Philosophy of Care 

"I was born in Pittsburgh, PA, the second of four children and the son of an engineer. Following completion of high school, I earned a degree in mechanical engineering at Lehigh University. Rather than return to Pittsburgh to pursue an engineering career in the metals industry, I switched to bioengineering and then to medicine, moving to Boston in 1972 and attending Tufts University School of Medicine. It was at Tufts that I was exposed to Dr. Henry Banks and a number of outstanding orthopedic surgery mentors who set me on a career in academic orthopedic surgery.

After completing my residency, I did a fellowship at DuPont Institute in Wilmington, DE. Rather than being enthralled with the rapidly developing innovations in total joint reconstruction and arthroscopy, I was motivated by caring for young children with congenital deformities, growth abnormalities and leg length differences."
