Welcome to Charleston GI

Charleston Gastroenterology Specialists, Charleston Endoscopy Center and Summerville Endoscopy Center are dedicated to the diagnosis, treatment and prevention of diseases affecting the digestive system. Charleston GI’s Open Access Colonoscopy Program allows patients without significant gastrointestinal symptoms or other health risk factors to schedule a colonoscopy without a preliminary visit prior to the procedure. Our practice is the first and largest gastroenterology practice in the lowcountry to operate a physicians’ practice and two nationally certified and state licensed endoscopy centers. Our mission is to provide the highest level of medical care in the field of gastroenterology. We value the health, service, and satisfaction of our patients above all else.

What our patients think

- Patient of Dr. Marsteller

I have had a very difficult time w/ doctor and office staff since I moved to SC. CGI is the BEST Doctor and staff I’ve encountered down here. I recommend you to everyone. I don’t give out Very Goods easily, but you earned it.

-Moncks Corner

I was well pleased with the way things went. Staff was top notch and they should be commended for doing a good job. Dr. Brener is a very good doctor.


I was really afraid to have that procedure. Everyone was so very kind and reassuring. My thanks to your caring staff and Dr. Brener’s expertise.
