Mary attended Blessed Sacrament School, Aquinas High School, and the University of Wisconsin- La Crosse for Bachelor and Master degrees in Elementary Education.
Mary taught physical education in Onalaska, WI, from 1963 to 1968. Beginning in 1970, she taught kindergarten at Fauver Hill School, where she had the opportunity to share her love of learning with many young children. Mary later taught third and fourth grades at Northern Hills School until 1995. While there, she received recognition for her work in teaching science and environmental education. After retirement, she continued to work as a substitute teacher in the La Crosse and Onalaska school districts from 1995 to 2013.

Mary and her husband Donald enjoyed traveling and spending time with their family and friends. They were active members of the La Crosse Public Library Friends of the library for many years and volunteered at the Hixon Forest Eco Park. Mary was a member of Mary, Mother of the Church and her home parish, Blessed Sacrament Catholic Church. She was installed in Catholic Daughters on May 12, 2015.
