“I first heard about Sterling in Glendale, CA through a dentist friend,” says Dr. Dennis McCullough of Waynesboro, Pennsylvania. “I was talking to him at a Christmas party, and he said he was going to give up his dental practice, but then had decided to give Sterling a try.
“Later on, when he had done the Sterling courses, and his practice was doing well, I would ask my friend what Sterling would say about this or that business situation. The answers weren’t the same kind of brush-off answers I thought some other consultant might give. I was impressed.
