Nurse Practitioners

Nurse Practitioners are important members of the health care team.  Our Nurse Practitioners work under clinical protocols developed by our physicians for the purpose of caring for the practice's patients.  Our Nurse Practitioners provide both urgent and routine care depending on the situation while working closely with our physicians to ensure that our patients receive the best care possible.  For more information about Nurse Practitioners please visit the American Academy of Nurse Practitioners.
