Training there for 10 years, he left in search of further knowledge. He continued training at RAW gym (later became R-1) in El Segundo, one of the first “MMA” gyms in America, from 2001-2008 with high level Division 1 wrestlers such as Rico Chiaparelli, Frank Trigg, and Vladamir Matyshenko (both UFC fighters also).
