About Me

Wei Feng, M.D., is a board-certified endocrinologist and assistant clinical professor at City of Hope® Cancer Center Duarte. Dr. Feng brings decades of experience and a compassionate, patient-first approach to treating complex endocrine conditions, including diabetes, thyroid disorders, osteoporosis, polycystic ovary syndrome, obesity and adrenal and pituitary diseases. 

Originally from China, Dr. Feng earned her medical degree at the University of Heidelberg in Germany, then completed her internal medicine residency at the University of Memphis in Tennessee and an endocrinology fellowship at Cedars-Sinai Medical Center in New York City. Her early career included a hospitalist role at Memphis Regional Medical Center and a faculty position in general internal medicine at the University of Southern California in Los Angeles. 

Dr. Feng’s commitment to advancing treatment options for people living with diabetes goes beyond the clinic. She has served as principal investigator for several key clinical trials focused on improving outcomes for high-risk diabetic patients. Her research has explored cardiovascular health, managing diabetic peripheral neuropathy, supporting islet cell transplantation and exploring novel therapies for type 1 and type 2 diabetes. 

Through her longstanding work at City of Hope, Dr. Feng has helped countless patients lead healthier lives—and her ongoing research continues to shape the future of diabetes care.

Patient reviews
The patient ratings and comments on this page are obtained from an external Press Ganey® outpatient survey provided to all eligible City of Hope patients within one to two weeks of their treatment occurrence. Raw data from the answers to the survey questions about our physicians are calculated by Press Ganey into a one- to five- star rating. In the spirit of transparency, all patient comments are posted as written by the patient, whether they are positive or negative. We only exclude comments if they are deemed to be slanderous or libelous, contain profanity or vulgar language, or do not relate to the patient's experience with the doctor involved. As a result, the comments are the views and opinions of the patients surveyed and are not endorsed by, and may not necessarily reflect the opinion of, City of Hope.
