    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.

    Dr, Bar was well informed of my history and listened carefully to what I told him about my condition. He took time to think over all the relevant information and came to recommendations that he explained clearly to me.

    Dr. Bar was extremely professional, very courteous, and he really understood what I was going through, helped me understand what my situation was. He spent more time with me than any other physician ever has. I felt extremely comfortable. He is very, very knowledgeable. And I really have not had a better experience with a physician than I did with Dr. Bar. Thank you.
