Personal Statement

As a parent, I understand the stress involved with any doctor visit, particularly to a subspecialist. My goal is to provide you with all of the information needed to give you a thorough understanding of your child’s condition. I encourage questions and hope you will not leave our visit until you have asked every question that you have, no matter how big or small. I am fortunate to be surrounded by a wonderful team in the Division of Pediatric Cardiology to help care for children and their families, prenatally continuing through early adulthood. I firmly believe that you will find the care you receive here at Weill Cornell to be personalized, thorough, and compassionate.
