What Clients Say About The WinFluence® Expert On Customer Service & Sales


Dr. Dennis Rosen is the consummate professional and will 'out-perform' even the highest expectations as a speaker for your meeting, conference or event...  We booked Dr. Rosen as the opening speaker on the final day of (our) event, and we could not have been happier with the results.  Dr. Rosen exceeded our expectations in every way.  He tied his presentation into all the others at the event and provided excellent value...  I would highly recommend using Dr. Rosen for your next conference, meeting or training session.


He successfully touched on issues and solutions that benefitted our entire group.  Additionally, he was able to actively engage the audience by using hilarious stories, interactive examples, and thought-provoking examples...  We strongly endorse Dr. Rosen for any group in need of a dynamic, engaging speaker who brings both the substance and the flash.
