Overview
I am an immunologist who treats primary immunodeficiencies in children and adults. I see patients with recurrent infections and fevers, drug allergies, hereditary angioedema, and secondary immunodeficiencies. Our program offers cutting-edge clinical trials to provide the best treatment options for patients with immunodeficiencies. When I first meet patients, I try to put them at ease. Coming to a doctor's office can cause a lot of anxiety, especially for children. I try to identify key issues, as well as strategies to help with those problems. My goal is to improve the quality of life for children and adults so they can lead a normal life. Outside of work, I enjoy martial arts, gardening, cooking, and spending time with my wife and three children.

Duke Infusion Center South Durham
I first became interested in pursuing a career in medicine after being a camp counselor for children with autoimmune type I diabetes when I was in college. I wanted to learn more about and care for patients who had autoimmune diseases and immune dysregulation, which is what led to my dual training in both rheumatology and allergy immunology. My clinical practice, where I teach medical students, residents and rheumatology and allergy/immunology fellows, reflects this comprehensive immunologic approach. Diseases in which I have particular expertise include rheumatoid arthritis, Sjogren's syndrome, autoimmune inflammatory eye disease and common variable immune deficiency (CVID). I have several family members who also have autoimmune diseases and I have learned that care can be long term and involve a team approach. As a result, patient-centered care has become a personal goal. Dr. Tarrant is rated as an Advanced provider by MediFind in the treatment of Primary Immunodeficiency (PID). Her top areas of expertise are Common Variable Immune Deficiency, Primary Immunodeficiency (PID), Severe Combined Immunodeficiency (SCID), and Arthritis.
