Bring Conversational Evangelism to your church
Dr. David Geisler — NGIM co-founder and co-author of Conversational Evangelism with his father Norm — teaches, trains, and speaks at churches, campuses, and conferences around the world.
Dr. David Geisler
David serves as President of NGIM, which he co-founded with his father to carry the Geisler legacy worldwide. He is an adjunct professor at Southern Evangelical Seminary and Veritas International University, serves on the leadership panel of the IDMC conferences, and is executive producer and co-writer of the award-winning documentary about his father's life.
His passion: helping believers integrate apologetics into everyday witness — the art of pre-evangelism, gracious questions, and cultivating good soil in a skeptical culture.
