Dear JOHN MICHEL,
I offer you my sincere appreciation to you for taking the time to make the presentation to our annual conference last month. The whole conference was a success but most people commented on how outstanding your presentation was. I feel that the overall success of the conference was in a large part down to your talk.
I would consider it an honor if you would agree to attend next year’s conference and undertake another excellent presentation for us. You made this year’s event truly memorable.
