    Dr Bar was wonderful and I finally feel after 3 years confident that my medical issue will get better. He spent time explaining and showing me the condition of my problem. Since I had never met Dr, Bar before, I felt comfortable safe and thankful for his expertise.

    I believe he was very respectful and kind, but I think we're coming from different places and I didn't feel that we were particularly meeting in the middle somewhere. But I felt he was respectful and kind and I don't have a complaint about him. I just don't feel that we were a good match.

    He does listen to his patients. It seems more than other providers that I've seen. I wish you would listen a little more, but he definitely listens more than other providers.
