    Dr. Blash never talks down to me. She talks so that I understand exactly what is going on. What I like the most are the little tips on food which is important to me as a diabetic.

    Because she is so kind d. She REALLY listens to me and that is not easy cause I can be exhausting...lol. I was one of Dr. Epstein's first patients and he took very good care of me. When he left I felt a real loss. But I quickly grew to have the same fondness and respect for Dr. Blash.

    I asked for a prescription to alleviate my anxiety about flying. She refused to give me a medication I asked for and never called into the pharmacy the prescription for the one she said she was going to give me. So I never got the prescription before my flights
