Coach Eddie Adrian Arnove

Part of the fight team, Coach in the Kids and Pee Wees Program, I love action and martial arts films. Being a fan of action and martial arts films, I always wanted to do the moves I saw on my favorite films. This desire sent me on a path to find a coach to teach me martial arts. After being at OCKMMA for 4 years I took up teaching the kids classes. So far I have fought in 2 amateur Mauy Thai fights, compete in 5 local grappling tournaments.
