The Nightingale-Conant Corporation, in cooperation with Sandler Systems Incorporated, is proud to present The Ultimate Sandler Sales Library - featuring legendary and historic recordings from the one and only David H. Sandler - the founder of the Sandler Selling System. 

David Sandler was a true revolutionary who was far ahead of his time. Back in 1966, something was wrong with the way selling was being taught, and David Sandler knew it. He was a struggling, young salesman who was troubled by the forced, rote way in which he had been trained to sell. It didn’t feel right, and what's more, it didn't work. 

So on his own, he decided to take charge of his sales calls. He started by making “verbal contracts” with his prospects - effectively challenging them to convince him to sell rather than trying to convince them to buy. His approach was radical. Unorthodox. Non-traditional. And dramatically effective. 

Sandler refined his sales philosophy into a comprehensive selling system, and founded the Sandler organization to share his unique approach with other sales professionals. Since his revolutionary methodology was founded on basic principles of the psychology of human behavior, it has stood the test of time. The current proof of their ongoing success lies in the success of tens of thousands of their clients, whose lives and careers are transformed every year. 

What David Sandler developed in the late 1960s, and expanded into a franchising operation in the 1980s, has now grown and developed into it’s current company name Sandler Training - an organization with a rich history that dominates the global training market, with more than 250 offices worldwide, providing instruction in 27 languages. 

While David Sandler passed away in 1995, his legacy lives on through the national entrepreneurial network of Sandler trainers and consultants who continue to deliver exceptional training to the marketplace.
