 At one-time Holy Redeemer High School was separated as a boys high school and a girls high school.The boys high school was administered by the Marist fathers and the girls high school was administered by the I.H.M sisters.The Marist fathers left Holy Redeemer at some point in the late 1940s/early 1950s and the I.H.M sisters took over administration of the combined girls and boys high school at that time.
