Select Testimonials

"We had almost 300 people from around the world tune in live for Mike's presentation. We have received extremely good feedback from participants, unsolicited, around his story and message. I think it was a home run or a perfect lift off!"


"I have hired countless speakers to close out large user events and I will say that Mike is one of the best that I have ever hired. Not only is he a down to earth person and easy to talk with, but the message he delivers relates to everyone. Normally when you hire an external speaker to close out an event, there is usually a good size drop-off of people who are trying to catch a flight out of town. Not in our case. I looked around the room when Mike started and it was close to being as crowded as day 1 of the event (roughly 1300 people). Also, afterwards, Mike signed his books for attendees and we estimate that 500+ were in line to get a book signed. I would HIGHLY recommend Mike to anyone who needs a closing guest speaker."


"Mike is so inspiring, motivational, and GENUINE!!! His stories are amazing – I could listen to him all day! It was truly a hit with our audience. Please thank Mike on behalf of the entire team. I hope we get to work together on another event in the future."

"I wanted to thank you for your contribution to our sales meeting… your talk was the highlight of the meeting for all in attendance. It is always great for me to see an individual like yourself with an incredible resume and unique life experiences who is still incredibly humble and down to earth (pardon the pun). You fit in perfectly with our company values. The feedback we got rated higher than anything we did, and it wasn't even close. The message you delivered – the tone of never giving up, team culture, perseverance and overcoming challenges - still resonates this week in conversations."

"Mike was great. He did a fantastic job of engaging the audience with his stories and down-to-earth style (pardon the pun). He hit the mark on our key messages, but didn't beat people over the head with them. He integrated them seamlessly into his stories. I also appreciated that he hung around and chatted with a number of our colleagues after his remarks – even if it did nearly cause him to miss his flight. All told, he was a hit."
