    I have one word for this doctor, RETIRE. I went for follow up appointment after a colonoscopy and he said he might have to go back in and take another look. WOW! He is dangerous and does not care about his patients. Go to St Louis to a real Doctor.

    Dr. Feldman is a good Doctor but the staff is very poor. Often do not return phone calls, if they return them at all. Wait time in waiting room is never less than 2 hours. I once waiting over 3 hours, only to find out (at my insistance) that the person I was waiting to see wasn't even there. It is apparent that the staff does not care about the patient's time or concerns.

    Dr Feldman misdiagnosed me with Crohn's disease and billed my insurance for over $100,000. I later found out he also told two other acquaintances that they had this condition as well. Be careful! He thinks everyone has crohns or is in cahoots with the drug companies!

    Waited over 2 hours with no explanation! Spent 10 min with Dr. Terrible customer service. Stop overbooking! Call patients to inform them of the long wait.
