"Appreciate the role of self understanding and ethics and a plan based on ethics and core values. I appreciate the insight."

"Someone had mistakenly told me that "his writing is better than his presentation." Nothing could be further from the truth! One of the most inspiring and thought generating speakers I have encountered. Reminds me of an academic Tony Robbins (please, that is my frame of compliment!) What better gift to give other than the gift of provoking thought and changes in behavior."

"Excellent. I particularly enjoyed the Mary Kay story and analysis as a leader."

"Stimulating, relevant, inspiring, challenging. If we could all only have a mentor such as John."

"John was excellent, but I was disappointed in the duplication of his material with last winter's program with Gary. Perhaps a solution would be to check rosters for past participants and notify them if duplication will occur. It can then be their choice as to whether they should attend."
