Board-certified allergist-immunologist Bernard A. Feigenbaum, M.D., FAAAAI in Encinitas treats adult and pediatric allergy, asthma, and immunologic conditions at San Diego Allergy, Asthma & Immunology Consultants on North El Camino Real. The practice's same-day skin-prick and intradermal testing protocols cover environmental, food, drug, and insect-venom allergens including penicillin allergy evaluation, a diagnostic depth that integrates with the immune-focused care at ActiveMed Integrative Health Center. Certification through the American Board of Allergy & Immunology followed an MD from Boston University School of Medicine (1989), internal medicine residency and chief residency at Scripps Mercy Hospital, and allergy/immunology fellowship at Scripps Clinic in La Jolla. Published research spanning 17 articles on aspirin-exacerbated respiratory disease, chemotherapy desensitization, and chronic rhinosinusitis includes peer-reviewed contributions to the Journal of Allergy and Clinical Immunology, reinforcing a clinical-research interface that parallels the investigational dermatology work at CA Dermatology & Clinical Research Institute. Highest-acuity services include multi-step rapid drug desensitization protocols for chemotherapy agents and monoclonal antibodies in oncology patients with confirmed IgE-mediated hypersensitivity.
