This academy has a special…read moreplace in my heart as it is where I started my BJJ journey - I've learned a ton here and signed up for my first two competitions while training here! I mainly attended the no-gi & wrestling classes, but both the gi and no-gi instruction was great. On the surface, Serao is a friendly, humorous and fun place to train for hobbyists. People are nice, it is kid-friendly, and bad behavior gets rooted out immediately. Leo goes out of his way to create a safe training environment (he'll match sparring partners himself) regardless of skill, size, or gender. The instructors are great and care about your development. Underneath the surface, you'll find a small, tight knit group of competitors that train intensely and compete at an extremely high level. There's something for everyone here, I'd highly recommend it and as a bonus, parking here is extremely easy and accessible. Will miss this place!

GUERRILLA Jujutsu has been nothing short of excellent for my son. He's been training there for six…read moreyears, and every single time we go, he's just as excited to step on the mat and learn as he was on day one. Over the years, my wife and I have seen his confidence soar, his patience grow, and his dedication deepen. A lot of that credit goes to the consistent environment and the incredible coaches. They are hands-on during training and truly invested in each child -- not just in helping them succeed on the mat, but in guiding them to grow off the mat as well. I highly recommend GUERRILLA Jujutsu to any parent considering martial arts for their kids. Take the time to check them out and connect with Coach Matt -- you won't regret it.

Sunnyvale MAA is so much more than a martial arts after-school activity for our family. It has…read morebecome a true community that we are incredibly grateful to be a part of. From the very first visit, something felt different here. Nearly three years ago, I had explored another martial arts studio in Sunnyvale, and the experience felt impersonal and it just didn't feel like a place where my kids would truly belong. I didn't experience any of that at Sunnyvale MAA -- not on day one, and not now. What sets this place apart is the people. The instructors and the entire team here genuinely care -- not just about teaching technique, but about every single child as an individual. I have two kids enrolled, and I'm consistently amazed that all of the instructors know little details about both of my children, even the ones who haven't directly taught them. That level of attentiveness and personal connection is rare, and it speaks volumes about the culture and team have built here. My oldest started hesitantly, he told me he only wanted to make it to his second belt. That was his ceiling. Fast forward almost two years, and he is now setting his sights on black belt. That transformation didn't happen by accident. It happened because the instructors strike such a thoughtful balance of discipline, encouragement, and genuine support. They push the kids to grow while making sure they feel safe, seen, and celebrated along the way. Watching his confidence soar has been one of the most rewarding things I've witnessed as a parent. And the impact is contagious. My youngest spent nearly a year watching her brother thrive on that mat, and she couldn't wait any longer, she recently joined the Little Dragons program and absolutely loves it. Seeing both my kids light up when they walk through those doors, excited to see their friends and their KJNs, says everything. The community here is welcoming, inclusive, and warm in a way that is hard to put into words but impossible to miss. If you are on the fence about enrolling your child, come watch a class. You'll feel it immediately, and so will they.

My daughter started at SVMAA when she was 5, in the Little Dragons class. We initially enrolled her…read moreto help build her body confidence, and now, four years later at age 9, she's gained so much more: confidence in herself, perseverance, and discipline. She's now part of the performance team, where her teachers continue to push her growth not just in martial arts skills, but in teamwork, mental resilience, and leadership. The care that the owner and instructors put into their school is clear in everything they do. The teaching is structured and challenging, with high expectations, yet always warm, kind, and adaptable to each child's needs. The curriculum and expectations are clearly communicated, and the class schedule is very flexible, with multiple sessions offered for each level throughout each day to ensure that each family can choose the schedule that works best for them. I'm so grateful for SVMAA. It's an incredible community that has brought out the best in my daughter.

I've been training for over a decade, on both coasts, and across multiple schools. I've trained at…read morecollege clubs, hobbyist gyms, and schools with world class competitors/instructors. When COVID hit and I had 2 kids, I took a hiatus from BJJ for a few years. When I returned to the sport, I knew I was going to be picky about where I chose my next gym to be. Joining Sunnyvale Jiu Jitsu was a no brainer for me. The vibes: immaculate. It's no surprise that with little to no marketing or online presence to date, they've been able to build up a solid base of students (both new as well as transfers from other schools) simply through word of mouth. It is a family friendly environment, with high skill and low ego. The quality of instruction: top notch. A lot of gyms you go to teach haphazardly at best. Jian probably spends more time thinking about the best way to structure his classes than he does on anything else. He's familiar with everyone's individual style and is always looking to help optimize their specific game. The training: tough. There are enough high level people here that I can go through an entire 2 hour open mat only rolling with brown and black belts if I wanted to.

I was previously focused on only powerlifting, and although I thought I was strong, I was massively out of shape. I was looking for a place nearby, and have always wanted to train Jiu Jitsu after watching the UFC. Professor Alberto and all the coaches are professional and instructive. At the same time, Alberto knows how to motivate each student to achieve their goals. He doesn't have a cookie cutter approach, and knows how to squeeze the juice out of each person. Whether your goal is to get in shape, be more proficient at grappling, compete, or just have a community, it's highly likely Daruma would be a good fit. If you're in the Sunnyvale area, highly recommend you check Daruma out.

What truly sets this gym apart is Professor Alberto. Having an active black belt coaching young kids is impressive on its own, but his genuine passion for teaching youth is unmatched. He knows every single child by name from day one and has a unique ability to break down complex, technical movements into creative, engaging, and fun concepts that kids easily grasp and remember. He strikes the perfect balance between structure, skill-building, and fun, keeping the kids motivated and excited to step onto the mats every session. They always have another 3-5 other blue/brown/black belt coaches helping out to keep the coach to student ratio very small. The facility itself is top-tier--always spotless, well-maintained, and meticulously cared for, which brings complete peace of mind to parents. Beyond the high level of instruction and clean environment, the sense of community at Daruma Dojo is remarkable. They go above and beyond to make families feel welcome with hosted summer BBQs, pool parties, and events that bring everyone together. If you're looking for a jiu jitsu gym that builds confidence, technique, and real community, Daruma Dojo is the gold standard. Highly recommended!
