    Dr Barrera is the best
    24-Oct-2017
    *Dr. Barrera is awesome. I have recommended him many times.
    18-Oct-2017
    In meeting the provider is very good. KEY problem is LACK OF continuity - if I have a follow up question on concern, it is IMPOSSIBLE to reach him. NO RESPONSE.

    *Dr. Barra. He is a great doctor, it has been one of the best I ever had.
    29-Sep-2017
    Dr. Barrara is probably one of the best doctors I have ever seen. I never feel rushed and feel as though he is really listening to my concerns. doesn't ever feel as if he is on a time schedule, although I know he probably is. I would highly recommend him to anyone. what I really appreciate is that when he is with me he doesn't seem to be thinking of his next appointment , he is present the entire time!!
