Gastroenterologists - Greenfield, WI

"He did a colonoscopy and said he took biopsies. Later at the chemo doctor, was told me the biopsies were not useful and they did not get useful data. The sample size was too small and did not show what it was to treat with chemo. Then I was told needed a second colonoscopy and a biopsy to be able to get treated as Dr Khan did not do his job correctly . The hospital and staff seem acceptable to numerous operations , versus holding themselves accountable for the work they do and charge huge sums of money for. They need to do the job right the first time everytime. Never use this doctor unless you want endless colonoscopies and biopsies to get the needed data"
