St. Rose of Lima School History
The history of St. Rose of Lima School is deeply woven into the roots of Simi Valley itself. St. Rose of Lima Church, established in 1921, was originally located at a now-historic site in Strathearn Park, where the primary building still stands. The parish had a wide reach, and is community grew quickly.

By the late 1950s, the church’s pastor, Father Patrick McDonagh, realized that the community needed more spiritual and educational support to meet current and future needs. He and his parishioners had a vision of creating a larger church and an adjoining school, along with supporting facilities such as a rectory and a parish hall. Once the master plan was set, parishioners began pledging funds immediately.
