School History

How we began…

Outside of St. Catherine of Siena School Denver, Colorado

At the request of Monsignor John H. Mulroy, pastor of the newly formed St. Catherine’s parish, the Sisters of St. Joseph of Carondelet opened St. Catherine’s school on September 6, 1921. One hundred thirty students were enrolled in grades one through six in the church basement. Using funds raised from the Parish Festivals, the gymnasium, convent, and finally the new school building were built. The school was blessed and dedicated on May 26, 1929. Due to demands of increasing enrollment, the building was enlarged in 1949. Enrollment reached an all-time high in 1957, with 565 students in grades 1 through 8. Our kindergarten first opened in 1977. The school has been blessed through the years, with many concerned pastors and religious women who made St. Catherine’s a school of the Church, serving People of God with authentic religious instruction and academic excellence. Our Pre-School was established in the fall of 2005. An institution in Northwest Denver, St. Catherine’s seeks to continue to live up to its reputation of high academic and athletic achievement.
