Dr. Parker told a racist (hispanic) joke to me while I was in the chair with my mouth held open for a root canal. His 'sense of humor' borders on reprehensible. I put up with it for many years because of the inconvenience of changing dentists. But i have changed. Surely the field has more mature and decent dentists. Go to one these, not Dr. Parker.
