"Dr. Michael Dempsey, should be avoided at all costs! His "bed-side-manner'" is appallingly stoic, he talked to me like I was "a stray Cat run over by a car and was annoyed to see me!""

"It has been many days since my post of overall neglect and disregard of my health. NOT ONE WORD from Dr. Dempsey. Nothing, no phone call, e-mail, text.. nothing! I am prepared for his defense, and to my embarrassment, he humiliates me with unnecessary questions about the amount of Champagne I enjoy at events that are none of his business..So..DR, If someone was in a car crash, would he refuse treatment because the patient had Champagne in their system? He needs to retire and now!!"

"The Callous BASTARD! I have suffered a life time of UTI's (Urinary Track Infections) so I know when it's going to develop into an infection with excruciating pain to follow. Urinating begins to BURN! Time is of the essence before it becomes so unbearable you can't see straight with pain. Immediately, I called his office to get an instant refill of phenazopyridine and antibiotics he... REFUSED! told me to make an appointment, he just couldn't see me today. He doesn't give a DAMN from a patient who has had him as my Doctor for decades. NOW, TO MY HORROR, I HAVE TO GO TO THE EMERGENCY ROOM AND WAIT, WAIT and WAIT with urination getting more and more painful. I have demanded all my medical files in order to get a Doctor who will GIVE A DAMN! Don't walk away from this heartless Doctor...RUN!!!! "
