 Trustindex verifies that the original source of the review is Google. Dr. Fenigstein had to perform a few procedures for dental issues that came up. I was full of anxiety do to the situation. He made me feel relaxed and trusting in his talented ability.  I especially enjoyed his music choices that served as a distraction.  The total environment along with his capable assistant, Theresa made time in the chair move along. I didn't feel anything, but relief.
