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.

He attended Wheaton College and Wheaton Graduate School, and graduated summa cum laude in both his B.A. (1988) and M.A. (1989) degrees, in Biblical Studies and Systematic Theology respectively. He earned his Ph.D. in Religion (Theology and Ethics) from the University of Iowa School of Religion (2000). Don and his wife Beth joined staff in the fall of 1975, having served as community minister, as Director of World Impact Wichita, and as Vice President of Education. He has also served in pastoral ministries, as church planter, as associate pastor, and lead pastor.

In addition to his current duties as the Institute’s Director and as professor in its Hope School of Ministry, Dr. Davis also serves as World Impact’s Senior Vice President of Church and Leadership Development.

He has authored a number of books, curricula, and study materials to equip urban leaders, including the Capstone Curriculum, TUMI's premiere 16 module distance education seminary instruction. One of his latest books, Sacred Roots: A Primer On Retrieving the Great Tradition, focuses on how urban churches can be renewed through a rediscovery of the historic orthodox faith. Dr. Davis has participated in academic lectureships such as the Staley Lecture series, renewal conferences like the Promise Keepers rallies, and theological consortiums like the University of Virginia Lived Theology Project Series. Don received the Distinguished Alumni Fellow Award from the University of Iowa College of Liberal Arts and Sciences in 2009. He is also a member of the Society of Biblical Literature, and the American Academy of Religion.

Don has been married to Elizabeth (Beth) since February 1975. Their oldest son, Matthew David, was 26 years old when he went home to be with the Lord in August of 2003.
