Our People

Director and Missionaries

john-LindaHeaterJohn and Linda Heater have come to TEAMS for Medical Missions from more than 25 years of preparation for and experience in full time ministry. Graduates of Washington Bible College and Capital Bible Seminary (John), they are experienced in preaching, teaching, and are specially trained in counseling. They served in youth ministry in a Washington, DC area church for fifteen years and in the pastorate for several more. They come from a strong missionary background both by family and by experience. They have organized and led many mission teams here in the States and in such overseas places as Moldova, Lithuania, Romania and France.

John and Linda have joined and are leading TEAMS for Medical Missions because they share the TEAMS vision for strong churches in Jamaica. From the home office in Allentown, Pennsylvania and in Jamaica they serve the Lord Jesus first, but then the TEAMS missionary family and the people of Jamaica.

Director Emeritus


Ray Shive and his wife, Ruth came to TEAMS for Medical Missions in mid-2001. Prior to that they were involved in pastoral and teaching ministries in the United States, then for 20 years in cross-cultural missions in South Africa and later in USA home office administration.

Ray and Ruth brought to TEAMS a vision for strong Jamaican churches. This came to mean a year-round ministry with existing churches through on-field missionaries and regular J-Team visits. This ministry emphasis continues to this day.

They retired in June 2014 and Ruth went to be with the Lord in April 2017. Ray continues to serve the Lord in the area of foreign missions but also in other teaching and writing ministries.
