Valley Orthopedic

Residents working in Cadaver Lab with Trauma Attending, Adam Warren MD, MPH

The Valley Orthopedic Surgery Residency (VOSR) in Modesto, northern California’s only AOA accredited orthopedic residency, opened July 2013 with four residents. Training focuses on creating the next generation of great orthopedic surgeons, relying on the volume and diversity of orthopedic pathology here coupled with hands on learning and early operative experience.

A strong didactic component of the program is daily protected education time that covers all aspects of orthopedics from basic sciences to clinical practice and evidence based medicine. Anatomy courses utilize fresh frozen cadavers for dissection and technical learning to supplement lectures. Our academic emphasis is exemplified by two residents scoring the 95th and 98th percentile nationally on this year’s OITE. We stress research, our residents have nine posters accepted to this year’s AOAO meeting in California. 

Our hospital is a busy Level II trauma center accredited by the A.C.S. Our ER has about 100,000 visits per year. Additionally, the residents have their own “teaching” patients and surgeries generated through the Health Services Agency system. These clinics and cases are staffed by an attending but are the primary responsibility of the residents. Our Program Director, Marc Trzeciak, DO, relies on his experience in clinical practice, and years as a residency and fellowship faculty, to create a strong learning environment. He is joined by a diverse and ever growing faculty of orthopedic surgeons, representing various subspecialties.

The program is a collaboration between the Valley Consortium for Medical Education, Doctors Medical Center, Stanislaus County Health Services Agency, Stanislaus Orthopaedics and Sports Medicine Clinic and the Midwestern University OPTI.  Learn more at
