— Birdeye/Google Review"Be sure to ask questions before hand about billing and charges. They do not always make it clear. Then you are stuck with a large bill you did not expect."
— LocalityBiz Review"I’m giving 5 stars to my doctor and no stars to the clinic. I’ve needed a colonoscopy two years in a row to monitor chronic IBD. Both years, the clinic has overcharged me, with zero communication other than a bill without itemized charges."
