Washington University allergists and immunologists provide comprehensive evaluation and management of patients with allergies, asthma, chronic sinusitis, allergic rhinitis (hay fever), urticaria (hives) and drug sensitivity. The board-certified allergists and immunologists in this group also have broad experience in the diagnosis and management of rarer and more difficult-to-treat inherited and acquired immunodeficiency disorders that lead to recurrent skin and respiratory tract infections.

Our offices serve as a resource to physicians and patients for diagnosis and treatment of allergic and immunological disorders ranging from the ordinary to the most challenging.
