Brother David and Diane Cato were approved as World Baptist Fellowship missionaries to Brazil in May 2002.   Diane served as a single missionary for four years in Brazil before she and David were married in 1988.  They worked together as missionaries for eight years. After four years of pastoring in the United States, they felt God's call back to service in Brazil.

Brother David was saved at age nine after hearing a sermon on "Hell" at North Highland Baptist Church in Warrior, Alabama, and is a 1987 graduate of Massillon Baptist College. Diane was 14 when she accepted Christ as personal Saviour after hearing the gospel at Memorial Baptist Church in Columbus, Ohio. She is a 1982 a graduate of Massillon Baptist College.

The Catos have three daughters, Sarah, Lori (both attended Heartland Baptist Bible College), and Amber (who is still at home), each of which have professed Christ as their Saviour and serve Him by singing and witnessing for Him. Their sending church is  Community Baptist Church of Pensacola, Florida.
