Carolina Bossi Silva Batista
"My daughter has been taking jiu-jitsu classes here for a few weeks now, and we’re absolutely loving it! She gets so excited to go to class and truly enjoys every minute. The instructors are amazing — patient, kind, and really great with kids. It’s been wonderful to see how much confidence, discipline, and joy she’s gained in such a short time. The environment is very welcoming. Highly recommend!"
Dave Kim
"Amazing community and instructors! The program for kids is well-structured, fun, and engaging. Having been a collegiate wrestler and having more than a decade of experience as a multi-sport high school coach, I know what quality instruction looks like, and this is it! The classes are run with the right balance of empathy and compassion for kids and a sense of discipline and a no-nonsense let’s-get-to-work culture."

"I’ve been training at this Brazilian Jiu-Jitsu school for a while now, and I can confidently say it’s been an amazing experience. The black belt professors here are absolutely top-notch – they’re not only highly skilled but also incredibly detail-oriented, ensuring that every technique is taught with precision and clarity. As someone in my 40s with kids who also train at the school, I’ve been impressed with how well the pace and intensity of the classes are balanced. The training is accessible for someone like me, and I’ve been able to progress steadily without feeling overwhelmed. The professors are great at adapting techniques to suit different ages and skill levels, and I’ve seen the results in both my own progress and my kids’ development. Highly recommend this school to anyone looking to train in Jiu-Jitsu, regardless of age or experience level! Bruno"
