Dr. Anahita Dua is an Associate Professor of Surgery at Massachusetts General Hospital and Harvard Medical School, where she serves as Director of the Peripheral Artery Disease Center, Clinical Director of Vascular Surgery Research, and Director of the vascular surgery sub-internship. She founded and leads the Limb Evaluation and Amputation Program (LEAP) and established the country's only comprehensive vascular surgery clinic for patients experiencing homelessness, both at MGH. Double board-certified in vascular surgery and general surgery, and board-certified in advanced wound care, Dr. Dua completed her vascular surgery fellowship at Stanford University, her general surgery residency at the Medical College of Wisconsin, and medical school in the United Kingdom. She also holds a master's degree in trauma sciences, an MBA in healthcare management, and certificates in health economics and outcomes research and in AI in healthcare from MIT. Her work focuses on limb preservation and peripheral artery disease, advancing vascular care through research, program development, and a commitment to reaching patients who are too often left out of the health system. Through initiatives like LEAP and her vascular clinic for patients experiencing homelessness, she has built models for delivering high-quality specialty care to under-resourced populations.
