During this time, he served as an oral examiner for the American Board of Orthopedic Surgery, holding that position for more than twenty years.
While on vacation in McCall, looking at possible retirement destinations, he thought McCall could use an orthopedic surgeon, considering the ample year-round recreation opportunities nearby.

For the knee, Dr. Kopplin utilizes patient-specific kinematic alignment protocols with medial pivot design total knee arthroplasties to optimize knee stability and ligament balance. This patient-specific approach aims to custom fit each knee to each patient’s individual anatomy.

Dr. May has numerous peer-reviewed journal publications focusing on blood conservation in joint replacement surgery, joint replacement techniques and minimally invasive surgeries to improve patient function and expedite recovery, as well as advanced technologies in joint replacement.
