    When meeting with Dr Blash, for the first time, eased my mind about my ongoing care. Dr Tillmon was my primary care physician for years. I’m pleased that Dr Blash took her time asking me questions and then listening to my answers. She was matter-or-fact type of doctor that led me to immediately trust and believe that she a good fit for me going forward.

    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.
