History of Brentwood

In its relatively short history, Brentwood School has grown into a premier independent day school 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.
