Burbank Orthopedic Surgeons and Musculoskeletal Specialists

The story of OSS (also known as Orthopedic Surgery Specialists) begins more than 70 years ago! The medical practice was started in 1947 by two very well-trained orthopaedic surgeons, Dr. Donald Spiers and Dr. Lewis Kistler. To keep up with the influx of people moving to Los Angeles and the dynamic advancements in orthopaedic procedures, these doctors expanded their network, inviting Dr. Howard Hambrecht, Dr. Christopher Jessen, and Dr. Russell Vergess to join.  

OSS is now a diverse group of health care providers focused on musculoskeletal care.  OSS is committed to giving you an excellent musculoskeletal health outcome, and an excellent patient experience.
