About Me

My practice focuses on infants born with complete DiGeorge syndrome who have no T cells. T cells, which develop in the thymus, are the white blood cells that fight infection. Infants with complete DiGeorge syndrome are born without a thymus. Most children with this disease die by the age of 2. They need a thymus transplant to survive. I lead the only thymus transplant program in the United States. Families usually come to Duke and are treated as an inpatient or outpatient for four months. After that time, the family returns home, and the infant is followed locally with guidance from my team. Thymus transplantation is a research procedure. We have transplanted more than 70 infants with thymus tissue; more than 70 percent survive with good T cell function.

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.
