Louisville High School is a college preparatory, Catholic high school for young women with a long and proud academic tradition. Founded in 1960 by the Sisters of St. Louis, Louisville’s heritage can be traced to the mid-1800s when the Sisters of St. Louis were founded in France. Coming to California from Ireland in 1949 the Sisters were led by Sister Mary Ronan, who was inspired to move forward with confidence in God and openness toward the horizons of the future.

In September 1960, the old Manzanita Ranch with its wooded canyons, green fields, and white-painted horse corrals became the site for Louisville High School. Ninety-one young women and five teachers formed the nucleus of what is today one of the finest Catholic college preparatory high schools in Los Angeles for young women. The faculty and students came together years ago with a common vision: to create a Christian community for spirituality, learning, and outreach. Today the vision of those pioneers is a reality. Louisville High School has matured into a lively family of individuals, all engaged in the exciting process of learning.
