About Me
I have more than 25 years of experience treating patients of all ages with spinal disorders. I have had an interest in the management of spinal disorders since starting my medical education. I performed residencies in both orthopaedic surgery and neurosurgery to gain a comprehensive understanding of the entire range of spinal disorders. My goal has been to find innovative ways to manage the range of spinal conditions, straightforward to complex. I have a focus on managing patients with complex spinal disorders. My patient evaluation and management philosophy is to provide engaged, compassionate care that focuses on providing the simplest and least aggressive treatment option for a particular condition. In many cases, non-operative treatment options exist to improve a patient’s symptoms. I have been actively engaged in clinical research to find the best ways to manage spinal disorders in order to achieve better results with fewer complications.

Areas of Expertise
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.

Clinical Focus and Research
My research spans a broad range of clinical research that evaluates the management of patients with spinal disorders. I have served as a principal investigator or site principal investigator for research evaluating spinal trauma, spinal cord injury, pediatric and adult spinal deformity, degenerative spinal disorders, spondylolisthesis, and spinal stenosis. The focus of all of these studies is to improve the selection of patients for optimal treatment, reduce complications related to treatment, and improve outcomes.
