Philosophy of Care 

It is an honor and privilege to be part of the Spinal Program in the Department of Orthopedic Surgery at Boston Children’s Hospital. We are fortunate to have a breadth and depth of experience that allows us to care for the most complex and challenging pediatric deformities. Our goal is to continue the tradition of individual, patient-centered care for our spinal deformity patients, whether they are local or international, straightforward or complex, operative or non-operative.
