The Atrium is a specially prepared environment at St Catherine Laboure where children experience God as part of the Catechesis of the Good Shepherd (CGS) program. CGS is a worldwide Montessori-based religious education program where children deepen their relationship with God through prayer and work with hands on materials devoted to the most essential elements of our faith, most particularly through Scripture and liturgy.

Students at St. Catherine Laboure in grades K through 4 attend the atrium once or twice a week.
