Mike – thank you so much for presenting today! It was a big success, lots of questions were asked, and people were very interested in learning more. In fact, I had one person tell me they already bought the book within the first 10 minutes and another person ask if you’d be willing to speak at their Meet Up for Milwaukee entrepreneurs!
