About
Dr. Cornelia Willis is a board-certified Internal Medicine and Obesity Medicine physician with nearly a decade of clinical experience. She earned her MD from the University of Vermont in 2016 and her Master of Public Health from George Washington University. After graduating, she commissioned into the US Army and completed her Internal Medicine residency at Madigan Army Medical Center in 2019.
Her military career took her from Ft. Drum to a combat deployment in Kandahar, Afghanistan, during the height of the COVID-19 pandemic. She later joined the 173rd Airborne Brigade in Italy, where she ran a soldier-centered medical home and trained combat medics. Those years of service deepened her commitment to affordable, trustworthy care for patients who struggle to access it. After her military service, she and her family settled in Colorado Springs. Dr. Willis practices wholistic, evidence-based medicine, focusing on the full person rather than isolated diagnoses. Her clinical interests span chronic disease, metabolic health, women's health, mental wellness, and geriatric care. Outside the clinic, she is a former US National Team Rower, an avid mountain biker and skier, and a wife and mother who loves spending time outdoors with her family.
