Mary McCarthy

Mary McCarthy, Business Manager   |   Send a message
Mary’s career at St. Mary’s began in 2010 after working in the corporate world for 25 years as a software trainer and consultant. She is a graduate of Boston College and Bentley University. Mary is the youngest of nine children and worked her way through school by juggling multiple jobs. This turned out to be the best training for working at St. Mary’s!

Mary happily notes that she and her husband have been married for 35 years and have two grown children. She says, I love working for the Lord. It’s humbling.
