Mary MacKinnon

Mary MacKinnon’s connection to Hope Floats is deeply personal — born from the losses of Michael Brack and her brother, Peter (P.J.) Shaughnessy. That experience shapes the care and commitment she brings to the board, which she joined in 2025.

Mary serves as Finance Director for the Town of Duxbury, where she oversees a $100 million operating budget. Her career spans decades of municipal finance and technology work across both public and private sectors, giving her a broad perspective on organizational leadership.

A graduate of the University of New Hampshire and a lifelong South Shore resident, Mary lives in Kingston with her husband and two sons. She has long been active in her community, contributing to boards including the Finance Committee, Capital Planning Committee, Community Preservation Committee, and Technology Committee.

She brings to Hope Floats what she brings everywhere: an investment in the people around her and the communities they call home.
