St. Mary School

St. Mary School was established in 1914 by the School Sisters of Notre Dame.
Now in our ninetieth year, we continue to provide challenging academic programs rooted in the Catholic tradition for children in Nursery (3 year olds) through Grade 8.
The dedication and strong commitment of the administration, faculty, staff, clergy, and parents to continued growth and quality Catholic education permeates the strong family – centered school community.
Centered in the Word of God and the gift of Jesus in our midst, the mission of St. Mary School is to educate the whole child.
The school's role in leading students toward a life of Gospel values is to work in partnership with parents to foster academic, spiritual, and moral development.
