Teisa Nicole (Miller) radically committed her life to Jesus as a teenager and also received His call to the nations. After eight years of home missions ministry with Teen Challenge (TN) and School of Urban Missions (New Orleans), Teisa received a word from God about moving to southern Africa. Teisa joined Iris Global (under the leadership of Heidi and Rolland Baker), serving for several years before meeting Jean and getting married on the field.
For 10 years, Jean and Teisa served as base directors for Iris Global base in White River/ Nelspruit area of South Africa. The base consisted of ever-expanding ministries that include the Harvest Bible College, Village of Hope- a community outreach center with various ministries like a preschool, feeding program, Dignity (human-trafficking ministry) and 24/7 Prayer Center, and Michaels Childrens Village (MCV). They pioneered Michaels Childrens Village (MCV)- a family-based, sustainable residential center dedicated to transforming orphaned/abused children into sons and daughters of the King.
