Mt. Carmel High was founded in 1935 at 71st and Hoover streets in Los Angeles. The school closed in 1976 due to declining enrollment and a few years later was destroyed by fire. Although the buildings had fallen, the school was designated as a Los Angeles Historic-Cultural Monument, and the spirit of the Crusaders endured.
In 2002, a group of Mt. Carmel graduates formed the Mount Carmel Alumni Foundation with the goal of reconnecting fellow graduates. They've since expanded their vision to include supporting Catholic elementary schools in greater Los Angeles and raise funds for retired Carmelite priests.
