    Very nice, explain well
    Dr. Diaz has helped me a great deal. She was instrumental in getting me started on my weight loss journey and is very supportive.
    Dr. Diaz is probably the most conscientous medical person I've ever had. I know she reviews tests, etc immediately as she quickly responds to them with medication changes, remarks, etc. My family is very happy with her as she is very good about contacting them with any concerns. She is a keeper!
    Dr. Diaz is very complete, listens and gives back constructive advise.
    Always easy to talk with and is understanding
