Summary

I am a board certified vascular and endovascular surgeon. My clinical focus is treating: carotid disease to prevent stroke, thoracic and abdominal aortic aneurysm to prevent rupture as well as peripheral arterial disease for claudication and limb salvage. I offer both the traditional open and the minimally invasive approaches requiring no incision based on what is better for each patient. I am passionate about clinical research in vascular surgery leading over 20 clinical trials at Hopkins.
