I have retained John over the past few years to give two keynote addresses. The first of these was to the University of Tennessee Supply Chain Forum, and the second was to the Supply Chain Executive Forum at the Georgia Institute of Technology. In both instances, John provided a superb presentation and discussion, and his involvement received very high marks from those in attendance.
Overall, I would say that John is exceptionally knowledgeable and very well-received by groups and audiences. While his presentations always are well-structured and effectively delivered, he is very adaptable in terms of "reading" audiences and modifying his approach to more effectively connect with groups to whom he is speaking. I would consider John to be a very excellent choice for a keynote speaker role for groups of all sizes, as well as a very effective presenter for groups that desire delivery plus discussion.
I have had the opportunity to hear numerous speakers and presenters over the years, and I would definitely put John Mariotti in the upper ten percent of those whom I have heard. His messages are always complete and well-documented, as well as being interesting and enjoyable to hear. He goes over very well with audiences of all types, and I highly recommend him.
