Jean-Marc Gretillat was born in Switzerland and trained as a forest engineer. He became involved with The Navigators at UBC in 1969 and was part of the initial team to Quebec in 1973 where he was first responsible to open the ministry at the University of Sherbrooke.
Subsequently he and his wife Sylvie pioneered the ministry at the University of Montreal. In 1985 he started traveling to Africa and became the Country Opener for Zaire (actual D.R. Congo) and then for Congo Brazzaville. Since 2001 his role is to supervise The Navigator ministry in the Francophone zone of Africa where The Navigators have a ministry in ten countries.
