Welcome to GastroDiagnostics

GastroDiagnostics was one of the first free-standing endoscopy centers to open in Orange County. We performed our first colonoscopy in 1993 and tens of thousands since then. Our endoscopy center is certified by the Centers for Medicare and Medicaid Services (CMS) and achieved the highest level of accreditation by the Accreditation Association for Ambulatory Health Care (AAAHC). 

Designed exclusively for outpatient endoscopy, we are a state-of-the-art facility that uses the most modern endoscopy equipment available today. Our staff includes experienced Board Certified Gastroenterologists as well as registered nurses and medical technicians professionally trained in endoscopy. We have participated in dozens of clinical research studies including several that were pivotal to bringing many drugs to market including Nexium, Protonix, HUMIRA, Cimzia, Amitiza, and Linzess to name just a few. 

We strive to provide the best outpatient endoscopy experience available. Many of our patients are either repeat patients or friends and family of other patients. Our goal is to provide our patients with a smooth endoscopy experience and achieve the best gastrointestinal health possible for the best price. 

Typically, your out-of-pocket expense for a colonoscopy at a free-standing endoscopy center like GastroDiagnostics is much less than a hospital affiliated center. Compare our lower costs.
