I waited an hour and a half for my appointment. When I went up to the receptionist to ask what was going on, the office door swung open and the Dr. Kirzhner stood in his street clothes. I broached my question to him. He told me he couldn't see me, because he had to pick up his son from school. I looked at him, looked at the receptionist and calmly asked for my records. I wasn't about to put my mouth in the hands of someone so unprofessional. He proceeded to yell at me! Not only the worst dentist I have ever been to, but the most obnoxious man I have ever met.
