  • "Took me in on his day off as a new client when others seemed disinterested in my severe pain issues. He extracted the tooth with precision and displayed enormous professionalism. I was so impressed with him as a dentist and human being that I will never go to another dentist. He was a breathe of fresh of air in a time when doctors appear to have lost their compassion for people who are suffering and need immediate attention. I am truly grateful for the timely care he gave me."
