About Me

Medical Director, Pediatric Cardiac Imaging, Joe DiMaggio Children's Hospital

I am a board-certified pediatric cardiologist with training in advanced cardiac imaging/cardiac MRI, and the medical director of Pediatric Cardiac imaging at Joe DiMaggio Children's Hospital.

I perform cardiac MRIs and echocardiograms on pediatric patients with a variety of congenital and acquired heart diseases. I have also introduced newly developed cardiac MRI sequences only performed in a few pediatric hospitals across the country, including the stress-perfusion cardiac MRI, at Joe DiMaggio.

As an imaging cardiologist, I get to help identify anatomic problems in a child's heart. This information and the images I capture help us to guide the medical management and also provide a better understanding for surgeons planning a procedure.

At Memorial, we work as a team to support and care for children and their families. Our goal is always to try to resolve the health concerns of a child, in turn improving their quality of life and that of their family.
