Sister of St. Casimir Regina Marie Dubickas, 75, died March 26.

Sister Regina was born in a refugee camp in Schleswig, Germany, after her parents left Lithuania. As a child, she immigrated to the U.S. with her family, who settled in East St. Louis. She made her first profession of vows in 1967 and her perpetual vows in 1972.

Sister Regina ministered in Illinois for 54 years as a teacher, director of formation, psychologist and congregational leader.

In the Archdiocese of Chicago, Sister Regina taught at Immaculate Conception School (44th Street, 1967-1968), Nativity BVM School (1968-1970) and Providence of God School (1970-1973), and she was a guidance counselor at Maria High School (1978-1979). She was formation director for the community from 1978 to 1989. She ministered as a psychologist at Michael Reese Hospital, as well as in private practice, from 1994 to 2006.

In 1998, Sister Regina was elected to congregational leadership, where she served first as general councilor (1998-2003), then as assistant general superior (2003-2013), and, from 2013 until her death, as general superior.
