Certified Nurse Practitioners

Certified Nurse Practitioners, or Nurse Practitioners, work in collaboration with physicians and other healthcare professionals. They obtain medical histories and perform physical examinations. Nurse Practitioners are able to diagnose and treat acute and chronic health problems. They are also qualified to write prescriptions and order and interpret tests and procedures. You may see one of our Nurse Practitioners at your next office visit or at the hospital.
