She also served as director of youth retreats and director of young adults ministry for the Diocese of Columbus. She was a professor of pastoral ministry at Pontifical College Josphinum in Columbus.

Among other assignments, Sister Geraldine taught at Charleston Catholic High School in Charleston, W.Va., and was director of campus ministry and vice president of student affairs at St. Leo College in Dade City, Fla.

Sister Geraldine returned to Stella Niagara in 1995, where she was a provincial councilor for the Sisters of St. Francis, a home health visitor with Mercy Home Health Care and a director of the Warde Center of Buffalo.

She retired at Stella Niagara in August 2009.
