I cannot recommend this place enough. The professors here are so kind and knowledgeable and the perfect place to go whether you are a beginner or advanced. We took my.daughter for the past 9 months or so and it has been amazing to watch her grow, develop her skill, and interact with students and staff. Again, if you are in the area and even thinking about starting, this is the place to go!

Great gym, great people, no egos. Instructors make you feel welcome and there is a good mix of hobbyists and competitive Jiu jitsu players. My only complaint is that Wellington keeps beating me up but one day I'm gonna tap him out....don't tell him I said that.

Mo and Giva are excellent and come highly recommended by my brother, whose three sons grew up under their teachings! My son loved it and will be coming back for sure!

One Jiu Jitsu has been awesome. My 5 year old has been attending regularly for about 3 weeks so far and really enjoys it. He's on the high energy side and can have a hard time focusing sometimes. I feel like all the instructors do an excellent job with the younger kids. They are engaged the entire time and have fun, along with learning lessons and techniques that are simple enough for them to follow. They do an excellent job of keeping my son on task and work with him to make sure he's learning and involved. I would definitely recommend a visit if it's something you are interested

I have been training here for nearly a year now and have nothing but great things to say about this place. I came in as someone who had no martial arts background whatsoever and all of the professors really truly care about each individual. Giva knows every single students name, which as a gym owner myself is an incredible feat. It is a testament to their passion for Jiu Jitsu and teaching. I am proud to be a member here and grateful for their guidance.
