    While it was clear Dr. Zacur was very knowledgeable, he was incredibly condescending and made my husband and I feel even more vulnerable regarding an already sensitive topic. While we got the information we needed, we left the appt feeling so discouraged.

    The provider was not my primary provider at that practice. They were cold, short, didn't seem to listen to me or care what I had to say. I would be happy to never see that particular again. However, I am happy with my primary provider at the practice.
