Physician Assistants:

During your treatment course, you may have the opportunity to be seen and evaluated by our Physician Assistants. On the occasion when our physicians are in surgery, there is a Physician Assistant available in the office for a clinical consultation.  Physician Assistants are licensed medical practitioners, who under the direct supervision of our team of physicians, can perform initial and follow-up assessments, order radiographs (x-ray, MRI), and prescribe medications when indicated. They can also prescribe physical therapy and apply a cast and/or brace subsequent to a recent injury. Their focus is to provide the highest quality of care while emulating our supervising physician’s protocols during your evaluation. Our goal is to have our Physician Assistants closely work and communicate with our supervising physicians to provide you, the patient, the most immediate and highest quality of care.
