Dave, you and your team are just amazing!  It was a complete pleasure to be with you and your staff at the new Elite Center for the Train-the-Trainer workshop.  Please thank each of them for taking such good care of everyone who attended. 
Both the training and live practice activities were very impactful, and stretched each of us to improve.  I am already making adjustments to my training presentations and materials which will help me to become much more effective in my own responsibilities.
I always pay attention to those on the team in addition to their leader, and what I experienced confirmed to me that yours is indeed a very, very good organization.  I left feeling enthused, motivated, and full of knowledge that will make me better at my job.
