Dr. Ferenc Nagy is a board-certified vascular surgeon with Norton Vascular Associates. As a vascular surgeon, he manages all conditions related or artery and vein disease. Dr. Nagy has always wanted to be a doctor and was a first generation college graduate. After high school he volunteered in hospitals and he wanted to utilize his knowledge to help people. He also is a first generation American, born and raised in southeast Michigan. Dr. Nagy went to college at Michigan State University and medical school at Wayne State University in Detroit. He and his wife wanted to move to Louisville immediately after fellowship after their first visit to build their family. Dr. Nagy treats a variety of conditions including artery aneurysms (like AAA), artery blockages in the neck (carotid artery) and legs (PAD), and treatment for dialysis access. He also treats vein disease such as varicose veins and leg swelling. As a Vascular Surgeon, Dr. Nagy is trained to be able to treat people in many different ways, including performing minimally invasive procedures such as stents for artery aneurysms and leg blockages and opening narrowing with balloons, while also being able to do surgical operations such as leg bypasses, carotid endarterectomy, and varicose vein removal operations. Dr. Nagy’s patient care philosophy is based on the belief that every patient has the right to be heard and listened to. He makes a conscious effort to understand the patients experience to correctly diagnose and communicate with the patient to ensure they can make the most informed decisions for themselves. Personally, Dr. Nagy enjoys cooking and having campfires with his kids in the backyard (including eating s’mores), swimming and traveling with his family. When he does have a day off, he likes waking up early, making a nice cup of coffee and sitting outside when it’s still cool and reading a book or the newspaper.
