"I am honored to enter into families lives at crucial time points. From a newborn with complex heart disease to a teenager's heart that curiously flutters, I understand that these are frightening times in people's lives. I love being able to explain and demystify complex problems and provide a roadmap for the future. Our field has made incredible progress over the past 50 years, yet I am humbled by how far we still have to go. Caring for children with heart disease involves a multi-disciplinary approach and I'm privileged to work with such expert and energetic faculty and staff at Seattle Children's Hospital."
