Physician Extenders

Our patient care team includes an outstanding group of experienced physician assistants and nurse practitioners to meet your orthopedic care needs.

Certified Physician Assistants (PA-Cs) and Nurse Practitioners (APRNs)

Before your visit with a physician, one of our certified physician assistants may perform your initial examination. Our PAs and APRNs are specially trained in orthopedic injuries, and they work alongside our board-certified physicians to:

  • Document your medical history
  • Perform physical examinations
  • Prescribe medications
  • Order laboratory tests
  • Provide treatment

Our physician assistants and nurse practitioners are accredited by their respective national certifying organizations and licensed by their respective state boards in Kansas and Missouri. Meet the team:
