    My family and I recently moved from South Bay last year. I was doing a summer for BJJ before I…read moremoved and after getting situated into our new home I decided to get back in the gym. I was not very well versed in all things BJJ at the time so I will share my experience accordingly. First things first, I didn't understand the big differences between Gi and no-Gi BJJ. It is a critical question you need to ask yourself what you prefer before getting started. Before the move, the gym I practiced at was using Gi. Honestly, I think the Gi sucks! My hands would get hurt getting stuck in grips, extra rashes, and damage to my ears and face. Everyone was taped. It is just more brutal on the body IMO. As an 'old man' for this sport longevity was one of my deciding factors. That being said, THIS gym is no-Gi which I would recommend over Gi. The other part I will mention is about this gym itself. The support and comradery of the coach (which draws the quality of students) and the students are extraordinary. Coach is VERY hands-on, teaches most of the classes and even does roll with his students on occasion. Ending note...everything is clean, sanitary, and professional. No bullshit BJJ gym, get in here and give it a try (for yourself or kids)!

He encourages focus and dedication to grow in karate, and sees the students for who they are and is able to meet each one individually as well as the group. He includes philosophy in his classes and has older students help to demonstrate more sophisticated katas and help the younger students as well. We are very satisfied with our karate experience, our son loves to go! I am amazed at how much he has learned in almost one year. We look forward to signing up our daughter when she is old enough :-)

    Mires Martial Arts is a great dojo for you to learn karate and life skills. The schedule is very…read moreconvenient as the dojo offers several times each day to accomodate multiple schedules. My daughter and son both joined and have learned much more than karate. They were challenged to work hard to earn their belts and stripes never given anything but earned it by practicing and taking feedback. They both are more confident with their self defense but also with handling confrontations, what to do in specific situations, and how to deal with difficult feelings and people. All of that in a fun welcoming setting. My son is learning new weapons and has partaked on the beach session. Sense Geoff has a fun teaching method to engage participation and creates an environment that brings enthusiasm and engagement in learning. He is always maintaining a safe environment for every student and also pushes them to challenge themselves to be their best. He has a great sense of humor making learning fun while he still maintains discipline over the group. He is building confident and respectful students that will benefit from his teachings for a long time. He has some students attending over 10+ years that still show up growing up with the dojo which is a testament to his teachings for all ages. Thank you Sensei keep up the great work.

We were invited to an "invite only" multi-gym rumble, where kids sparred in a no-points, no-pressure environment. All the kids from my dojang loved it. My boys also attended a sparring clinic with Coaches Arven and Kris, both world-class level athletes. The individual coaching was top-notch, and my kids thoroughly enjoyed training with them. The dojang is well-kept, and the mat is nicer than standard tournament mats. Parents can watch from the hallway through large windows. The facility includes a snack bar, and the bathrooms are clean. **Pro-tip:** Park in the parking lot near the dojang--it's a shorter walk and usually has more open spots. Overall, Sparta Taekwondo offers an excellent environment for both training and community. Highly recommend!

    5 stars because there's no 10 stars!…read more My family and I have been training at Dogo Krav Maga for about six months now, and I can't say enough good things about this place. From day one, we were welcomed like we'd been part of the community for years. Gustavo, Gustavo Jr., and Samantha are incredible coaches -- knowledgeable, patient, and genuinely passionate about teaching proper technique. They have a way of breaking things down so anyone can understand, whether you're brand new or already have some experience. More importantly, they really care. They notice when you're improving, they push you when you need it, and they always make sure you're learning in a safe, supportive environment. The atmosphere here is exactly what we were looking for. It truly feels like a family. No egos, no intimidation -- just people of all ages and skill levels learning, growing, and having fun together. In the six months we've been here, I've watched my family's confidence, fitness, and overall mindset improve in a way I honestly didn't expect. Being part of this community has made a real difference for us, and we're grateful to be here. If you're considering Krav Maga or just looking for a positive place to get stronger and more confident, Dogo Krav Maga is the real deal. Highly recommend.

My son started Kung Fu at 9 YO and in 2 years he's gained discipline, focus, coordination, confidence, internal motivation, and great friends! Students progress at their own pace. Attendance days are flexible - with a monthly tuition, kids can attend any classes of their belt level (there are 5 every week). After a whole-class warm-up, kids break up into smaller groups and work on specific skills with the instructor and student assistants. The school holds optional tournaments and seminars, giving students an opportunity to set goals and train for specialized skills. Self-defense is emphasized and specific techniques are taught at each belt level, which build upon the previous ones. Anti-bullying measures, empathy, and conflict avoidance are also discussed. The instructors teach respect inside and outside of the school. I've been taking Kickboxing with Sihing Braydan and I absolutely LOVE it! Twice a week, a small group of adults work hard, push ourselves beyond what we ever thought we were capable of, and share lots of laughs too! It's a great way to end the day - exercising stress away, getting stronger, staying sharp, and feeling invigorated too. There are many fun events throughout the year, including the Lunar New Year celebration featuring our talented Lion Dance Team, who perform throughout the Bay Area. My son has had 2 birthday parties here, and they will tailor the event to your party theme, like Star Wars! I have also taken their Self-Defense course, which is open to the public and is extremely informative and empowering. I highly recommend it to all teens and adults. There are wonderful opportunities here from littles to seniors. Come try a class in Kung Fu, Kickboxing, Tai Chi, or Self-Defense, and gain mental & physical health, self-confidence, and a warm, supportive community.

He peered into the windows of the studio one day and we met Sifu Mike. We felt welcome right away. I've watched my son grow into a more confident and respectful young man over the past year. He loves Kung Fu and looks forward to class. Sifu Mike is his favorite as he enjoys the humor and good nature that he has with the kids. It is a great reason to get out of the house for all of us. There are events for the families often and they embrace community. I hope that he continues on his Kung Fu journey throughout his life. I know that with One Tribe as his start there is a good chance of that happening.

Sifu Mike, Sifu Luke, Master Barbosa, and all the Sihings and Sijehs are amazing! They connect with each student, provide personalized feedback and training, and teach Kung fu with a focus on their values of respect, moral integrity, wisdom and kindness. My daughter really enjoys the classes, learning her forms, and sparring sanshou/ sanda style. A few standouts for us are their weekly seminars, which teach extra skills like self-defense, and the high number of strong female role models in their teachers and students (which inspires my daughter to do better!). They also offer online classes and have an app for signing up and scheduling. Overall I highly recommend One tribe martial arts and encourage you or your child to sign up for a trial if you're considering learning martial arts!
