History
In its relatively short history, Brentwood School has grown to be one of the premier independent day schools in Southern California. Founded as a non-profit corporation in 1972, Brentwood School acquired the Brentwood Military Academy, which had existed since 1902.
Brentwood School opened in the fall of 1972 as a co-educational, college preparatory day school with grades 6-10. Grade 11 was added in fall 1973, and the school graduated its first senior class in June 1975.
In 1994 Brentwood School purchased the Marymount Junior School campus on Sunset and Saltair and opened a Kindergarten through grade 6 campus in the fall of 1995. The 22-acre East Campus Athletics Complex was completed in 2001 and the Student Life Center was completed in the spring of 2005.
