The practice, which employs 86 people company-wide, has offices in Lafayette and Estes Park in addition to the Longmont headquarters.
The Frederick office, at 4943 Highway 52, will be open for clinical appointments and X-rays on Tuesdays and Thursdays. Dr. Gerald Rupp will see patients there, along with a nurse practitioner, though Front Range Orthopedics & Spine marketing manager Adrienne Bulinski said the number of providers could grow by fall or winter.
The new office has five exam rooms and digital X-ray equipment onsite, while the company has surgery and physical therapy centers, as well as magnetic resonance imaging in Longmont.
The 36,000-square-foot Indian Peaks Medical Center, owned by Longmont United Hospital, opened last fall with primary-care, cardiology and diagnostic departments.
