Sister Ann Pairn entered religious life from her home parish in St. Louis, Mo. Her ministry has included serving on the Provincial Council both in St. Louis and Pittsburgh (1997–01; 07–11). She was the chaplain at St. Louis University Hospital (2001–03), and was a home caregiver for CSJ Care, a home services provider for the elderly, in St. Louis (2003–06). When her term on Council ended in 2011, she returned to CSJ Care in St. Louis, where she has been a home caregiver since.
Sister Ann was also responsible for coordinating the two moves of the provincial offices in St. Louis, as well as the move of the Sisters’ sponsored ministry Room at the Inn. She also coordinated the renovation of Providence Center, and she served on the committee that coordinated the restructuring of the Congregation’s three provinces into the Marie de la Roche Province.
