Allergy & Asthma Care

What Allergy & Asthma Care does

Allergy & Asthma Care, Ltd. is a privately-held specialty medical practice founded in 1984 by Dr. Barry Zeffren, a Board Certified internist specializing in Allergy and Immunology. The practice provides allergy and asthma diagnosis and treatment to children and adults across Metro East Illinois from five office locations in Glen Carbon, Alton, Litchfield, Greenville, and Breese. Core services include skin and blood allergy testing, pulmonary function testing, environmental control planning, medication management, and immunotherapy (allergy shots) administered over a 4-5 year desensitization cycle, which the practice reports is over 90% effective in reducing patient symptoms. Specialized lines include bee sting testing and chronic cough treatment, and a free downloadable allergy-free recipe eBook is offered as a patient engagement tool.

The underlying technology is conventional clinical medicine rather than a software platform: standard diagnostic testing equipment, allergen extract-based immunotherapy protocols, and in-person consultations. The practice is supported by a content marketing infrastructure including a blog with 14+ articles spanning 2013-2025, educational videos, checklists, and a newsletter, used primarily for patient acquisition and education rather than service delivery. Patient intake occurs via phone, online appointment form, or in-person visits.

The business model is fee-for-service medical practice revenue, billed through patient insurance (all insurances accepted), with no disclosed direct-pay or subscription pricing. The practice is entirely founder-owned with no external investment, no parent company, and no disclosed M&A activity. Customer segments are individual patients segmented geographically across Metro East Illinois and by condition (allergic rhinitis, asthma, hives, food/drug/bee sting allergies, immunodeficiency, chronic cough). Headcount of 11-50 employees supports a single-principal-physician specialty clinic structure, with the founder as the named clinical anchor.

Broad incumbents

• AllerVie Health: A national allergy, asthma, and immunology specialty platform operating dozens of clinics across the U.S. It is the most direct scaled analog for a multi-location allergy practice and a likely acquirer category for a regional operator like Allergy & Asthma Care.

Others

• Asthma and Allergy Foundation of America (AAFA): The leading U.S. patient advocacy and education organization for asthma and allergies. Not a competitor, but comparable in patient-education emphasis and an important referral source for allergy practices.
• American College of Allergy, Asthma & Immunology (ACAAI): Professional society for board-certified allergists/immunologists. Relevant context for clinical standards, continuing education, and the credentialing framework that supports the practice's physician moat.

Direct peers

• Family Allergy & Asthma: A multi-location allergy and asthma specialty practice providing testing, immunotherapy, and pulmonary care. Closely comparable service mix and treatment offerings, with a similarly physician-led multi-office model.
• National Allergy & ENT: A specialty practice combining allergy/immunology with ENT services across multiple locations. Comparable in clinical scope and in its mix of testing, immunotherapy, and chronic respiratory care.
• Aspire Allergy & Sinus: A growing multi-state allergy and sinus specialty clinic offering immunotherapy, allergy testing, and chronic condition management. Comparable services, patient demographics, and treatment protocols, but at significantly larger scale and with a stronger digital/telehealth layer.
• Premier Allergy & Asthma: A multi-site allergy, asthma, and immunology practice with board-certified specialists offering testing, immunotherapy, and chronic cough treatment — overlapping services and patient profiles with the subject company.

Regional players

• Allergy & Asthma Specialists: A regional specialty practice offering allergy and asthma care comparable to Allergy & Asthma Care Ltd. Similar size, structure, and patient mix; relevant as a benchmark for a regional single-/few-office competitor.
