CSA takes a comprehensive and collaborative approach to healthcare. Our physicians specialize in all aspects of gastroenterology, and we work closely with other specialists — including primary care physicians, surgeons, oncologists and radiologists — to create an individualized care plan just for you. In addition to our outpatient services, our physicians have privileges at most major hospitals in San Antonio and will continue to care for you if you’ve been hospitalized.

We offer a wide range of support services to elevate our standard of care and satisfy the unique needs of people with digestive disorders. Also, in addition to our vast array of services at GCSA, we can help you access the forefront of digestive care through promising clinical studies.

In an effort to provide you with the highest quality healthcare, our practice continually monitors and analyzes our colonoscopy performance against several national standards. We also conduct regular patient satisfaction surveys at each of our locations. This ongoing process helps us provide exceptional digestive care and identify areas that need improvement.

Below are a few of the quality indicators that we measure on a daily basis. We are proud to report that we consistently exceed the national standard on all measurements.
