Overview
My specialty is heart failure, especially advanced heart failure. We’re one of the largest heart transplant and mechanical support device programs in the world. We have vast experience, both in terms of medicine and surgery and all the things that go along with it. We have a level of expertise across the board, so you’re not just going to get pigeon-holed into one treatment that we happen to be good at. We have the ability to identify what treatment or treatments are best for you, then target each individual therapy for each individual patient. Many of the patients who come to see us have already seen other cardiologists, and many have been told there’s nothing more anybody can do. We try to take a fresh look at each person and we almost always find that there’s something we can do to help – maybe something simple like adjusting medications, or maybe a new device or adjustment of an existing device, or something more dramatic like a heart transplant or mechanical heart device.

Duke Cardiology Clinic - Clinic 2F/2G
I am a cardiologist who specializes in advanced heart failure and heart transplant. I always strive to take a fresh look at patients and see what treatments we can offer that they may have not had before. I spend about half of my time doing clinical research that focuses on the outcomes of patients with heart failure and other cardiovascular diseases. We look for opportunities to improve care and new ways to treat heart disease. Our patients are the center of our universe and we look for the best ways possible to treat them. One of my favorite parts of my job is taking care of patients who think the road has ended and being able to offer them several new roads to improve their lives.
