Ralph Winter, Ph.D.

After serving ten years as a missionary among Mayan Indians in the highlands of Guatemala, Ralph D. Winter was called to be a Professor of Missions at the School of World Mission at Fuller Theological Seminary.

Ten years later he and his wife, Roberta, founded a mission society called the Frontier Mission Fellowship (FMF) in Pasadena, California. This in turn spawned the U.S. Center for World Mission and the William Carey International University, both of which serve other missions working at the frontiers of mission. He is the General Director of the Frontier Mission Fellowship.
