Orange County’s Leading Neuroscience Program

The physicians of Newport Neurospecialists and Newport Neurohospitalists have come together to bring patients the most comprehensive neurosciences program in Orange County. Newport Neurospecialists offers significant expertise in many neurological programs.

Our mission – an integrated, multidisciplinary team approach to disorders of the brain, nerves and spine using the best evidence based clinical care, state of the art technology, and advanced clinical research, all focused on the individual patient need.

With the mission of delivering the best health care to our community, Hoag established one of the first neurohospitalist (hospital-based neurologists) programs in the nation.

With the number of stroke patients reported each year, it’s critical to aggressively and expediently treat neurologic illness with an in-hospital team.

When experiencing a stroke or other neurological emergency, you will most likely be transported to the closest hospital, not to the nearest neurologist office. So why not house these experts right at the hospital?

Hoag believes it’s essential to have neurologists and neurosurgeons available at the hospital, especially during emergencies such as stroke. Our commitment is not only to pioneer this progressive concept, but also to continually expand our vision and work toward delivering the finest neurological care to the patients we serve.
