OC Ministries is Operation Classroom, Operation Clinic and Operation Church rolled into one! OC Ministries is a non-profit mission of the United Methodist Church in Minnesota ministering to the minds, bodies and spirits of children in developing countries. Operation Classroom was founded in 1989 to assist in the rebuilding of UMC related schools in Liberia and Sierra Leone, West Africa. In 1992, Jamaica was added to the list of OC countries. New partnerships developed with clinics and churches and Operation Classroom expanded into OC Ministries in 2000. OC Ministries is an Advance Special of the Minnesota Untied Methodist Annual Conference.
