The goal of the Neurology Residency Training Program at UC Davis is to prepare residents for the independent practice of clinical neurology. The program provides broad exposure to patient care across the age spectrum in a variety of in-patient and out-patient settings.

The UC Davis Department of Neurology is a national leader in providing clinical care and conducting research in neurological disorders, particularly in epilepsy, dementia, neuro-immunology, neuromuscular diseases, movement disorders, and stroke. Graduates of the residency training program are well-prepared to enter clinical practice or to continue training in a subspecialty or neuroscience fellowship.

To learn more about our post-graduate training programs, please see the Neurology Residency Training Program and Neurology Fellowships pages.  And please take some time to visit us on Facebook at our UC Davis Neurology Residency and Fellowship Programs page.
