I am a noninvasive cardiologist with clinical and research specialties in peripheral artery disease, structural heart disease, and hypertension. I’ve been at Duke for over 10 years and in that time I’ve been proud to be part of Duke’s commitment to world class, patient-centric, personalized care. We are in the midst of major breakthroughs and advances in cardiovascular care, many of which have evolved here at Duke. But translating these advances to personalized care takes a strong partnership between a doctor and patient and I look forward to forging that relationship with each of my patients.
