Welcome to St. Mark Catholic School. It is our hope that this website will serve as a useful tool for our current parents as well as those parents that are seeking a Catholic education for their children.

St. Mark Catholic School is a fully accredited Pre K-8 Catholic School. We are conveniently located in South County, St. Louis, right in the middle of the Affton-Lemay area off Union Road and near I-55 and Reavis Barracks Road. (Map to 4220 Ripa Ave.)

At St. Mark, we provide a safe and family-oriented environment where your child can flourish. Our dedicated faculty and staff educate students to be active Christians, lifelong learners, problem solvers and responsible citizens. We take a personal interest in each and every child, providing the rigorous curriculum to answer questions, and the nurturing guidance to help them achieve dreams.
