About David Shearer, MD

Dr. Shearer completed his undergraduate degree in mechanical engineering at the Massachusetts Institute of Technology, and subsequently attended the University of Washington in Seattle for his medical school degree. Before beginning his residency training, he obtained a Masters Degree in Public Health at the Harvard School of Public Health focusing on clinical outcomes research and global health. He completed residency training at UCSF followed by subspecialty training in orthopaedic trauma surgery at Harborview Medical Center in Seattle and foot and ankle surgery with Dr. Mike Coughlin in Boise, Idaho. His clinical interests include the treatment of complex musculoskeletal injuries and both acute and post-traumatic conditions involving the foot and ankle. His primary research interest involves working with the Institute for Global Orthopedics and Traumatology at UCSF to improve educational and research programs in developing countries through academic partnership.
