She served as a teacher and librarian in Brooklyn.

Sister Regina later returned to Peekskill and continued as a teacher and librarian in the Good Shepherd House of Studies working with young sisters in the Sisters’ Formation program. She also served in the Good Shepherd educational and job-training programs in Hartford, Conn.; Manhattan and Madonna Heights, Dix Hills, L.I.

She became actively involved in congregational service at Madonna Heights Services until she was missioned to Good Shepherd Center in Marlborough and later, due to ill health, went to St. Patrick’s Manor in Framingham.
