Presentation Speakers

"Hello Everyone, - I needed to do a lecture on New Decision Therapy. I had not done this lecture in 5 years and was worried that my voice would give out. To my surprise the day went by VERY easy. I talked for six hours and no strain or tiredness! I believe that the class understood the material MUCH BETTER because every nuance of inflection in my voice was faithfully and naturally heard from any spot in the room."
