Owner/Head Boxing Coach Mark Sutton
Born and raised in the Bay Area, CA, Mark started boxing when he was 15 years old. After learning the basics at one of the top boxing gyms in Oakland, Mark moved to Los Angeles in 2012 and started training under the late, legendary California heavyweight champion, Coach Stan Ward. Coach Stan would develop Mark’s boxing style over the next few years, spending countless rounds drilling and sparring amateurs and future pros at different gyms in the area, and sharing knowledge from the golden era of boxing. Following Coach Stan’s passing, Mark committed himself to coaching, aspiring to make the same significant impact on others that the sport had made on him. In just a few years of coaching, Mark has produced multiple Golden Gloves champions and state champions from scratch.
