Biography

Michael Klassen was born in Bakersfield, California, attended Bakersfield High School and Bakersfield College, and graduated from the University of Southern California School of Business in 1974 with a degree in business management and finance.

In 1973, during his college career, he started a business with a colleague in real estate development named Carver-Klassen Properties. In 1974 he earned a General Contractors license and continued to develop commercial real estate properties until 1986. During that time, in 1977, he also co-founded Pine Ridge Winery in Napa Valley. The winery flourished and in 1985 Michael sold his interest in the winery to attend medical school.

In 1985 Michael entered the UCLA School of Medicine where he received his medical doctorate degree in 1989. He then completed a surgical internship year at the University of California, San Francisco, with an additional year of general surgery residency training before completing four years of orthopaedic surgery training.

Dr. Klassen has completed research on topics including rapidly exchangeable calcium coupling in myocardial cells, the roll of tumor necrosis factor in septic shock, the effect of total gastrectomy in advanced gastric cancers, strength properties of autoclaved cortical bone, total joint replacement in patients with juvenile rheumatoid arthritis, osteonecrosis of the femoral head, knee arthrometry and MRI and arthroscopic findings in patients with anterior cruciate tears, treatment of humeral nonunions, olecranon fractures and other related orthopaedic topics. He has numerous presentations and publications including the American Journal of Physiology, American Journal of Surgery, American Surgeon, and International Journal of Pancreatology.

Dr. Klassen is the President of Monterey Peninsula Orthopaedic & Sports Medicine Institute and practices orthopaedic surgery with emphasis in arthroscopic surgery and sports medicine in Monterey, California. Dr. Klassen is a Board certified Diplomat of the American Board of Orthopaedic Surgery and a Fellow of the American Academy of Orthopaedic Surgery. He is a member of the Arthroscopy Association of North America, American Academy of Sports Physicians, Association of the Professional Team Physicians, Western Orthopaedic Association, California Orthopedic Association, California Medical Association and the Inman Abbott Society of San Francisco and a Qualified Medical Evaluator. Dr. Klassen is Medical Athletic Director & Team Physician for California State University at Monterey Bay Otters and Monterey Peninsula College Lobos.

Dr. Klassen is a member of the Board of Directors of the California Orthopaedic Association and has been selected as a reviewer for the Journal of Bone and Joint Surgery.
