David is a graduate of Dallas Theological Seminary (M.A.B.S and Th.M) and Southern Evangelical Seminary (Doc. of Ministries in Apologetics) and has been involved in Church and para-church Ministry for over 30 plus years. David serves as President of Norm Geisler International Ministries, and is an adjunct professor at Southern Evangelical Seminary and Veritas International University, the two schools his father cofounded. He also serves on the leadership panel of Intentional Discipleship Making Conferences (IDMC), founded by Rev. Edmund Chan, and is the executive producer and co-writer for NGIM’s award winning documentary about his father’s life and impact. David is passionate about teaching others how to integrate apologetics into someone’s daily witness based on the book, Conversational Evangelism, that he co-authored with his father as well as his father’s book, Twelve Points That Show Christianity Is True, and I Don’t Have Enough Faith To Be An Atheist. David is also passionate about teaching an integrated approach of “A Certain Kind” of Evangelism, Apologetics, and Discipleship called “Our Walk and Witness” which is also based off of material in his friend’s book, A Certain Kind, by Rev. Edmund Chan. David’s life-long goal is to give to every child of God the gift his father, Norm Geisler, gave him.
