David is available to speak to high school, college groups or churches. When scheduling an engagement, groups can select a specific area (Creation or Dinosaurs or Noah’s Ark) for presentation, or defer to the speaker. Each engagement should plan for a minimum of forty-five minutes to an hour of available time. Full-length seminars in the Southern California area can be scheduled for evenings (either consecutive or once/week) and should plan on six to eight weeks for a full presentation. Full-length seminars in other areas should be scheduled for a weekend with at least six to eight hours available.
