What People Say About Dr. Christopher Duncan, MD
This doctor does not know what he is doing. I went to him for a colonoscopy procedure and he almost killed me by giving me too much fentanyl & not enough anesthesia. I woke up during the surgery & he had the nerve to ask me if it hurt. I will not disclose the details here but because of him not knowing what he was doing ,I almost went into cardiac arrest. You better believe I am going to sue him for Medical Negligence/Anesthesia Error etc. The staff was very cold , rude & uncaring.
