Allergy & Asthma of the South Shore PC was founded in 2012 by Alissa Hersh MD. Dr. Hersh is board certified in pediatrics and allergy and immunology. This practice was formed to benefit patients from the South Shore of Long Island and the surrounding areas by providing outstanding quality of care and treatment/management of allergic disease. Dr. Hersh has been recognized for her excellence in diagnosing, managing, and treating environmental allergies, food allergies, drug allergies, asthma, eczema, hives, contact dermatitis, eosinophilic esophagitis, and immunodeficiency. Allergy testing, food and drug challenges, patch testing, and immunodeficiency evaluations are all routinely performed on an as needed basis. If allergy testing is required than we request that all antihistamines be withheld for 5 days prior to initial visit. Please arrive 10 min prior to initial visit.
