Duperreault is currently based in the New York City area. He and his wife Nancy have three adult sons. He is the godfather of actress Elizabeth Tulloch.

He credits his career success to his spirituality and his Jesuit education at Saint Joseph’s University.{{cite news |last1=Johnson |first1=Wendy Davis |title=Faith is my inspiration, says Duperreault on retirement from Marsh |url=http://www.royalgazette.com/article/20130116/BUSINESS04/701169964 |accessdate=June 30, 2019 |work=The Royal Gazette |date=January 16, 2013}} A devout Catholic, he has said of his faith, "It’s everything. It’s the essence of who I am. I try to pray for guidance all the time. It’s the best counsel you can seek." Duperreault claims the impact of his faith was most apparent when he was offered the opportunity to rehabilitate Marsh & McLennan Companies, which had been suffering organizational and financial woes.
