I had a root canal on a wisdom tooth done at his office. The quality of his work was excellent. However, I found the receptionist to be rather cold. She called me for an appointment and when I called her back a few hours later, she had given my appointment time away. In addition, I felt very lightheaded and woosy after the procedure and the office staff let me leave (and drive) when I should have told to stay in the waiting room until I felt OK to drive.
