The Vestry of St. Mary's Church voted to make the school a parish day school, and St. Mary's School became an official entity of St. Mary's Church.
The church added an education wing to the existing church building. The school opened with 100 students in morning and afternoon sessions of preschool through kindergarten.
The school expands further to the property adjacent to the church. In the fall of 1989, St. Mary's welcomed it's first, first-grade class.
