  • Dr Diaz is awesome, always very patient and knowledgeable about my history and care
    I go out of my way to see Dr Diaz. She's wonderful
    She listened to me
    I highly recommend dr. Diaz to anybody that has health problems or thyroid problems she a great doctor she cares for her patients very much
    It took 2 months to get in for my first appointment and I waited over 40 minutes for her after her nurse checked me in. Not a great first impression. She did spend time with me but at that point I was in a hurry to get to another appointment.
