It has the ability to scan children and adults. A private dressing room is available and our qualified, compassionate technologist is always present during your scan. Appointments and results for your MRI are usually available within two days. Our goal is to offer MRI services better, faster and less expensive than other MRI facilities in our area. We make patient care, comfort and convenience a top priority.

    Yearly, Orthopedic Associates physicians participate in community athletic programs by volunteering their time to perform athletic sports physicals at both Chico High School and Pleasant Valley High School. OANC physicians also volunteer their time to be the "physician on duty" at both Chico High and Pleasant Valley High football games. Currently, Dr. Komas is the team orthopedic surgeon physician for all of Butte College athletics.
