I was unhappy with my overall experience. The person at the front desk was sullen and unfriendly. The doctor treated me like I was overreacting regarding my symptoms. He didn't want to do a specific test but I insisted. The tests he ordered showed nothing but the one I wanted had urgent abnormalities. I've been needing to have them fax an order and they seem unable to get it right. There is no nurse on call for pre-op issues either.

Have waited 2 years to get test results and consultation following my procedure. My last appointment I was in his office from 3-6pm. He entered the room in a business suit saying he had an event to go to and therefore there wasn't any time to talk about my procedure.

Dr. Zimmerman ordered Hepatitis C blood test for colonoscopy & coded test as routine. Result of coding caused my insurance company to deny claim. Maria insurance claims was no help saying she was new & not there when I had my colonoscopy. Next, doctor's nurse, Sandy told me they would NOT change coding & would not explain why the test was ordered. Hep C was an unrelated & erroneous test costing me $139.31. Staff is unprofessional & does not have the patients interest at heart.?

Would never recommend this doctor. Office staff very rude and incompetent. Dr. Zimmerman missed the opportunity to start me on a medication that I finally got on from another top-level physician that made a world of difference. When I experienced significant pain, he said Just go to ER just a very poor experience all around. Indicated incorrect information on history & physical--I had to cross it off and correct for new dr. Staff rude, billing horrible.
