Overview
Dr. Guzman is Chief, Division of Vascular Surgery at Yale New Haven Hospital. He is also Surgeon-in-Chief, Vascular Surgery, Heart and Vascular Center for the Yale New Haven Health System. He came to Yale from Beth Israel Deaconess Medical Center and Harvard Medical School. Prior to moving to Boston, he spent the early portion of his career at Vanderbilt Medical Center in Nashville, Tennessee where he served for several years as Chief of Vascular Surgery at the Nashville VA Hospital. He received his medical degree from the Johns Hopkins University in Baltimore, MD. After completing his residency in general surgery, he undertook research training in the Cardiology Branch of the National Heart, Lung and Blood Institute at the National Institutes of Health in Bethesda, MD and subsequently completed a fellowship in vascular surgery at Stanford University Hospital. He currently serves as a permanent member of the Bioengineering, Technology, and Surgical Sciences Study Section of the NIH. His clinical interests relate to patients with diabetic vascular disease and ischemic foot ulcers. His research focuses on the role of arterial calcification in lower extremity ischemia.
