About

Bio

Dr. Purchase was born in Western Pennsylvania and remained there to attend college at Washington and Jefferson College. It was during this time, as a collegiate football player and biology major, that he became interested in orthopedic surgery as a career. He attended Temple University School of Medicine in Philadelphia, PA and stayed at Temple to complete his orthopedic residency. He supplemented his orthopedic residency with a sports medicine and shoulder surgery fellowship in San Francisco. After completing his fellowship, he practiced in a general orthopedic group with a focus on shoulder and sports medicine in California’s Central Valley. As a fully trained shoulder replacement surgeon, Dr. Purchase utilizes advanced arthroscopic techniques primarily and is equally comfortable with all open reconstructive techniques, from hemi-resurfacing procedures to revision shoulder replacements. Additionally, he puts an equal amount of time and effort into refining his general orthopedic skills. He routinely performs treatment of all manner of boney and soft tissue traumatic injuries, replacements of the knee and hip, knee arthroscopic procedures, and routine upper extremity work. Dr. Purchase’s philosophy of care is anchored in his belief that a well-informed patient is a better patient. His primary role is to serve as an advisor to his patients. This allows the patient to be an active participant in their care. Dr. Purchase is certified by the American Board of Orthopedic Surgery and is a fellow of the American Academy of Orthopedic Surgeons and Arthroscopy Association of North America.

Specialties
Doctors may have more than one area of specialty interest. Board certification in a specialty area means the doctor has completed formal training and has practice experience in that specialty, and has passed the certification examination from the corresponding accredited medical specialty board.
