I am the chief of pediatric heart surgery at Duke Health. Being a heart surgeon was always a dream of mine as a child. Spending a summer in medical school with legendary pediatric heart surgeon, Aldo Castaneda, cemented my desire to devote my life to this profession. Clinically, I love the creativity, complexity and challenge associated with my work. I am also able to satisfy my investigational curiosities through an active basic and clinical research laboratory focusing on congenital heart disease. I consider myself extremely lucky to be able to fulfill this dream back at Duke, a place that was so influential in my surgical training. Outside the hospital, I most enjoy spending time with my wife of 20+ years and three young children. We are an active family, always on the go… which mirrors my life at work.
