Clinical Staff

At Olympia Orthopaedic Associates, we take a team approach to evaluating and treating our patients’ injuries effectively. Our Physician Assistants and ARNPs are highly trained healthcare providers, who work closely with their orthopaedic surgeon to provide the highest level of care to our patients. They conduct exams; take medical histories; diagnose/treat muscle, bone or joint injuries and conditions, order and interpret tests, such as X-rays and MRIs; they order labs, EKGs and prescribe medications; and assist our doctors during surgery. They provide patients with education, guidance, therapeutic treatments, and are trained to recognize when patients need the attention of their surgeon or an additional specialist.
