“I am so impressed with all the hard work everybody put into putting this program together. All the lectures started right on time, there was no confusion about where to go and how to meet for the sessions. Most sessions were on one floor which made it so easy to get around. Everything was very well done. I congratulate all of you who participated in putting this wonderful conference together. Job well done, and I learned so much! I thank you for that. See you next year!”
