    Dr. Casta is very thorough and consistently demonstrates excellent diagnostic skills, professionalism andGenuine patient interest and care. Dr Casta stays on top of my pharmaceutical needs, which can be challenging due to several pharmaceutical allergies & sensitivities.

    Dr. Didn't have much of a personality. I tried to make conversation but no response. All business and didn't feel very comfortable. I will try another Dr. Next time.

    Dr. Casta is pretty quick getting things done. He is "by the book" and goes by numbers more than the individual. There isn't much of a personal connection.

    Sat there while Dr pretty much just looked at my file. Should have done that before hand. Making a longer office visit then necessary.
