Sister Teresa was born in Milford, Massachusetts, to Loretta and William Byrne in 1931. After earning a bachelor’s degree from the College of New Rochelle and a master’s degree from The Catholic University of America, Sister Teresa began a 15-year ministry in education as a teacher and principal at the Bethesda Ursuline Academy, St. Angela’s, the Ursuline School, and Our Lady of Mercy, and as education director for the province.

In the mid-1970s, Sister Teresa served as superior of St. Teresa’s and St. Angela’s convents and was later elected provincial of the Eastern Province. She spent 20 years in New York State’s “North Country” and was one of the last remaining sisters at the Malone convent when it closed in 2016.

While in the North Country, Sister Teresa was a pastoral associate at St. Michael’s, All Saints, and St. Patrick’s churches. In addition, she served as coordinator of the Malone and Witherbee Ursuline Associates and as the community coordinator for ComLinks, the Community Action Agency of Franklin County.

Sister Teresa provided leadership to the Ursuline Community and numerous boards, including the College of New Rochelle and Angela House. She served the Diocese of Ogdensburg, as a member of Catholic Charities, the Oneness in Peace Center, the Formation for Ministry Board, and the North Franklin Ministerial Association.
