Physician, Banner - University Medicine Neurosurgery Clinic
I believe the best neurosurgery comes from working to continually improve every aspect of care: the patient experience, the technical perfection of each specific procedure, the technology we bring to bear, and the function of the multidisciplinary team that supports everything we do. I strive to lead in each of these areas.
