Don Mance was born in Albany, New York. He served in the United States Air Force from 1988-1992, in the Netherlands and the Upper Peninsula of Michigan during the end of the Cold War. Shortly after leaving the Air Force in 1992, Don gave his life to Jesus Christ. He has preached in several churches in the Albany area and also done a short term mission to the Dominican Republic. A unique set of circumstances immediately following September 11, 2001 thrust him into a role of spiritual leadership at work. It was this experience that compelled him to write God at Work: Sharing Christ on the Job. Don's latest book, The Great Exchange, is an overview of the spiritual dynamics that result from a decision to live for Christ. In August 2014, The Great Exchange was translated and published in Dutch as De Grote Uitwisseling. Don's wife Mandi is originally from Glasgow, Scotland. They frequently travel there together. Don's other interests include advocacy for veterans' issues and for animals. In 2015, Don and Mandi relocated to the Maine seacoast.
