It is not necessary for David to be introduced before he speaks to an audience, but an introduction can be an appropriate way to set the stage for his presentation. Here are a few intros that David has enjoyed. Feel free to use, adapt or rewrite entirely.
Further Information:
On request, David will send a print brochure that describes his assemblies and workshops for children, along with family programs and professional development sessions. Contact David here (serious inquiries please).
David can also create a customized e-flier to announce his availability in your area. Send David an email to discuss.
