A funeral Mass for Daughter of Charity Sister Patricia Anne Bossle, a former leader of The Seton Keough High School in Baltimore, was offered July 7 at the Basilica of the National Shrine of St. Elizabeth Seton in Emmitsburg. Sister Pat died July 1 at Villa St. Michael in Emmitsburg. She was 86.
Born in Baltimore, Sister Patricia Ann graduated from Seton High School in Baltimore in 1957 and entered the Daughters of Charity April 2, 1958, in Emmitsburg from Blessed Sacrament Parish in Baltimore. She earned her bachelor’s degree in mathematics from St. Joseph College in Emmitsburg (1971), and a master’s degree in institutional administration from University of Notre Dame in South Bend, Ind. (1976).
Early in her ministry, Sister Patricia Anne was a teacher at Mother Seton School in Emmitsburg, later serving as principal and then director of development while also serving as administrator of Seton Center in Emmitsburg. In 1988, Sr. Patricia Anne was appointed treasurer of her religious community’s Emmitsburg Province and served in that role until 1995. As a financial analyst, she served both at DePaul Medical Center in Norfolk, Va., and Western Maryland Health System in Cumberland, Md. (1996-2000).
For the next 10 years, Sister Patricia Anne was on mission at St. Agnes House in Baltimore and served at Marian House in Baltimore as an education coordinator (2000-2003), as director at My Brother’s Keeper Soup Kitchen (2003-2004), and as president of The Seton Keough High School in Baltimore (2004-2010).
While at Seton Keough, Sister Patricia Anne helped launch the school’s “Women in Science” initiative. She also raised funds and oversaw a major renovation of a science wing and the addition of the new biomedical science and engineering. In a 2010 interview with the Catholic Review, Sister Patricia Anne spoke of her strong devotion to St. Elizabeth Ann Seton and her commitment to education.
“I’m convinced,” Sister Patricia Anne said, “that education is the only route out of poverty.”
After leaving Seton Keough, Sister Patricia Ann returned to Emmitsburg and was assigned to special projects of the province. Among her efforts was researching and writing a history of the Eastern Province of the Daughters of Charity 1809-1910. That work was completed in 2025. Sr. Patricia Anne was missioned to Villa St. Michael for the Ministry of Prayer in 2019, a ministry she held until her death.
Elsewhere, she served in New York, Georgia and Virginia.
