The Gastroenterology Institute of Southern California is different from other gastroenterology centers in Los Angeles. Our private Gi health practice ensures quality over quantity. Our team aims to provide each of our patients quality time with a gastroenterologist and the convenience of laboratory services all in one place. The Gastroenterology Institute of Southern California is led by our double board certified gastroenterologist, Dr. Peyton Berookim.


My first priority in leading a successful practice is giving my patients the expert care they need and deserve. Together we will journey from a preliminary intake at my office. This is a process that includes a detailed history and physical exam to determine what tests, including laboratory tests and imaging, may be needed. Next, we conduct tests with state-of-the-art technology to arrive at a diagnosis and produce an effective treatment plan. A correct diagnosis can mean better quality of life—and oftentimes even a saved life. I am with you all the way. READ MORE >

Dr. Berookim saved my life. I can’t stress that enough. I was admitted to the hospital back in October and my internist referred me to Dr. B. He immediately got me in for testing. – Lauren H.
