John and his wife Karla have been missionaries in Mexico since 1985. They have dedicated their lives to promoting a missions revolution and a new leadership culture in Latin America. Through Global Outreach Ministries, they have established Bible training centers to prepare leaders and are currently providing financial support for full time pastors in Latin America. They have also founded Todos Deben de Saber (Everybody Ought to Know), which motivates Latin American youth to become involved in world missions, mobilizing them on short-term mission trips and mentoring them for ministry in the nations of the world.
In 2015 John stepped up during a time of transition for the RLCI organization and took up the honor and responsibilities of being the president of Resurrection Life Churches International.
