It should be known, David Vaughan DDS dropped my two children and myself as patients because I disputed an invoice stating David had filled three surface cavities, when I was notified of only one and had given consent for only that one surface cavity to be filled. His receptionist's relayed the message, "Dr. Vaughan says he will credit you for the two fillings but we will no longer schedule your family for visits. You may pay the original balance and remain patients, it's your choice." I called the insurance company and he has been paid by them. What worries me, is he does not have to pay that back to the insurance company, even though he did not have permission to render the services. David can do what he wants inside a minor's mouth, bill the insurance company, receive payment and when the parent disputes, he drops the family as patients. Bad business. I was shocked. I've been his patient for about ten years. I'm extremely disappointed.
