Jitsu Has Truly Transformed My Daughter's Confidence Choosing Jitsu for my daughter was intentional. I wanted her to learn how to protect herself -- and if needed, to protect her little sister and her friends. I wanted her to grow up knowing she was strong, aware, and capable. What I didn't realize was how much more this journey would give her. When she first joined, she was shy and uncertain, but everything changed once she stepped onto the mat and into a community that believed in her. Having her best friend there made the experience even more special. They pushed each other, laughed through tough drills, and grew side by side in ways only true teammates can. Now it's been two years and counting, and she's still not sick of it -- not even close. If anything, she loves it more than when she started. That alone tells you they're doing something completely right. One of the biggest takeaways she's held onto is: "Never cry on the mat." And she takes it very literally -- but honestly, it's not a bad thing. For her, it means fight harder, stay focused, and don't give up. We get it... but let's be real, moms are absolutely allowed to cry on the sidelines. As a mom, it still scares me watching her train and compete -- that feeling never truly goes away. But her confidence has grown so strong that she's now the one asking me to sign her up for competitions. Seeing her walk onto the mat with purpose and pride is something I never imagined two years ago. I have to give so much credit to Jorge, Coach Chris, and Coach Brandon. They prepare her for every competition with patience, discipline, and unwavering belief in her. They've helped shape her into a girl who isn't afraid to push herself, challenge herself, and trust her own strength. Because of them, my heart is at ease a little more each time she competes. Jitsu didn't just teach her self-defense -- it opened a whole new world inside her. One filled with courage, growth, friendship, and confidence. Watching her transform has been one of the greatest gifts, and for that, I am endlessly grateful. read more

I've had the opportunity to train here since early this January 2025, coming from other gyms and it's always a good time here. The teaching of the night class by Coach Chris really gets you to grasp the concept and techniques to learn at all levels, especially as a white belt. Highly recommended to my friends and coworkers to hit the matts!! read more

Alere Jiu Jitsu Academy - Brazilian Jiu-jitsu Near Me - Castro Valley, California

Very welcoming and high quality BJJ academy! I joined after taking over my son's membership in 2023 and never stopped coming. As a woman on the shorter side, I appreciate how most of the guys are focused on using technique instead of strength during rolls. Additionally, the fellow women students are very supportive and great to network with! When it's time for upcoming competitions, the coaches ensure the level of instruction suits both the competitors and hobbyists. This is a wonderful academy for the whole family to train. read more

Alere Jiu Jitsu Academy - Brazilian Jiu-jitsu Near Me - Castro Valley, California

My now 10-year-old son started training at this gym two years ago. We have had such an amazing experience with them. The coaches know how to train their students with just the right balance of discipline, strictness, and kindness. My son loves the classes and looks forward to going everyday; I have seen such a positive impact jiu-jitsu has had on my his state of mind, confidence, and fitness. The quality of training here is excellent; my son competes in the Jiu-Jitsu World League, competitions, and he won first place in his division at the last tournament, all thanks to his amazing coaches and how they prepared him. I now witness him choosing to do hard things because he has learned the value of hard work and discipline and loves that feeling of accomplishment when he gains his reward. The price of the classes is super reasonable, and we love the flexibility of being able to come to any class on any weekday without having to reserve or commit to specific days ahead of time. The owners are not all about making $$ with belt promotions and all of that--you can tell they truly just care about nurturing and supporting their students in this art, truly living up to their name "Alere." Super grateful we found this gym. read more

I have been training at Warrior Jiu Jitsu Castro Valley for about 6 months, with prior experiences (very much on and off) for about 8 years and at four different gyms; switching due to relocation the first three times, and this last time due to life events and having Warrior's schedule being one of the only local gyms that I was able to make work, in order to get back on the mats. I can only speak to the morning classes as I have yet to attend an evening class. I knew the type of gym I wanted for the type of training that I do: Safe, fun, technical, and one that did not have funnels to extract every dollar out of you. There are no paid belt tests. There are no required branded uniforms. There are no set franchise curriculum or contracts. Warrior Jiu Jitsu nurtures world class, medal-winning, athletes in a relaxed and welcoming environment for people of all ages, as well to those who train for different reasons. The classes are diverse of age, gender, ethnicity, of varying belt ranks, which is a big green flag. Bonus: plenty of parking read more

What first brought me to Alere in June of 2025 was the glowing reviews on yelp. It seemed to be exactly what i was looking for as someone who wanted a hobby and a community (since I'm from Ohio and moved to California) my experience has been nothing short of amazing. The people, the coaching and the energy are all amazing. I have enjoyed everything. I have even officially converted to social media algorithms to jiu jitsu and cats. The atmosphere is one of teaching and learning. I leave every class more confident than the last and feeling like i have so much more to learn and it keeps me excited. Highly recommend. You might just find a new passion and a new friend group! read more

Alere Jiu Jitsu is a true gem of an academy in the East Bay. My kids and I have been training here for three years, and the quality of instruction and community is unmatched. The coaches are top-notch--extremely knowledgeable, hands-on, and committed to each student's goals. The support all students equally, whether they are training competitively or simply looking to improve fitness, confidence, or self-defense skills. Also, for a small gym, their competition record is incredible, regularly outperforming many much larger academies in JJWL, which speaks volumes about the coaching and the level of training. Alere is rigorous, structured, and focused on real development. My kids have grown tremendously here, gaining patience, discipline, and confidence. Training at Alere has helped them gain patience, develop discipline, interact more confidently with other kids and adults, and even stand up for others at school. We couldn't be happier with the community and instruction at this gym. If you're looking for a place with excellent instruction, a supportive community, and real, meaningful growth, Alere Jiu Jitsu is the place for you. read more

I absolutely love my experience at Alere Jiu Jitsu Academy! The community atmosphere here is fantastic--it's incredibly welcoming and supportive, which makes coming to class. Beside, the coaches provide excellent instruction and techniques that are easy to understand, allowing me to pick up new skills effectively. read more

My son absolutely loves jiujitsu now thanks to Alere. Coach Jorge truly cares about his students, and all of the coaches create such a positive, encouraging environment. It was a real fight convincing my son (11yr old at that time) to give Alere a try -- he previously trained at another studio where most of the time felt like punishment instead of learning. At Alere, it's completely different. The coaches focus on building skills, they're compassionate, and the classes never feel like a cattle call. Mateo has been training here for about two years now, has made great friends, and has grown so much in both skill and confidence. 3yrs later, he now proudly says jiujitsu is his sport -- and that's because of the amazing team at Alere. Highly recommend. read more

I've practiced several martial arts since I was a kid, so I've been around enough to have seen the different ways that instructors not only teach a class but also run their business. Alere is top-notch and professional in both regards. Not only are all the instructors excellent and incredibly down-to-earth (not the case everywhere), but the community here is welcoming and supportive so you can learn from your training partners, too. As for the business side of things, unlike other places, the pricing is straight-forward; no fees for promotions, no mandatory equipment purchases/high pressure sales tactics, no structuring the curriculum in a way that forces the need for private lessons, etc. In short, all the good and none of the bad! read more

New name, same goals. Alere Jiu Jitsu is still run by the same amazing people who value community and personal growth over everything. Their commitment to high-level training, coaching, and growth is unmatched. I've personally been training here since the start of my own jiujitsu journey and never want to leave. The dedication shown by the coaches, and the community they have created, is second-to-none. Come try a class, for you and/or your kid, you won't regret it! read more

Joining this jiu jitsu academy has been one of the best decisions for me and my family. From the moment you walk in, you're welcomed like you're part of something bigger -- a true family. The atmosphere is warm, supportive, and motivating. Everyone here pushes each other to grow, not just on the mats but in life. What really sets this gym apart are the people. Jorge and Chris go above and beyond -- they don't just teach technique, they talk to every student about how to be successful both in training and in life. Their leadership and mentorship are inspiring. The team is always there for you. Whether you're having a tough day or celebrating a win, your teammates lift you up and keep you going. The academy outings are a blast and really help build strong bonds outside of training. If you're looking for a place that feels like home, helps you grow, and surrounds you with people who genuinely care -- this is it. read more

The coaches at Alere Jiu Jitsu Academy are super dedicated and patient. They provide feedback and give tailored instructions. My kids really look up to and respect them. Learning jiu jitsu here is not only good exercise but character building for my kids, learning about hard work/dedication, handling feelings when losing or winning, pushing through when it's hard and building camaraderie. Thank you Alere! read more

My daughters and I train at Alere, and we love everything about this gym. The environment, the coaches, and the family-oriented atmosphere keeps us coming back for more. We have recommended Alere to many of our family and friends who were curious about BJJ. Coach Jorge and Coach Chris are patient with the kids, and their teaching style has been effective for my girls and me. The gym offers gi and no-gi classes for kids and adults. Everyone training at the gym shares the same goal, and that is to learn and get better. Can't ask for anything more than that. read more

We were visiting from Hawaii and I wanted my daughter to train while we were in town. The coach was very friendly and knowledgeable.

Great place to train with knowledgeable and approachable coaches. Was never afraid to ask coaches Jorge and Chris any questions. Jorge is attentive while students are drilling and rolling so he'd catch things you might need improvement on and let you know. Chris' technical knowledge was some of the best I've ever experienced. He opened my eyes to some really great sequence of techniques. Also, great training partners who are skilled and who make you feel at home. Wonderful vibe here. read more

Jorge and his host of instructors are all incredibly patient with the children but also clear in not compromising technique or proper form. Our son first attended the 3 free sessions and was hooked despite being incredibly challenged in learning the moves and techniques as a very new 4 year old. BJJ has began to really help Kevin in his ability to listen, is giving him even more confidence in new ways and most of all we believe is instilling the discipline, focus and effort necessary to be successful not only on the mat but also out in the world. If this sounds at all in line with what you are looking for, give it a try and you might just be surprised with the result- I know I (even as a worry wart mum) certainly have been! Thank you Jorge! read more

Amazing gym environment with great family vibe! The instructors- Jorge and Anjinho- are friendly and know how to teach the game of Jiujitsu (combined 30+ years of experience). They care about improving the game of all their students while looking out for everyones safety. I look forward to rolling there everyday. read more

I've been wanting to begin a combat sport for some time, but was so nervous to begin. My boyfriend would rave about how much of a great experience he has every time he came here. So I decided to give it a shot & I'm so thankful I did!Not only are you learning a new sport, but also gaining a family that wants you to genuinely be the best version of yourself. I've never felt so comfortable being in a new environment. From the coaches, to my teammates, and the whole atmosphere - it's an awesome place to be! So thankful that this is now a part of my life and have great coaches encouraging me to be the greatest. Join now!! read more

Been taking my 5 yr old son for BJJ class here for the past month and he is loving it and soaking up the knowledge like a sponge. Coach Jorge is really great with the kids and so patient and caring. Highly recommend bringing your family here for an environment of good learning, exercise and discipline! read more

A good gauge of how good a martial arts class is will come from your kids' experience. I wanted to have my kids join BJJ for a long time but they were too young and hesitant. Now at the age of 8 (son) and 10 (daughter), I finally convinced them to join when we heard of Warrior BJJ opening up in CV. They were still very hesitant and on the first day of class they really didn't want to go. Well that all changed after just one class with Coach Jorge. They couldn't stop talking about it on the drive home and wanted to come back for more. Jorge has a way with kids that makes them feel comfortable and confident. He, by no means, is taken for granted by the kids as he runs a tight ship and expects respect and obedience from all his students. I recommend all parents to come and check out Warrior BJJ for their kids as they have a free 3 class trial. As for adults, it's also a great place to train and learn. As a beginner, I have been to two different BJJ academies where they seemed to cater to the higher belts. As a white belt I felt lost and confused as to what to do. The moves demonstrated were too advanced. Jorge focuses on building a foundation with basics while emphasizing safety. I feel I have advanced more in a few weeks than I had in a few months at other locations. I recommend this place for those interested in BJJ or a great workout. read more

Warrior BJJ is a well-maintained and clean facility that provides a great atmosphere for hobbyists or athletes of any age to come in and learn some great Brazilian Jiu Jitsu and get a great workout in. Professor Jorge and his team of instructors really care and nurture for those that train there while providing keen and detailed instruction on great technique that has helped myself win many of my matches at tournaments. read more

First I want to start with the exterior of the establishment. Getting there is not difficult at all, there is not much traffic getting there or leaving and parking is plenty. The gym has an open, luxurious and clean feel because of the surrounding tall windows. The bathroom, dressing room and the entire interior of the gym is well maintained. I have seen Jorge and Chris clean the mat every night that I have been to class and the borrowed gi s were taken home to be washed. Cleanliness being an important factor in a gym, is a luxury! The kids that take classes there are always engaged, participating and respectful. In the adult class everyone is friendly and helpful. Jorge is very devoted to his students. He makes sure everyone understands by repeating the technique several times and explaining it step by step. If he notices that a good amount of students did not grasp the technique he will call everyone back to a circle and demonstrate again. He ensures that every student can fully grasp and demonstrate the technique before class is over. Overall I feel very fortunate that we are part of the beginnings of this gym and I am excited to see and be part of its growth. read more

Jorge is awesome! My son was nervous and a little shy at his first class. By the 2nd class Jorge had him participing and asking to go everyday. Definitely check it out. read more

Had the pleasure of rolling at Warrior BJJ when visiting from out of town. Could not have asked for a more welcoming group of people! I will definitely be dropping back in with my family when ever we are in town. If you are looking to get into BJJ, Warrior BJJ is definitely a place I would strongly recommend! Clean mats, good vibes and a great location read more

This business discriminates against children with disabilities. We took our son to observe a class last week talked to the instructor about his disability. My son came to his first class with excitement and confidence. He left crying and his spirit and self esteem crushed by the instructor. After they had him dress they told him to get off the mat with his crutches because they have germs. While they allowed a little boy to run around coughing on everyone and everything. I 100% do not recommend this school to anyone. Don't allow your child to be there next victim. read more

Coach Jorge is amazing! He balances structure and accountability with detailed quality instruction. Go here if you want to learn proper form and technique. Coach Jorge challenges the kids ability so they are not bored and are always learning something new while practicing. My son can be unpredictable and difficult at times. Despite teaching Jiu Jitsu they have slowly helped him with discipline and failure. This place is quality over quantity. read more

Fantastic place to learn how to defend yourself and make a bunch of good friends. Jorge is a fantastic instructor, works with you where you need it mostand, explains what you're doing wrong and getting right. It's a good pace, I'm not in the best shape of my life, I'm not in my 20's anymore and I find it comfortably challenging. Give it a try, you definitely won't regret it! I also have my 2 sons registered.... working on the wife! read more

My "brother" kept telling me about Brazilian Jiu Jitsu. I was looking for a discipline for our son. When I walked into the location I had flashbacks of the original Karate Kid movie scene when Daniel walks into the dojo and well hopefully you know the rest. This place, I have to say, is amazing. The Professor is very kind, respectful and polite. He provides a family-friendly atmosphere with a great sense of balance. The place is very clean and our son absolutely loves his sessions. His confidence has increased and he gets really excited on his session days. I would highly recommend this place if you're looking for excellent instruction, friendly people and ease in knowing you are truly receiving the highest attention to detail when it comes to this discipline. Again, very family-friendly and zero pressure. read more

My twin boys having been coming here for two months and we love it. It was suppose to supplement their wrestling during the off season but they didn't want to stop coming. It's a great mix of self defense and training for tournaments. Coach Jorge explains the techniques in a safe but effective way. read more

I've been training here for several months and it's everything an academy you'd look for. Clean, great environment, and Jorge is an excellent teacher. He teaches with great attention to detail. My training partners are all there to grow and learn. Can't ask for anything else. If you're on the fence, don't be. read more

My son and daughter (5 and 7) have been going to Warrior Brazilian Jiu Jitsu for about two weeks now and they absolutely love it! I was reluctant at first to take them to a Brazilan Jiu Jitsu (BJJ) school because I there is a lot of grappling like in wrestling and I thought they would be too young for that. However, I took the leap of faith and did the free trial classes (I think 3 are included free) and found that even a child at the young age of 5 can effectively learn BJJ. Their instructor Jorge is great with kids and does a great job at making the BJJ classes not only instructional but also fun! Other things to note. - Flexibility/lots of classes: there are kids classes everyday during the weekdays Monday - Friday. - Parking: this school is located in a relatively quiet strip mall along Castro Valley Blvd so parking directly in front of the school is easy and convenient. - It appears that there is another Warrior Brazilian Jiu Jitsu school in San Ramon. It looks like that school has great reviews as well! read more

I wanted my daughter to try BJJ not only to learn to defend herself but to learn how it is to push herself when she gets tired and when things get difficult. Knowing that there was a potential for her to not like it, I was thankful that they offer 3 free sessions when you start. She was a bit tired in the beginning warm-ups but Jorge knows how to keep it fun and interesting for the kids, and she was right back in there. He's aware that the kids have short attention spans and structures the class based on how the kids are doing that day. You can tell Jorge is passionate about teaching BJJ to the kids as well as the adults. Yes I took a class too! We will be back! The studio is beautiful, and clean. Parking and getting to the location is easy. They're next door to the Kasper's. read more

Such a wonderful place for people of all ages. My 6 year old daughter has attended class here for a little over a year. Although initially a little scared and nervous, she has competed once and is preparing for her second competition now. Coach Jorge is very patient and so good with the kids. All the coaches have been great! She always leaves with a smile on her face and it has positively impacted her life in ways I never imagined. I am excited to start my son very soon. I've also made friend with other parents and this place is like another home/family. It's such a wonderful community. read more

My son has been attending Warrior Brazilian Jui Jujitsu since around the time the Castro Valley location opened and he thoroughly enjoys it! The owner, Jorge, is the kindest and most patient person and just fantastic with the kids! He's very knowledgeable and is very age-appropriate with the training. My son has learned a lot and has formed a really solid foundation so far. We have attended both the 5 - 7 age group as well as the 8 - 12 class (which we made the switch soon after my son turned 8). Jorge weaves in the necessary tactics with a lot of fun. For example, he details the moves and then the kids practice with close supervision and they are typically paired with a child of the same size. If they need more attention, Jorge or his assistant will spend more 1:1 time going over the moves. At the very end of class they typically play a fun game ("bull dog") which is great to see the kids just let loose. The location is very clean and organized, and there's a lot a lot of seating for the parents and siblings. I love how the schedule is very flexible as many of us are juggling many activities. Parking is also a HUGE plus as there is plenty. I highly recommended Warrior BJJ to anyone...and you have nothing to lose with the 3 day trial! read more

I highly recommend this location , they helped my son with confidence, self defense and discipline. Jorge is great with kids . The location is perfect , lots of parking and very clean location.
