About Me

I am a general rheumatologist fluent in both English and Spanish, with a strong commitment to providing compassionate, comprehensive care. I believe in treating the whole person, not just their disease, and I strive to understand each patient’s unique background, values, and needs. By combining medical expertise with a holistic approach, I aim to build meaningful relationships and empower patients to actively participate in their care. I am passionate about improving quality of life and fostering trust through open, culturally sensitive communication.

Insurance

Duke Health contracts with most major health insurance carriers and transplant networks, including the ones listed below. 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.
