Allergist and immunologist Dr. Warren Pleskow in Encinitas is double board-certified in internal medicine and allergy-immunology, with over 40 years treating the North San Diego coastal community from his El Camino Real practice. His Scripps Clinic La Jolla fellowship in allergy and immunology followed internal medicine residency and internship at the State University of New York at Buffalo, producing a clinical research career that includes principal investigator roles in over 300 clinical trials and authorship of more than 30 medical papers, a diagnostic precision that extends to the allergic conjunctivitis evaluations coordinated with Acuity Eye Group. The practice operates North County's largest travel immunization clinic, administering destination-specific vaccination protocols for international travelers alongside its core allergy, asthma, and immunology services. Allergy skin testing, spirometry-based pulmonary function assessment, and subcutaneous immunotherapy injection programs address conditions from allergic rhinitis and eczema to stinging-insect anaphylaxis, a multi-pathway approach to immune modulation that complements the integrative allergy support offered at Chong Acupuncture & Integrative Medicine. Active clinical research enrollment in asthma, allergy, and COPD trials provides qualifying patients access to investigational biologic and small-molecule therapies before commercial availability.
