Mark & Carole Landis have been involved in ministry since 1955.  After starting several churches in Honduras, they planted three larger churches in Guadalajara, Mexico since 1970.  The Landis’ purchased a property for a camp.  This ministry resulted in campers wanting to learn more from God’s Word.  In 1988 they founded La Roca Bible Institute, developed the property, and have seen over 600 students graduate from the institute.  To this day, Mark & Carole are actively involved in the church, Bible institute and camp in Guadalajara.
