Sylvester Okango began Kenya Evangelism Team in 1972 with one church. He now oversees more than 350 churches with more than 700 pastors, evangelists and missionaries, who lead tens of thousands of believers. KET concentrates on reaching those who have never had exposure to the gospel. Missionaries are very poor, going into the most remote rural areas to reach different tribes, such as the Turkana, Bukusu and Teso.
