Philosophy of Care

It was the dedication, skill, and compassion of the early pioneers of heart surgery that allowed my own father to receive a life-saving heart operation before I entered medical school. The inspiration I felt then to devote myself fully to developing the skills and knowledge necessary to pay that benefit forward has only grown stronger with each patient I now have the privilege of caring for today.


I completed my general surgery training at the Massachusetts General Hospital, during which I spent three years performing research in mitral valve disease and surgical therapies for heart failure at the Brigham and Women’s Hospital. I then completed my adult cardiothoracic surgery training at Massachusetts General Hospital, followed by congenital cardiac surgery training at both Boston Children’s Hospital and Seattle Children’s Hospital. For additional specialty training in both neonatal and adult congenital cardiac surgery, I spent an additional year as a cardiac surgery instructor at Columbia University/Children’s Hospital of New York. I joined the cardiac surgery faculty at Boston Children’s Hospital in July 2020 and am actively involved in all aspects of neonatal, pediatric, and adult congenital cardiac surgery, with a focus on developing improved techniques and systems for the care of patients with adult congenital cardiac disease.
