Harold Warren enters his fourth season as associate head coach of the USC women's soccer program. He and USC head coach Ali Khosroshahin were teammates at Cal State Fullerton after spending several years playing for rival club teams in Southern California. Now reunited at Troy, the pair joined forces to help guide the Trojans to their first-ever NCAA Championship in 2007. The defensive-minded Warren joined the USC staff after serving as an assistant coach at Arizona for four seasons.
"We are extremely fortunate to have someone of Harold's experience, knowledge and management skills," head coach Ali Khosroshahin says of Warren. "Harold could easily be running his own program, which makes it all that much easier for us to do what we do here. His work with our defense speaks for itself!"
While at Arizona, Warren helped guide the Wildcats to an NCAA Third Round appearance in 2005 under head coach Dan Tobias. In his four seasons at Arizona, the Wildcats posted a 40-35-7 overall record and went 13-19-4 in Pac-10 play.
Before arriving at Arizona, Warren served one year as an assistant at UC Irvine in 2002, where he was also responsible for directing the UC Irvine Soccer Academy. From 2001-03, Warren was the assistant coach for the California Olympic Development Program's 86-87 age group, and was an ODP scout for Southern California male and female talent.
Warren spent 17 years coaching at the club level for boys and girls teams ranging from 10-19. He won league championships with Riverside Soccer Club and Long Beach Sidekicks, and helped the West Coast Stingers to a Surf Cup semifinal. From 1991-92, he was the head coach for the boys varsity team at Savanna High School in Anaheim.
As a player, Warren was a defender and a forward at Riverside Community College before transferring to Cal State Fullerton in 1989. He then transferred to Cal Poly Pomona, where he graduated with a bachelor's of science in communications in 2002.
