Our Physician Assistants (PAs) work closely with our surgeons to coordinate and expedite your care. All have endured a rigorous preclinical training program and obtained certification through a qualifying exam, demonstrating skill and knowledge at a high standard. Except for performing surgery, our PAs are capable of providing the full gamut of musculoskeletal health care services including:

  • Physical Examination, Diagnosis and Treatment of Illness/Injury
  • Ordering and Interpreting Tests
  • Performing Minor Office Procedures (Splint/Cast Application, Injection)
  • Assisting in Surgery
  • Issuing Prescriptions and Other Pertinent Paperwork

Each PA has trained rigorously with each of her supervising physicians to ensure consistency while maintaining individualized care to each patient.
