Grace Chen Yu
Clinical Associate Professor, Medicine - Primary Care and Population Health
BioDr. Yu is a modern-day version of the “old-fashioned family doc” who delights in caring for patients from “cradle to grave,” while also promoting the health of her community and developing the future leaders of family medicine. On any particular day, one might find her counseling a long-time smoker on quitting, draining an abscess in clinic, delivering a baby, doing a phone (or sometimes home) visit with one of her elderly patients, lecturing about High-Value Health Care, facilitating a diabetes group visit, singing the praises of coordinated primary care to politicians, discussing end-of-life options with a hospitalized patient, or sharing some of her stories as mother-doctor-teacher with one of her advisees. In 2016, adding one more hat to the mix, Dr. Yu became Program Director of the 24-resident Stanford Health Care - O’Connor Hospital Family Medicine Residency Program. Whereas the old-fashioned family doc was a master at caring for patients at different ages and stages of life, as a modern-day family physician, Dr. Yu is committed to researching ways to do so more effectively and efficiently. She considers it a privilege to be a part of her patients' lives and hopes to help both her patients and her trainees find a path to better health and happiness. To keep herself in great health, Dr. Yu enjoys playing the piano, photography, scuba diving, adventure travel (all the more adventurous with her three children in tow!), and spending time with her family and friends.
