little ones and brings her knowledge and her own child-like exuberance to the task. Oh, and did I mention that it is affordable and the first two weeks are free...? read more

I can't say enough wonderful things about Master Evans, Mr. Curenton and their school. My wife, a longtime yoga devotee, and I had been trying for some time to find a fitness and wellness regime that suited both of our views on life. After several failed attempts at different yoga schools and gyms, we finally found something that stuck in Quantum (which, for the record, we found through Yelp). The first thing that struck me was how welcoming Mr. Curenton was, and how open and friendly the entire experience of our first class was. Master Evans took us aside after the initial workout, taught us some very basics and told us about her approach to the martial arts. Her joy for life was apparent, honest and infectious, and her attitude of art before martial was evident. This is not a school for those who wish only to kick ass (although she could most certainly kick yours!). I'll be terribly honest here and let the uninitiated know that the workouts are brutal. In a good way. I didn't think I'd survive the first one, and that thought was tripled by the pain I felt a couple days later. I'm happy to report, though, that as a still relatively new student, I now get through the calisthenics (mostly), and no longer feel pain, but strength and flexibility, following. It's wonderful beyond description. The remainder of the initial classes are focused on the different stances, blocks, punches and kicks of Quantum. Once again, Mr. Curenton and Master Evans shine in their absolute patience, humor and wonderful teaching methods. They engage the entire class, but leave no one wanting for personal attention or correction. Obviously, more advanced classes are available before or after, depending on the day. In short, I cannot recommend this class highly enough. The basic classes are free, until you decide to contribute to their nonprofit (you will), and the monthly fee thereafter is well worth what you get out of it. The instructors are flipping incredible, and know how to balance teaching, correction, humor and discipline. Let me say that again. Flipping incredible. Show up for one class. It's free, for freaks sake. If you're anything like me (or my wife or friends who've since adopted), you will be back and happy to let Master Evans whip you into shape with a smile (while Michael Jackson plays on her iPod). read more

I LOVE LOVE LOVE Quantum!!!!! Master Rachael is amazing! My daughter has learned so much self defense and especially how to focus more. I just can't say enough about Quantum. It's a real family atmosphere there. read more

I've tried out practically every martial arts studio in the city. Time and time again I've encountered a room full of agro weirdos battling the ghosts of their past and Masters enabling this. GET ME OUTTA THERE. You won't get that with Quantum. Quantum surpasses my experiences with each and every one of these studios by LEAGUES. With Quantum, you'll experience Master Evans's thorough knowledge and incredibly effective and attentive teaching stylings, and a supportive community who checks their egos at the door, who are ready to learn and be challenged. Let me tell you my endorphine buzz lasts for DAYS after each class. 3 hours fly by and I feel more confident, flexible, grounded and aware of my body. I've been working with Quantum for only a few months and I can touch the palms of my hands to the ground, I got abs like WOAH, I can comfortably surf the MUNI, my back tension has completely dissolved, I have more energy, I'm more relaxed... I could go on, but come and try the class to experience this for yourself! read more

I second what all of the other glowing reviews have mentioned. Not only will you become a martial artist well versed in a variety of styles, you'll become a better person in the process. read more

I moved to San Francisco and immediately set about investigating the best way to pursue a practice that would not only challenge me physically, but also contain a component that furthered my contemplative and meditative goals. Quantum Martial Arts is where I tried after some careful searching, and wouldn't you know it, it had everything I wanted. Master Evans is everything the other say and more. She is wonderful to talk to, is never disrespectful, and is always excited to start working; all that she asks of you is the same. It is obvious that she loves the school and is dedicated to helping every student find something in it that furthers them either physically or emotionally down the path they have chosen. It is also immediately apparent that the students are there because they pick up on the rarity of such a community, especially in a world which is dominated by a recent trend in training for direct application such as MMA. At Quantum, we do spar, and in doing so you get to know those who are similarly taking time out of their day to come work, to improve their bodies, and to challenge themselves with a practice that is as much about working your body hard as it is about realizing how to push yourself mentally. My only wish is that I was better at pushing myself to go to class, to put aside all of the other little things begging for my time - that's how good this class is and how good I feel every time I leave. I am very excited to continue attending and to grow my skills under the tutelage of Master Evans and the senior students. Best yet, the door is always open for new students and new friends. read more

Hello, Let me first say that I've been attending Quantum for the better part of three to four years. I also practiced other martial arts before come to Quantum. That being said, Quantum has radically changed my life, bringing me in touch with inner peace, clarity, and a new drive to better myself. I love Master Evans and all the other students, but make no mistake, it is You who does the crunches, You who shows up to class, and You who will change your life. Quantum will present you with tools not just to be fit in body and mind, but to reshape the world and how you fit into it. For anyone who feels lost, for anyone who wants to feel safer walking down the street, or for anyone who is looking to challenge themselves, I can't recommend Quantum more. The community is very welcoming and accepting. Expect to see a brand new Dojo soon, so come take advantage of the first free month and see how you like it! read more
