Serge (formerly World Harvest Mission) was organized under the leadership of Dr. Jack Miller, a pastor, evangelist and author. In the late 1970s, the missions-outreach of the congregation he founded and pastored, New Life Presbyterian Church, was spreading beyond that local body.
Other church leaders gathered with Dr. Miller to work together in wider ministry. After many informal missions trips to Ireland and Uganda, Serge was officially established in 1983.
Bob Osborne was appointed as executive director of the mission in June of 2005. Today, Serge has nearly 300 missionaries serving in Asia, Africa, Europe, and Latin America.
In 2014, after prayerful and strategic consideration, World Harvest Mission was renamed Serge.
Serge is a nondenominational international mission agency, founded in the reformed theological tradition. As a faith mission, Serge receives no assurance of funds from any source.
