St. Mary Catholic School serves children from St. Mary's, St. Peter's and Our Lady of Peace in Greeley and Our Lady of the Valley in Windsor by providing a Catholic education in northern Colorado.

St. Mary Catholic School is committed to faith development through a strong emphasis on gospel values. Community service enables our children to learn the importance of serving in Christ's love.

St. Mary is a K-8 school that is part of The Archdiocese of Denver. Catholic Schools are an investment in the future of our children and our Catholic faith. Unsurpassed academic achievement, along with the reinforcement of Catholic faith and formation, provides a solid foundation for personal success.
