You could buy a round trip ticket to Europe and get your teeth cleaned there for the price this guy charges for a routine cleaning and checkup.
Do not expect them to be up front on pricing. They tell you that they will bill your insurance and your portion is quoted at an amount that seems reasonable. Several weeks later you will receive a bill. Your insurance company will reject his obscene charges, and Dr. Williamson then drops the NEW and LARGELY INFLATED BILL in your lap!
Unbelievable con-man masquerading as a dentist!
It seems unreasonable to expect medically ethical treatment from someone so willing to engage in such abhorrent business ethics. I hope this warning will save someone from being financially blind-sided by this cash eating predator.
