What do we do? We evaluate and treat patients with various allergic, rheumatologic and immunologic disorders of childhood including pediatric asthma, food allergy, atopic dermatitis (eczema), hives, allergies, hay fever, anaphylaxis, stinging insect allergy, immunodeficiency, recurrent infection, chronic cough, vocal cord dysfunction, exercise-induced asthma, and illnesses which may complicate chronic allergic disease such as gastroesophageal reflux. 

Why National Jewish Health? The division conducts cutting edge clinical and translational research into the mechanisms underlying asthma, food allergy, atopic dermatitis (eczema), autoimmune disease and immunodeficiency and is involved in novel treatments for patients who have difficulty managing allergic and immunologic disorders.
