Advanced Practitioners
Our clinical team includes physician assistants (PAs), nurse practitioners (NPs) and registered nurses (RNs) who specialize in orthopaedics and play a key role in providing quality, coordinated patient care.
PAs and NPs are clinical professionals with advanced degrees who are licensed to practice medical care. They work together with physicians and can evaluate and treat many orthopaedic conditions. Our RNs provide support during patient visits and play important role in patient education, guiding you through treatment and rehabilitation.
