    I'm very satisfied with *Dr. Maruja Diaz because she always listens to me and is a _____. Very nice and always attentive.
    17-May-2020
    The appointment went quickly, even the doctor was thorough in her explanations.
    20-Mar-2020
    She berated me, seemed angry (controlling anger), because I had not made an appt to see her since it had been around 2 years since I saw her. I just kept getting my refills for thyroid medication. I did not know I was supposed to see her. I don't care for her and would like to find someone I could relate to better. This whole coronavirus situation has kind of thrown a wrench into everything. Once everything clears up I will probably look for a replacement. We definitely don't get along. All the assistants, receptionists were very nice.
