A U.S. News & World Report Best Ambulatory Surgery Center!
For the second year, our center has been named one of the Best Ambulatory Surgery Centers in the nation by U.S. News & World Report.
I would strongly caution anyone considering this clinic. My mom recently had a colonoscopy here, and during the procedure she experienced a serious complication — her oxygen levels dropped to the point where she had to be woken up in the middle of anesthesia. Given that situation alone, we expected at least some level of follow-up care or concern. The next day, she developed a fever. I called the clinic multiple times, left voicemails, and even responded “yes” to their automated follow-up text indicating she had complications. No one answered. No one called back. Not that day, not the next day — it took an entire week for anyone to respond. In the meantime, her condition worsened. She was later diagnosed by her primary care doctor with pneumonia, along with a swollen neck, swollen lymph nodes, and an ear infection — all following the procedure. If she hadn’t gone to her regular doctor and received antibiotics, this situation could have turned much more serious. What’s most concerning is not just the complication itself, but the complete lack of accountability and follow-up. This clinic was aware there was an issue during the procedure, yet made no effort to check on her afterward or respond when we reached out multiple times. Patient care doesn’t end when the procedure is over. Unfortunately, that’s exactly how it felt here.
