We are pleased to announce that the US News and World Report Best Ambulatory Surgery Center for colonoscopy and endoscopy in Missouri was awarded to Mason Ridge Ambulatory Surgery Center (Gateway Endoscopy Center). This award was based on objective, risk-adjusted measures of patients’ outcomes including avoidance of complications, ER visits, unplanned hospitalizations and other undesirable outcomes. The Best rating is a validation of our efforts to enhance patient safety and to deliver high quality care that you expect. From 2017-2023, our center was given the Pinnacle of Excellence award from Press Ganey for seven straight years. In addition, we received a PERFECT site survey from the Accreditation Association for Ambulatory Health Care in 2022. Though we are proud of these recognitions, our goal is to never compromise so that you will consistently receive the best and safest experience possible.
