    *Dr. Adamany called me at home twice during the years he has treated me - I was very impressed!
    Dr. Adamany was very professional and kind. He offered to research alternative treatments for my disease.
    Still undergoing treatment. Condition has not changed or improved.
    Due to computer issues, doctor did not have my records from a procedure 5 years earlier.
    *Dr. Adamany is obviously very smart but too busy to address something acute. VERY dismissive of my concerns & experience (symptoms) (and he admitted it too).
