About Me
I am a clinician-scientist in ophthalmology, who specializes in caring for patients with glaucoma, and I am dedicated to improving treatments for glaucoma through research. I have a special focus on glaucoma-related to inflammation (uveitic glaucoma), and I work closely with the uveitis specialists at the Center for Ocular Immunology at the Duke Eye Center. My goal is to provide the best possible patient care with an understanding of my patients’ needs and concerns. I grew up in North Carolina and feel privileged to care for patients in North Carolina and the surrounding areas. Outside of work, I enjoy the beach, watching sports, and spending time with family and friends.

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.

Before scheduling your appointment, we strongly recommend you contact your insurance company to verify that the Duke Health location or provider you plan to visit is included in your network. Your insurance company will also be able to inform you of any co-payments, co–insurances, or deductibles that will be your responsibility. If you proceed in scheduling an appointment and your health insurance benefits do not participate with Duke, your out of pocket liability may be higher. We will contact you regarding your coverage and patient liability. If you are uninsured, learn more about our financial assistance policy.
