After his nine-year NFL career, Broussard spent four years coaching high school football in California. He was the offensive coordinator at Don Lugo High School in Chino before going to Diamond Ranch High School as offensive coordinator in 2001. He became head coach at Diamond Ranch in 2002 and coached until 2003. His first season as head coach resulted in success with the Diamond Ranch Panthers taking the Mt. Baldy League Title. For the 2003 season, the Diamond Ranch Panthers were the heavy favorites (ranked #1 in preseason Mt. Baldy League) to take the league title once again with several returning seniors on offense & defense, and a talented junior class that featured three division I prospects. The Panthers finished 1–4 in Mt. Baldy League play for the 2003 season.
