Black & Kletz Allergy

What Black & Kletz Allergy does

Black & Kletz Allergy (legal entity: Yuill Black, MD and Michael R. Kletz, MD, P.C.) is a private Allergy and Immunology professional corporation founded in 1970 and operating across three office locations in the Washington, D.C. metropolitan area — McLean VA (1420 Springhill Road, Suite 350), downtown Washington DC (2021 K Street NW, Suite 524), and Manassas VA (7818 Donegan Drive). The practice is staffed by two board-certified allergists, Michael R. Kletz, MD and Appaji Gondi, MD, supported by 51-100 total employees, and serves both adult and pediatric patients presenting with allergic rhinitis, asthma, sinusitis, food and drug allergies, eczema, hives, insect sting allergies, and related immunological disorders.

Core services are organized around diagnostic testing and treatment. Diagnostics encompass skin testing, blood testing, pulmonary function testing (PFTs), patch testing for contact dermatitis, penicillin skin testing, and oral challenges for foods and medications. Treatments include traditional subcutaneous immunotherapy ("allergy shots") for indoor, outdoor, and stinging-insect allergies — reported effective in 80-85% of treated patients — alongside biologic monoclonal-antibody injections (Xolair/omalizumab, Nucala/mepolizumab, Fasenra/benralizumab, Dupixent/dupilumab) administered in-office for eligible asthmatic, urticaria, eczema, and chronic-rhinosinusitis patients. The practice also provides patient self-management training for inhalers, peak flow meters, and epinephrine auto-injectors, and offers telemedicine consultations.

Revenue is generated per-visit from consultations, in-office diagnostic procedures, immunotherapy courses, and biologic administration, billed through accepted commercial insurance plans; the practice is structured as a single professional corporation rather than a multi-specialty platform, and no external investment, parent company, or affiliate ownership is recorded. Patient acquisition is driven by a combination of physician and patient referrals, an active educational blog, a patient testimonials/review engine, earned-media positioning (NBC Today Show, ABC WJLA, NBC WRC, Fox 5, Washington Post, Washington Times, plus ongoing pollen-count contributions to local TV stations), and referral channels including physician, family, and co-worker referrals — though the practice has no disclosed marketing technology stack, no API, no AI tooling, and no integrations.
