Boxing
Beaverton

James began his American Boxing training in 2002 at State Street Boxing in Santa Barbara, CA. There, he acquired his attention to the fundamentals of boxing and disciplined skill building from head coach Josh Schneyer. Later, James went on to train in various Southern California gyms and fought out of City Boxing in San Diego. More than anything, he feels priveleged to have had the opportunity to learn from and spar with many great coaches and fighters including former WBC and IBF Minimum Weight Champion, Manny Melchor. Inspired by his past and present experiences in boxing, James focuses on the basic principals of proper punching, defense, and movement with his students.
