Allergy Asthma and Sinus Centers

What Allergy Asthma and Sinus Centers does

Allergy Asthma and Sinus Centers is an independent, physician-owned medical specialty practice delivering allergy, asthma, sinus, and immunology care across four clinic locations in the Chicago southwest suburbs: Joliet (Crest Hill), Aurora, Countryside, and Bolingbrook. The practice was established in 1995, expanded through a 2022 merger with Western Springs Asthma & Allergy, and currently operates with two board-certified allergists (Dr. Maaz Mohiuddin, Dr. Syed Rizvi) and two physician assistants (Adriana Flores Munoz, Brenda Kelley).

The clinical offering combines a comprehensive diagnostic menu (skin prick, patch, blood, FeNO, body plethysmography, spirometry, rhinolaryngoscopy, food and drug challenges) with a full immunotherapy portfolio spanning Traditional Subcutaneous Immunotherapy (3-5 years), Sublingual Immunotherapy, Rush Immunotherapy, Oral Immunotherapy for food allergies, and the practice's flagship Ultra Rush Intralymphatic Immunotherapy (ILIT), which delivers equivalent results in three monthly ultrasound-guided lymph node injections and is described as the only such offering in Illinois. Adjacent services include biologic injections (Xolair, Nucala, Fasenra, Tezspire, Dupixent), IVIG/SCIG immunoglobulin replacement for immunodeficiency, venom immunotherapy, and aspirin desensitization.

The revenue model is professional services billing across office visits, diagnostic procedures, and treatment courses, with direct-to-consumer patient acquisition through ZocDoc marketplace listings, local SEO, blog content, and active social channels on Instagram, TikTok, Facebook, and X. ILIT is priced at $3,000-$4,000 per treatment course, functioning as a premium-priced differentiator that draws patients from beyond the immediate Chicagoland core. The practice is bootstrapped with no external funding, no parent organization, and no public disclosures of revenue or operating metrics.

Products and services

• Ultra Rush Intralymphatic Immunotherapy (Ultra Rush ILIT) An expedited immunotherapy course delivering 3 inguinal lymph node injections spaced over a 3-month period, marketed as producing desensitization results equivalent to 3–5 years of conventional allergy shots. It is the only service of its kind offered in Illinois and is available in introductory ($3,000) and full ($4,000) packages at the practice.
• Traditional Immunotherapy (SCIT) Standard subcutaneous allergen immunotherapy consisting of weekly injections over roughly 8 months, followed by monthly maintenance shots, used to desensitize patients to environmental allergens.
• Sublingual Immunotherapy (SLIT) Sublingual allergen drops taken at home as an alternative to traditional allergy shots, with comparable efficacy for many patients who prefer to avoid injections.
• Rush Immunotherapy An accelerated cluster immunotherapy protocol in which multiple allergy injections are administered over a shortened schedule to bring patients to maintenance dose quickly, reducing the overall time to symptom relief.
• Oral Immunotherapy (OIT) for Food Allergies Structured oral desensitization to food allergens combined with medically supervised Food Challenge Testing to confirm and quantify IgE-mediated reactions and tolerance.
• Venom Immunotherapy Venom-specific immunotherapy for patients with systemic reactions to bee, wasp, hornet, yellow jacket, or ant stings, aimed at preventing life-threatening anaphylaxis on re-exposure.
