Board-certified in allergy and immunology, San Diego physician Michael H. Mellon practices at the Kaiser Permanente Zion Medical Center campus and the Kaiser Permanente Vandever Medical Offices in Allied Gardens, both within the 92120 ZIP. He earned his medical degree from the Lewis Katz School of Medicine at Temple University and has contributed to published research on pediatric asthma control, IgE receptor characterization, and allergen immunotherapy outcomes. His clinical practice covers the full spectrum of allergic and immunologic conditions, including seasonal and perennial allergic rhinitis, food and insect venom allergies, chronic urticaria, eczema management, and drug hypersensitivity evaluation. Patients with complex medication allergies or those requiring allergen-specific immunotherapy fill compounded prescriptions at Alvarado Compounding & Retail Pharmacy, which formulates custom dosing for sublingual and injectable protocols. Dr. Mellon's work alongside department colleagues on asthma quality-of-care measurement and the TRACK instrument for pediatric asthma control has informed national clinical guidelines. The Allied Gardens location on Waring Road near the Zion campus provides coverage for families across San Diego's eastern corridor, from SDSU-adjacent neighborhoods through the residential streets south of the 8 freeway.
