Greg Trull

Dean of Ministries, Professor of Biblical Studies

Ministry today requires leaders to be effective in communication, understanding of culture, innovative yet biblical in philosophy. The challenges and opportunities in communication and connecting today are incredible. For that reason, we will provide training in formal (preaching and teaching) as well as interpersonal communication. We will also include ministry leadership, business, church growth strategy, cross-cultural ministry and counseling courses designed to address the needs of churches today.

Professional: Dr. Trull teaches Old Testament, Bible interpretation and homiletics and serves as Dean of the School of Ministry. He co-leads study tours to Israel and Egypt with Dr. Tim Anderson and leads Corban’s Bible certificate training program for pastors in Cameroon, West Africa.
