Our Staff

Without question, the best and most cherished asset of The Urban Ministry Institute is its staff. Since its founding, the Institute has only employed full time urban missionaries on its staff. All of the various roles and tasks of its workers--from administration and informational technologies, to desktopping and wordprocessing--are staffed by full time missionaries with World Impact, all of whom have spent significant time in ministry in urban communities. God truly has blessed TUMI National with a remarkable group of dedicated and gifted Christian workers, whose sacrifice and service make our wide array of goods and services possible.
