Morna J. Dorsey


Medical Director, Pediatric Immunology and Allergy Center, San Francisco
Pediatric immunologist and allergist

Dr. Morna Dorsey serves as director of the Pediatric Allergy and Immunology Center. A pediatric immunologist and allergist, she specializes in caring for patients with inborn errors of immunity (various immune disorders resulting from genetic mutations). She also serves as co-director of UCSF's newborn screening program for severe combined immunodeficiency (SCID) and directs the pediatric allergy and immunology fellowship program, which trains doctors in this subspecialty.

Dorsey's expertise in rare immune system conditions enables her to provide special insight into common immune conditions, such as food allergies, and she co-leads a multidisciplinary clinic devoted to eosinophilic gastrointestinal disease. Her professional and research interests include discovering new treatments for both common and rare immune disorders and delivering collaborative, individualized care for every patient.

Dorsey earned her undergraduate degree from the College of William & Mary. At the University of South Florida, she earned her medical degree and completed a residency in pediatrics. She completed a fellowship in allergy and immunology at Boston Children's Hospital, the pediatric teaching hospital of Harvard Medical School, where she also completed a master of medical science degree in clinical investigations. She has chaired several committees in national allergy and immunology organizations including the American Academy of Allergy, Asthma and Immunology and Clinical Immunology Society.

Outside of work, Dorsey enjoys traveling, spending time outdoors with her husband and young son, and hiking with their family's rescue dog.
