The Advanced Practice Providers (APP's) are board certified nurse practitioners and physician assistants who practice in collaboration with neurosurgeons and neurointensivists, providing a team approach in the management of patients' health care.  APP’s are licensed medical professionals who can examine, test, treat and prescribe medications for patients. Our APP’s practice both in the hospital and in our clinics.  

The goal of advanced practice providers is to ensure continuity of care and increase access to neurosurgical treatment. They also provide patient and family education regarding diagnoses and treatment plans. They work closely with your doctor to deliver high quality care.
