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.
