Jack is also survived by his sister Kathy Nicholson, his brother Paul MacKinnon and his wife Gerri, his sister-in-law Nancy MacKinnon, many adored nieces and nephews, foster grandchildren, and too many friends to count. He was predeceased by his parents, Clarence and Catherine MacKinnon, his brother Kevin MacKinnon and nephew Ryan MacKinnon.

Jack was born and raised in Dorchester and was a proud graduate of Boston College High School and Boston College. He could often be found entertaining friends and family at BC football tailgates every fall. All were welcome as Jack never met a stranger. He enjoyed 37 years working as a CPA at Price Waterhouse, where his legendary career is still talked about today. A consummate giver, he was always quick to donate his time, expertise and money to those less fortunate. He has served on the boards of BC High, Catholic Charities, Emmanuel College, Laboure College, Nativity Preparatory School, Notre Dame Academy and Pope St. John XXIII National Seminary. He was also an active member of the Order of Malta and served as President of the Boston College Alumni Association. In 2012, he received the Saint Ignatius of Loyola Medal from BC High for his life-long service to others. Jack lived life to the fullest, a lesson that will continue to be shared by all that love him.
