It's so much more than a jiu jitsu gym. Steve and his coaches have built an awesome family that you can be proud to be part of. Whether you want to compete or learn a new skill/hobby they have classes for you and also a weight room to help with fitness/weight-loss goals and cold tank/suana for recovery. As an added bonus they host seminars and grappling events.

If you are a small woman who wants to learn how to defend yourself but intimidated enrolling in a bjj school which is a predominantly male sport, this is your place. You have to at least try a class. They have kids womens and fundamental classes..I have already learned a lot in the 2 weeks that Ive been going. It is a very welcoming gym with great people. Ego will have to be left home coz it is non existent here. The owner Steve and all instructors are very helpful in giving tips and making sure everyone’s safe during classes. The culture is very nurturing for scared beginners like me. Also a bonus that they have a lifting area(for strengthening)Ice bath and Infrared Sauna. Goes to show they do care about their students health and recovery as much as teaching the sport. Love everything about this place.

Atmosphere? A1. People? A1. Love training here and learning from everyone. When i decided to start my jiu-jitsu journey I wanted to be apart of something that’s both competitive and enjoyable. Since joining 10th Planet, I feel at my best physically and mentally and couldn’t be happier being apart of this school 🙏🏼
