St. Mary Catholic School is a community of worship in Christ, open to growth toward fuller humanness through a living faith, hope and love. The goal of this community is to create a Christian environment wherein the child learns to integrate secular knowledge with the life and teaching of Jesus Christ. Achievement of this goal will be best accomplished through mutual warmth and friendliness in an atmosphere of self‑awareness and awareness of others.
