Don grew up in Osceola, Arkansas, where he came to believe in Jesus Christ as Lord and Savior. He was active in sports throughout high school and college, and worked in the radio station his dad managed.

      After graduating from Arkansas State University, Don planned to finish law school and pursue a career in sportscasting. While at the University of Arkansas School of Law, he sensed God's call to preach the Gospel of Jesus Christ. He then enrolled at Southwestern Baptist Theological Seminary in Fort Worth, Texas, graduating with a Master of Divinity degree in 1979. In 1987, Don completed a Doctor of Ministry degree at Trinity Evangelical Divinity School in Deerfield, Illinois. Currently, he is completing his Doctor of Theology with Specialization in Christian Spirituality at the University of South Africa.

      Prior to his ministry as a seminary professor, Don was pastor of Glenfield Baptist Church in Glen Ellyn, Illinois (a suburb of Chicago), for almost fifteen years. Altogether, he has served local churches in pastoral ministry for twenty-four years. He is the author of several books.
