Sister Mary’s first ministry in elementary school education began at St. Anne’s, Garden City, NY. She taught at St. Mary’s School, Long Island City, NY, for a short time before being assigned to Marymount School in Barcelona, Spain, and St. Thomas Aquinas, Bronx, NY.
A major part of Sister Mary’s ministry centered around various forms of art.
While she was studying art at Marymount College, she was a House Director and ran a small shop in the Art Department where art students could buy supplies. She began teaching pottery, crafts, and weaving to adults and in programs for persons with developmental disabilities.
She was a recreational therapist at Howe Avenue Nursing Home and the New Rochelle Nursing Home, both in New Rochelle, NY, and at Andrus On Hudson in Hastings-On-Hudson. She worked at the retirement homes of the Ursuline Sisters in New Rochelle and the Dominican Sisters of Hope in Newburgh, NY, and with the RSHM at Marymount Convent in Tarrytown.
Sister Mary served on the staff at Cormaria Retreat House, Sag Harbor, NY. In addition to her main responsibility for building and grounds, she gave classes in weaving and ran the gift shop. Cormaria provided her many opportunities to pursue her interest in photography, a gift she shared with many.
Sister Mary was associated with the Craftskeller at Marymount College and the RSHM Weaving Center in Tarrytown. She spent many years in these fiber arts centers, weaving and helping others to learn and enjoy the art of weaving.
