Warren and Shirley felt the Lord's call to the mission field in Brazil arriving in the city of São Paulo in 1969 with 3 of their children. The following year they moved one state south to Paraná, where they led a Bible study group and worked with the brethren in a leadership training program. Several years later they moved to the city of Araraquara (see map), in the state of São Paulo. There they established a successful church out ofwhich several leaders and workers have come, including son-in-law Bernardo and daughter-in-law Con. After the church was well established they relocated to Rio Claro (see map), 100 km southeast of Araraquara where another church was started. In 2000 another group was formed in Americana (see map), 60 km away. As the work is gradually being taken over by other personnel they have devoted more time to a writing ministry. They oversee the entire work in Brazil while sharing church duties in both Rio Claro and Americana.
