About
Dr. Lisa Maxwell trained at Robert Wood Johnson Medical School and completed her Family Medicine residency at Crozer-Keystone Family Medicine. She then finished a one-year fellowship at ChristianaCare and later earned a Master's degree in Health Care Delivery Science from Dartmouth College. Those credentials tell part of her story. The fuller picture spans 19 years at ChristianaCare, where she served as residency program director, Chief Learning Officer, Chief Transformation Officer, and President of the ChristianaCare Medical Group.
Early in her training, she chose family medicine despite pressure from her medical school to pursue other specialties. A single moment crystallized that choice: watching a family physician ask an elderly patient about her craft show and receive a crocheted animal in return. That exchange showed her what medicine at its best looks like. Dr. Maxwell is passionate about primary care, preventive medicine, and redesigning how care reaches patients. She holds board certification in Family Medicine and treats conditions including hypertension, diabetes, thyroid disorders, depression, anxiety, obesity, PCOS, and metabolic syndrome, among others. She and her husband, also a family physician in Delaware, are raising four sons.
