Born in Toronto in 1953, David attended the Royal Military College of Canada and graduated with a Bachelors in Chemical Engineering. After ten years in the Canadian Armed Forces, David retired as a Captain and went to work in Papua New Guinea as a volunteer government engineer. There he met and married Marilyn, an Australian missionary Bible teacher.
Together, David and Marilyn served as missionaries at the Christian Leaders’ Training College, an interdenominational Bible College serving the churches of the South Pacific Islands. David was the Dean of Distance Theological Education. In this role, David and Marilyn wrote several Theological Education by Extension courses. During their twenty-five years in Papua New Guinea they developed a passion for prayer, revival and missions supported by sound Biblical teaching.
After returning to Australia, David served as a full-time volunteer prayer coordinator and writer with the Canberra Declaration, and a member of the National Day of Prayer and Fasting organising team. David and Marilyn have three daughters, all born in Papua New Guinea; and eight grandchildren, all born in Australia. David became an Australian citizen in 2007 and enjoys playing hymns on the bagpipes.
