Born in Milwaukee, she entered Sisters of Mercy in Des Plaines in 1948.

For over 50 years, Sister Sharon, whom some may remember as Sister Mary Misael, served in elementary schools in the dioceses of Davenport, Iowa; Rockford, Illinois; and Madison, Wisconsin; as well as the Archdiocese of Chicago. In the archdiocese, she taught in Des Plaines, Chicago, Libertyville, McHenry and Park Ridge, including 10 years at St. Stephen in Des Plaines and 21 years at St. Paul of the Cross, Park Ridge.

After retiring from teaching, Sister Sharon went back to St. Stephen, where she served as a librarian and then as a tutor.
