Division of Allergy, Asthma & Immunology

Our Division of Allergy, Asthma & Immunology is staffed by members who are each a leader in their field, excelling at providing expert diagnosis and treatment for patients with allergic and immunologic conditions. All of our specialists are certified by the American Board of Allergy and Immunology, with all having additional subspecialty training in pediatrics or internal medicine. We work with patients of all ages to directly address allergies and improve comfort in every way possible, using extensive testing options, lifestyle modifications, medications, challenges, and more. Our physicians also lead Scripps’ internationally recognized center for Aspirin-Exacerbated Respiratory Disease and Drug Hypersensitivity. From significant drug or food allergies to seasonal allergies, we take highly individualized approaches to patient care that leverage the latest scientific advances and therapeutics to improve their daily quality of life. We have a speciality focus in food allergy both at the clinical level (diagnosis, management and potential therapeutic trials) as well at the scientific level collaborating with researchers at the Scripps Research Institute and the La Jolla Institute of Immunology.

Our Allergy, Asthma and Immunology Division supports an ACGME-accredited fellowship in Allergy and Immunology. Our two-year training program is tailored to develop excellent clinician-scientists through a combination of translational research opportunities and comprehensive clinical training. Our staff also serve as instructors for internal medicine and pediatric residents.

All of our Division staff are engaged in ongoing research and have authored publications in peer-reviewed journals covering a broad range of allergy topics including: vaccine allergy, pregnancy during asthma, aspirin exacerbated respiratory disease, food allergy, drug allergy, allergic contact dermatitis and chronic sinusitis.

  • The Division is actively researching treating peanut allergy with intralymphatic peanut immunotherapy to resolve peanut allergy and optimizing management of AERD/ aspirin exacerbated respiratory disease.
