Before coming to West Houston Bible Church, Dr. Dean was the Pastor of Preston City Bible Church in Preston, Connecticut. Prior to that he had served churches in both the Dallas and Houston, Texas areas and has over 35 years of pastoral experience. Dr. Dean is a much sought after Bible teacher both in the United States and overseas.

He serves on the adjunct faculty of Faith Evangelical Seminary and is the Chairman of the Governing Board for Chafer Theological Seminary.

Dr. Dean trained for the ministry at Dallas Theological Seminary where he earned a Th.M. in Hebrew and Old Testament Studies and later returned to pursue a Ph.D. in theological studies with an emphasis in Historical Theology. He also earned an M.A. in Philosophy from the University of St. Thomas (1987) and a Doctor of Ministry degree from Faith Evangelical Seminary (2002).

In 1988 he was recognized as an Outstanding Young Man of America, and in 1989 was listed in the Who's Who in American Christian Leadership. His academic training in Greek, Hebrew, theology, philosophy, and history enables him to study the Bible in the original languages and show how these eternal truths are as vital today as always.
