Biography

Dr. Yi JennyZheng M.D., Ph.D.

As a diplomate of the American Board of Internal Medicine as well as the American Board of Gastroenterology, Dr. Zheng is double board certified in Gastroenterology & Hepatology, as well as Internal Medicine.

Dr. Zheng's expertise in Gastroenterology and Hepatology developed during her time at USC, where she trained with world-renowned faculty like Dr. Loren Laine, President of the AGA (American Gastroenterology Association), and Dr. Neil Kaplowitz, past president of AASLD (American Association for the Study of Liver Disease), and author of the Textbook of Gastroenterology.

After ten years at Kaiser Permanente, the opportunity to work with a wide variety of patients from all backgrounds is what inspired Dr. Zheng to open her own practice.

As a firm believer in prevention, the focus of Dr. Zheng's practice is colon cancer/polyp screening, Barrett's esophagus, esophageal cancer screening and stomach cancer screening, as well as screening and prevention of fatty liver and cirrhosis.

Understanding that chronic digestive disease can severely impact a patient's ability to enjoy life, Dr. Zheng also makes forming close relationships with her patients a priority.

Dr. Zheng collaborates closely with referring primary care providers as well as colleagues from other specialties like endocrinologists, surgeons, oncologists and radiologists to support patients with complex conditions.
