This provider demanded payment PRIOR to treatment. By the time it was over, I went looking for a malpractice attorney. The only reason I stopped looking was the statute of limitations expired. I filed reports with the state attorney general, the Oklahoma Board of Dentistry and the Better Business Bureau. I recovered some funds by subrogation. Space does not allow full description of what a poor choice I made by choosing this "dentist". For your safety, STAY AWAY.
