Philosophy of Care 

Dr. James Kasser was born in Pittsburgh, Pennsylvania; the second of four children, and the son of an engineer.  Following completion of high school in Oakmont, Pennsylvania, he completed a degree in mechanical engineering at Lehigh University.  Rather than return to Pittsburgh to pursue an engineering career in the metals industry, Dr. Kasser switched to bioengineering and then to medicine, moving to Boston in 1972 and attending Tufts University School of Medicine.  It was at Tufts that Dr. Kasser was exposed to Dr. Henry Banks and a number of outstanding orthopaedic surgery mentors that set him on a career in academic orthopaedic surgery.  After completing his residency, he did a fellowship at DuPont Institute in Wilmington, Delaware.  Rather than being enthralled with the rapidly developing innovations in total joint reconstruction and arthroscopy, he was motivated by caring for young children with congenital deformities, growth abnormalities and leg length differences.
