About Safe Environment

The Diocese of Sioux Falls is committed to providing healthy and secure environments so our children may grow safely in their Catholic faith.

To pursue this mission, we have created a safe environment program for all who minister on behalf of or in the name of the Church. Using educational programs designed to provide the knowledge necessary to prevent and recognize abuse, and the Sexual Misconduct Policy of the Catholic Diocese of Sioux Falls to uphold the articles in the Charter for the Protection of Children and Young People, we hope to fulfill our promise to protect our children.
