Sister Mary McCormack, S.S.N.D., 92, who taught school for 34 years in New York state and Massachusetts and spent another three decades in administrative ministries, died Oct. 14 at Lourdes Health Care Center, Wilton, Conn. She had been a professed member of the School Sisters of Notre Dame for 72 years.

Born in Massachusetts, her assignments in the Brooklyn Diocese included St. Saviour’s elementary school, Park Slope, 1943-52; St. Mary’s School, East Islip, L.I., 1952-56; and St. Patrick, Glen Cove, 1956.

In 1974, she left teaching to begin ministering to the elderly sisters at Villa Notre Dame, the former S.S.N.D. motherhouse in Wilton. She also worked in the Medical Records Office of Lourdes Health Care Center for seven years and as a member of the finance office staff of the Notre Dame Child Development Center.

In 2002, when the child care center closed, Sister Mary retired to prayer and presence at Villa Notre Dame.

She is survived by her only sibling, Sister Marie Elena, S.S.N.D., also of Villa Notre Dame in Wilton.

Burial was at St. Mary Cemetery in Bethel, Conn.
