Philosophy of Care 

Dr Rappaport's training and experience has prepared him in a round about way for his current roles. He completed his undergraduate degree in economics at the University of Pennsylvania and the London School of Economics. He then received a Masters in Education from the University of Pennsylvania, and began to teach in an alternative high school that was a joint effort of the University of Pennsylvania and the Philadelphia Public Schools. He taught for four years, and for the final two years was Head Teacher (Principal) at the school. He subsequently went back to school to take science courses and attended Yale Medical School. He completed a residency and a fellowship in Developmental and Behavioral Pediatrics at Children’s Hospital, Boston. He has worked to establish the new Division of Developmental Medicine and the Developmental Medicine Center over his 35 year long career at Boston Children's Hospital.
Dr. Rappaport is committed to the highest quality of care guided by the most recent research available to guide his medical opinions. He is committed to family centered care and involving families in the complex decisions surrounding the care of children with neurodevelopmental issues.
