“Our people have had a lot of different training classes, but this one is different. The six principles of influence appear to be simple, but the more we learned, the more we realized that this course is really a tight little system that allows us to think in different ways. This Principles of Persuasion course was excellent for our Senior Managers, customer service directors, and salespeople. We saw a measurable difference right away. The only problem is, now the word has spread and everyone wants it.”
