Dennis began his martial arts career in the striking arts. He started in kickboxing before moving into MMA in 2009, where he built a 5-3 amateur record. It wasn't until 2013 that he dedicated himself fully to Jiu Jitsu. Now a black belt, Dennis has devoted himself to investing in his students and growing a team of skilled and knowledgeable Jiu Jitsu practitioners at the Butcher Shop.
