Allergist and immunologist Ronald Simon, MD, in Encinitas practices through Scripps Clinic on Santa Fe Drive, where he serves as Emeritus Head of the Division of Allergy, Asthma and Immunology. Board-certified in Allergy and Immunology since 1979 with over 160 peer-reviewed publications, his clinical research on aspirin-exacerbated respiratory disease and food-additive hypersensitivity informs the integrative allergy management protocols also employed at Stengler Center for Integrative Medicine. Subspecialty focus areas include AERD desensitization, drug allergy evaluation, food allergy challenge testing, and the role of supraesophageal reflux disease in chronic rhinosinusitis and asthma. His position as Adjunct Professor at the Scripps Research Institute and former co-chairman of the FDA committee on adverse reactions to food constituents connects clinical care with the pediatric allergy referral network that includes Children's Primary Care Medical Group. Highest-complexity evaluations involve multi-drug desensitization protocols for patients with confirmed aspirin or NSAID hypersensitivity requiring cardiovascular prophylaxis or anti-inflammatory therapy.
