Lily Johnston, MD, MPH, is a board-certified vascular surgeon with clinical and academic interests at the intersection of vascular disease, cardiometabolic risk, preventive care, and health systems. She earned her BA from Princeton University, her MD from the University of California, San Diego, and her MPH from the Johns Hopkins Bloomberg School of Public Health. She completed general surgery residency at the University of Virginia and vascular surgery fellowship at Mayo Clinic. She is also board-certified in obesity medicine.
Dr. Johnston practices vascular surgery at Scripps Clinic in San Diego, where her work spans the full spectrum of vascular disease, with particular interest in peripheral arterial disease, atherosclerotic risk reduction, lipid management, metabolic health and obesity management. In addition to her surgical practice, she is developing a prevention-focused cardiometabolic vascular health program aimed at identifying and treating high-risk patients earlier in the disease course.
Her broader work focuses on translating vascular surgery expertise into upstream prevention, patient education, and systems-level conversations about how medicine can better address preventable cardiovascular disease before it reaches the operating room.
