Each NSC CCA office has a clinical nurse and patient advocate or "navigator" who will be your first contact into the CCA system. The navigator will work closely with NSC CCA physicians and navigators from other offices to arrange an itinerary of scheduled tests and appointments in a timely and efficient manner. An important resource and main point of contact for patients, the navigator helps guide you through your appointments, tests and treatment. The navigator will also be responsible for relaying information to the referring physician and other specialists involved with your care.
