About me

Dr. Working is the Director of Orthopaedic Trauma & specializes in treating broken bones at the Marquam Hill campus. His clinical interest is in the care and needs of traumatically injured adults and children of all ages. He treats patients with fractures of the pelvis, arm, elbow, shoulder, ankle, foot, leg and knee. He is particularly interested in the prevention and care of musculoskeletal infections resulting from trauma, and in the underlying science behind fracture healing. He is an active researcher in fracture care with over 30 publications to date. He is an active member in the Orthopaedic Trauma Association, in AO Trauma, and the Orthopaedic Research Society. 

Dr. Working was awarded the title of the John and Susan Hayhurst Distinguished Scholar in Orthopaedic Research and Innovation by the OHSU School of Medicine. During the three-year appointment he will use this generous support to develop and strengthen a growing core of clinical and engineering musculoskeletal researchers with common interests in musculoskeletal trauma.

Dr. Working and his wife are both natives of the Pacific Northwest and are pleased to have returned home. Dr. Working earned his medical degree at the Pittsburgh School of Medicine. He completed an orthopaedic residency at the University of Utah where he began to focus his interest on the traumatically injured patient. He completed an orthopedic trauma fellowship at the Orthopaedic Trauma Institute at the University of California at San Francisco. His research focuses on optimizing clinical orthopaedic trauma care, musculoskeletal infections and their treatment, and problem fractures (nonunion).
