The Archdiocese of St. Louis has developed a new system for safe environment compliance called Prevent and Protect STL. Everyone ministering to minors and vulnerable adults in the Archdiocese is required and asked to register in the new system. St. Mark Catholic School follows these requirements. Detailed information is in the links below. If you have any questions, please contact Mrs. Mary Althage at 314-743-8641 or malthage@stmarkstl.com.
