In 1954, 29 acres of land was purchased for St. Mary’s Grade School at a cost of $35,000.00. In the fall of 1955 St. Mary’s Grade School opened with 225 students, 5 classrooms and 5 teachers at a cost of $225,000.00. Sister Myra Joseph was the first principal of the grade school. The other teachers were Sr. M. Claude, Sr. Charles Marie, Sr. Stella Marie and Mrs. Ellen David.
