About Me

Dr. Roger Sohn specializes in problems of the shoulder, elbow, and hand. He is double fellowship-trained and board certified by the American Board of Orthopaedic Surgeons. After graduating with honors from Loma Linda University School of Medicine, he completed orthopedic surgery residency at Harbor-UCLA Medical center. During his first fellowship at UC Davis Medical Center, he focused on upper extremity disorders including the hand, elbow, and shoulder. His second fellowship at Lake Tahoe Orthopaedic Institute gave him advanced training in minimally invasive surgeries such as shoulder and wrist arthroscopy. He has extensive experience with simple and complicated problems of the upper extremity.

Dr. Sohn strives to educate his patients about their problems as well as the various non-surgical and surgical options. His goal is to treat his patients in a way that minimizes the impact of their condition on their lives.

While some people eventually need surgery, many are pleasantly surprised to find that a new type of exercise regimen or splint can cure the problem. Of course, for those who need surgery, I find it very satisfying when I am able to make such a tangible difference in their mobility, stability, and quality of life through doing the best surgery possible.
