"Mark, you were the hit of the conference. You made such an impact and gave so many people things to think about and ultimately make changes in their lives.  I cannot thank you enough.  Everyone from our receptionist to (our CEO) and the rest of our executive team were completely blown away. You made our conference.  Everyone could see how genuine you were. You were funny, while delivering a very strong message ...  I really look forward to working with you again."

"As this was the 3rd time in 4 years that Mark has been a part of one of our business events, he more than met our expectations. His ability to take our business issues and challenges and wrap a message around it leaves the audience inspired. One sales associate told us, it literally changed his view on work and life. Mark’s presentation is rich with meaning and the humor keeps the people engaged."

"... I have already sent a note to our SVPs ..., our HR person, and my boss about what a wonderful job you did. I told them about how effectively you weaved in my comments ... and how you tied to our mission of "winning the hearts, minds, and wallets or our customers through delivering extraordinary customer care at the right margins". I loved that you emphasized it's not about us spending more money, that it's about outthinking the competition. I shared with them the standing ovation that you received, which I can tell you is rare at American Express. You really did an outstanding job. Many employees told me that you "touched both their hearts and their brains" which is quite a compliment."
