My Locations
About Me
I am a stroke-trained neurologist and neurohospitalist. I mainly manage acute neurological conditions in the hospital setting, and help direct Duke Regional Hospital's stellar acute stroke program, where we are recognized by the Joint Commission as a Primary Stroke Center. I am very interested in how we, as health care providers, deliver neurologic care in the hospital, and how we can improve that care and resulting health outcomes. I also see patients in clinic with cerebrovascular diseases, stroke, and aneurysms and manage these diseases long-term. When I am away from the hospital I enjoy spending time with my wife and our young daughter, and participate in auto racing and high performance driving events.

Ratings and Reviews
The ratings and reviews are based on patient responses to the overall provider rating question from the survey. The question reads: “Using any number from 0 to 10, where 0 is the worst provider possible and 10 is the best provider possible, what number would you use to rate this provider?” Responses are converted to a 5-point rating system and applied consistently to all providers. Learn more about our survey process. Patients who see some types of providers receive a different version of the patient satisfaction survey. Those results are not available on DukeHealth.org.
