Xiao Chloe Wan, MD, with Allergy and Asthma Associates of Northern California

Dr. Xiao Chloe Wan became an allergist because she was drawn to the complexity of allergic diseases and the direct impact that environment and genetics have on our health. She feels passionately about applying our ever-growing knowledge about allergy and immunology to help improve the quality of life of her patients. She also takes pride in practicing in a field that affects people of all ages.

In her medical training, she was awarded a grant to study exercise-induced asthma and trained under nationally recognized physicians in drug allergy and immunodeficiency. She also collaborated with one of the world's leading experts in asthma research to publish an article on current therapeutic targets for asthma management.

Dr. Wan is originally an East Coast transplant who has never left California after being drawn to its vibrant outdoor culture and beautiful landscapes. In her spare time when she is not chasing her toddler around, she enjoys outdoor hiking and traveling with her husband. She is also fluent in Mandarin and Japanese.
