After training 2 years at another gym, I took two of Andy’s fundamental classes and he cleaned up 99% of each of the positions I thought I knew. He taught all these little details on high-percentage moves that made them so much easier and effective. I even learned a ton from their black belts during live rolls. One was knee-slicing right past my guard so he taught me the defense (outside butterfly grip and kazushi the side they’re slicing to in case you’re having the same problem I was). Such an awesome culture: super-informative, competitive, and kind.

Fantastic friendly learning environment that welcomes individuals from a multitude of fitness levels and athleticism. Highly recommend swinging by to try it out and become part of a great community.

I was out of state for a business trip and found this gym close to my hotel. I train back home so I decided to drop in for a class. It was great. Everyone was welcoming and the training was fantastic. A++

Went to the 11AM class, Coach Isaac was very knowledgeable and accommodating. Visiting from st. Pete, FL, and felt welcomed from the moment I walked in. Great training partners and great vibe in the whole place. Everyone was ready to learn and Coach Isaac got us all a little better! Thanks for the great gym, will be back before I travel back to FL.

Life happened and I wasn't able to continue, but they were very good at making things efficient. Cancellation time, response period, following up. They are 5 stars in my book. only suggestion would be for those who are more time sensitive...start and end at the designated time. And having a clock in the main floor would be nice.

I went to the free sample session today. All the students were very friendly and welcoming, like a big family. The staff were also very attentive to me as a newbie. I definitely can’t wait until my next class.

Outstanding instruction in a friendly environment, with terrific people to train with. Whether you're a total newbie to grappling or an experienced grappler you'll find a home at 10P Fullerton. Coach's Isaac and Andy bring a broad perspective and offer classes at times that will fit any schedule. Do yourself a favor and check it out!

Great coaches and people with a positive, friendly atmosphere. Our family has been practicing here for a couple of years, and they love it. My son is now an assistant coach to the little kids class. What a great mentoring system they have!

The coaches here are world class. Wether you want to learn self defense, or take yourself into the professional ring, or if you just want to learn something really cool, any one of these coaches are well equipped to help you along your journey. I've personally trained with each coach staffed here and I can't give a higher review than the best. The facility is a great place, tons of parking, and a welcoming environment if you're just starting out. I would absolutely recommend this gym to anyone even remotely interested in jiu jitsu.

What a great group of people!! Came into town for No GI Worlds and needed a place to train leading up to comp. I reached out to 10P Fullerton and was welcomed with open arms. The team was welcoming, kind, and made sure that everyone knew to be respectful of the pace since people were competing and some were in there just to move their bodies and didn’t want hard rounds. I was able to roll with a couple of the coaches and they provided me with great feedback when I asked. Highly recommend stopping in or joining if you’re in search of a school!

Came in for 2 sessions while I was visiting from out of town. Folks were very welcoming and Coach Isaac gave some thorough and technical instruction.

Amazing atmosphere and great coach. I've only been training for 4 months now at the gym but I feel like I learned a lot thanks to coach Isaac. Everyone's friendly and willing to teach.
