    *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).
    The doctor worked through lunch on his birthday to get me in. - EXCEPTIONAL!
    Dr Adamany is a first class individual and health care provider
    I like that the doctor is direct, decisive and clear. It is obvious that he has a lot of experience and knowledge.
    *Dr. Adamany was great recommend to family.
