She teamed with Barry T. Hynes to create the Paraclete Foundation to provide educational enrichment for at-risk children in South Boston.
The Paraclete Academy provides after school enrichment programs in the South Boston community that aims to erase the education disparity between inner city children and their more affluent peers.
By Sister Ann's retirement as executive director in 2012, nearly 1,000 local children had participated in the Paraclete Academy's programs and over 70 young college graduates had volunteered as full-time teachers in residence.
After graduation from the University of Michigan, where she had converted to Catholicism, she moved to New York City in 1955 which at the time was a center of Catholic intellectual life and social activism.
The order focused on serving the poor, offering Sister Ann the perfect opportunity to combine her two great passions: Catholicism and social activism.
At the time she was in Boston heading a social work clinic in the now closed Nazareth Home for Children which was a mission of the Daughters of Charity.
Sister Ann led and participated in numerous non-profits in Boston, beginning with the Nazareth Childcare Center in Jamaica Plain from 1966 through 1969.
While attending the first gathering of Women Waging Peace, Sister Ann met Aloisea Inyumba, who was then governor of one of the poorest areas in Rwanda, Kigali-Ngali province, whose Tutsi population was decimated in the 1994 Rwandan genocide.
