Legendary De La Salle High football coach Bob Ladouceur announced his retirement as the school's varsity head coach Friday.
Ladouceur, 58, took over the program in 1979 as only the second coach in school history and had no prior head coaching experience.
He quickly built what has amounted to the most dominant high school football program in history. Perhaps best known for the Spartans' national record 151-game winning streak, which spanned from 1992 to 2004, Ladouceur is 399-25-3 in 34 years as head coach.
He's California's all-time winningest coach and owns the best winning percentage of any coach nationally with at least 200 wins.
De La Salle hasn't lost to a team from Northern California since the 1991 North Coast Section title game against Pittsburg, which was the last loss before the vaunted streak began the next year. The Spartans have won the last 21 NCS titles since and recently wrapped up their first 15-0 campaign in Ladouceur's tenure.
All signs point to offensive line coach Justin Alumbaugh as his replacement. Alumbaugh has served on the staff since 1998 and was a De La Salle linebacker during the streak.
Under Ladouceur's watch, De La Salle has won seven mythical national championships, including five from USA Today. The Spartans have won the last four California Interscholastic Federation Open Division Bowl games.
Notable De La Salle players who went on to play in the NFL include: Maurice Jones-Drew, D.J. Williams, Amani Toomer, Aaron Taylor.
Ladouceur, a San Ramon resident, went to San Ramon Valley High in Danville and later graduated from San Jose State.
