SCAM ARTISTS. Called numerous times, was told that the doctor would call me…ya think he would call, right? NOPE! On top of that…they lost my bloodwork, lots of he said she said going on…. And now they think I’m paying for this bloodwork? So crazy! Also, his staff is SO absolutely rude that not one of those girls deserve to have a job. Need a gastro? Keep looking… :-/

The staff was great when I went in for my colonoscopy. They took excellent care of me before and after my procedure. I look forward to having them do my next colonoscopy in 10 years.

Dr is very good, takes time to answer questions and help resolve health issues. Hes very soft spoken and seems very kind. But, his staff not so great. I get repetitive notices, hard to talk to receptionist as shes always short with me and the MA’s always seem to hate there’yr job. I’ve also always waited 30 minutes or more to actually see dr which is too me the average for most all my doctors
