Missionary Gospel Fellowship began in 1939 from the vision of Paul J. Pietsch, a former Federal Probation Officer, who found an unfilled need in bringing Jesus Christ to migrant farm laborers arriving in California from dust bowl states.

Mr. Pietsch and five Christian businessmen incorporated MGF on October 27, 1942, organizing the work as an independent, non-denominational mission.

In the years since incorporation, as the ethnicity of migrant farm workers changed, MGF workers have reached many other peoples. MGF missionaries are bringing Christ to Hispanics, Asiatics, West Indians, plus Native Americans, isolated rural populations, cults, and inner city ethnic groups.
