I provide the best medical care possible because I treat every patient as if he or she is a member of my own treasured family.

Specializing In

I undertake adult cardiac surgery (coronary artery bypass grafting, valve repair/replacement, transcatheter aortic valve replacement, aortic aneurysm repair, aortic dissection, etc.), assist devices, extracorporeal membrane oxygenation, and transplant.
