Vitor skillfully arranges training partners to challenge the competitors and protect those with injuries so that everybody can work hard, improve their jiu-jitsu, and learn. Caio invests so much time and energy into making precise videos for our learning. I really appreciate how much he cares about our jiu-jitsu. The academy is really the cleanest, nicest academy I've ever trained in. Caio even put ergonomic chairs and desks for us to study and places for families to sit. He cares about the environment very much. He even had the team create a wall after a truck drove into the academy, just to make sure that nobody missed training, which is so important for our mental and physical health. Is your gi still wet from training the day before? Did your best floofy buddy submit your gi? Don't worry -- there are loaner gis for you to borrow. Just get to the academy and train.

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.

I asked about the program and they didn't have any helpful context to share about it but they told us to just stay and watch. In addition to the disappointment we experienced from the staff, the studio itself was disgustingly dirty. We switched seats because we noticed a layer of grime on the several seats and left early when we saw that it was a dirty studio throughout. I have already visited a few studios during my search and this is one I wouldn't recommend.

Avoid Batata Brazilian Jiu-Jitsu…read more My son (almost 12) has trained Brazilian jiu-jitsu for 4.5 years. We visited simply to evaluate whether this gym would be a good fit. Within minutes, it was clear the kids class was made up almost entirely of much younger, much smaller beginners. That's not a criticism--it's just not an appropriate training environment for an older, experienced kid who needs the right partners to develop safely. I asked if there were other classes or days with a different mix. I was told this was essentially it. So I politely said it wasn't the right fit and thanked them for their time. That should have been the end of the interaction. Instead, Mr. Batata himself--not just a coach, but the owner--became immediately confrontational in tone, stepped into my personal space, and began making assumptions about why we were considering switching gyms, as if we were doing something wrong by even looking. He then launched into how this "isn't just a business," implying I should somehow structure my life around loyalty to a gym--despite the fact that we were there for the first time and simply trying to make the best decision for my son. It was unreasonable and completely out of line. I calmly explained that we take this very seriously and that changing gyms is a big decision. That didn't matter--he dismissed it and continued with an aggressive, condescending tone. As I was leaving with my son, he kept talking at me, and another instructor joined in. At that point, it crossed from uncomfortable into completely unprofessional. No parent should have to walk their child out of a business while being talked at for simply saying "this isn't the right fit." The entire interaction left both me and my son feeling unsettled and, honestly, a bit icky. That's not something I've ever experienced walking into a jiu-jitsu academy before. This wasn't a misunderstanding. This was the owner reacting poorly to a polite "no," and doing so in front of a child. If this is the tone set at the top, it raises serious concerns about the culture and judgment being modeled in that gym. We walked in open-minded. We walked out uncomfortable. There are plenty of gyms that know how to treat people with basic respect. This is not one of them. Avoid

I was pleasantly surprised to find out that a gym opened up much closer to where I lived. I was even more surprised by how much I have enjoyed the people that I've met (and rolled with) at Daruma. When I picked my very first gym, I passed on at least 3 different gyms because of the culture. In one of the gyms, the head coach/ professor didn't seemed involved. At another gym, I was being pushed to buy long term memberships and their expensive gi/ uniform. I never got those feelings with Daruma. Everyone has been super kind and supportive. The Milpitas location is still a relatively new (as of 2026) so some of the adult classes have a smaller turnout. This can be really good for people just starting in the sport, but I personally just like to roll. My step son also started Daruma with me and he loves it. The class structure is very fun and the coaches are really good about watching out for the kids safety. It's also been a really great experience for me and my stepson to bound over this shared activity.

Daruma Dojo originally opened in Sunnyvale, and we're so glad they expanded to Milpitas. A friend recommended this place to us, and it definitely did not disappoint. Daruma Dojo offers classes for kids/teens and adults. Adults can choose from morning or evening classes. For kids, ages 4-6 attend class from 4:30-5:30pm, while 7-15 train from 5:30-6:30, Monday through Thursday. Friday and Saturday classes are combined for ages 6-15. It's truly a family-friendly environment - so much that some parents have even joined after seeing their kids train! Membership also allows access to both Milpitas and Sunnyvale locations, though we haven't visited the Sunnyvale location yet. The front staff are friendly and welcoming, and the professors and coaches are patient and do a great job of explaining techniques in a way kids understand.

Wildcat offers MMA, Muay Thai, boxing, and BJJ, and the level of coaching is elite. However, what truly separates Wildcat from other gyms (at least in my opinion) is the people. It's not just that the coaches are high level fighters and technicians that are honest people who care about your growth - everyone here is like family. Coach Alex in particular has had a huge impact on me. His guidance helped me build discipline, confidence and direction. As well as how to apply those lessons to life. He pushes you when you need it, not want it. He'll support you if you're struggling, and genuinely wants the best for you. Coach Murph has always looked out for me, helping me fine tune my technique and pushing me to level up. Having Coach Murph in your corner makes all the difference. I've been in martial arts 3 years and have tried a few places before finding my home with Alex and Wildcat. I can say with confidence that you want to be here - whether you're brand new, experienced, or trying to compete, everyone is treated with respect and encouraged to grow at their own pace. If youre seeking somewhere to train, improve yourself, and be surrounded by positive, driven people. You've found it. Joining Wildcat was the best decision I've ever made.

Myself and my wife feel especially blessed to have their coaches in our lives and have groomed my son to be excited, involved and experienced, especially in the art of taekwondo along with the other classes they offer that include jiu-jitsu and wrestling. If you are looking for a gym, whether you are a younger child, teenager or an adult, I highly recommend this gym. The coaches are very keen on teaching the students the art and appear to have a very experienced successful background from a high-level and have been coaching for many moons. If you are not a student and are interested in any of these art forms please check this gym out. It will help your kid to grow, get skilled in the art of self-defense and become more disciplined along with really having a great time. Never a dull moment at the gym!
