Allergy, Asthma & Sinus Center

What Allergy, Asthma & Sinus Center does

The Allergy, Asthma & Sinus Center (legal entity: Allergy Associates, PA) is a private, physician-owned multi-state allergy, asthma, and immunology medical practice founded in 1980 and headquartered in Knoxville, Tennessee. The practice operates more than 35 clinical locations across Tennessee, Kentucky, Louisiana, and Georgia, staffed by 22 board-certified allergists. It provides comprehensive diagnostic services including skin-prick allergy testing, IgE blood testing, spirometry, and MiniCAT instant CT sinus imaging, alongside treatment services such as subcutaneous immunotherapy (allergy shots), sublingual immunotherapy (allergy drops), severe asthma biologic therapy, food allergy management, and Primary Immune Deficiency Disease care.

The business operates a tri-channel care delivery model: scheduled in-clinic visits at 35+ locations, walk-in care through the Allernow sub-brand at three Tennessee sites, and remote consultations via the Healow televisit platform. Revenue is generated through insurance-billed patient care services, including consultations, diagnostic procedures, immunotherapy administration (which carries 3-5 year patient retention), and ancillary services such as imaging. The practice also participates in sponsored clinical research trials (FLAIR, NIMBLE, VATHOS), adding a research revenue stream and patient access to investigational therapies.

The go-to-market motion combines physician referrals, self-referrals, and direct-to-consumer channels including online scheduling via Luma Health, a phone scheduling center (1-866-231-0701), and content marketing through provider blogs and the "Let's Clear the Air!" podcast. Technology integrations include Healow Patient Portal, Carequality HIE for interoperability, and Luma Health scheduling. The target customer base spans infant, pediatric, adolescent, and adult patients across the Southeast US, with no disclosed enterprise contracts or payer concentration. The practice is independently owned with no venture capital, private equity, or parent company involvement identified in the source materials.

Functional benefit

Brands

• Allernow: Walk-in allergy quick care clinic brand offering walk-in services for asthma, cough, sinus infections, and seasonal or perennial allergies at select Tennessee locations.

Products and services

• Allergy Skin Testing (Skin Prick Test) Quick, safe, and effective diagnostic method to identify allergy triggers. The allergist gently pricks or scratches the skin with small amounts of allergens such as pollen, pet dander, mold, or dust mites. Results appear within minutes as small red bumps.
• Immunotherapy (Allergy Shots) A series of injections that desensitize patients to specific allergens over time. Considered the closest thing to a cure for allergies, it involves a build-up phase (1-3 times weekly for 3-6 months) followed by a maintenance phase (every 1-4 weeks) lasting 3-5 years on average.
• Sublingual Immunotherapy (Allergy Drops) Needle-free alternative to allergy shots where custom-mixed allergen drops are placed under the tongue at home. FDA-approved tablets are also available for specific triggers like grass or ragweed.
• Asthma Treatment Comprehensive asthma diagnosis and management including spirometry testing, asthma action plans, medications, biologics for severe asthma, and trigger avoidance guidance.
• Sinusitis Treatment Diagnosis and treatment of acute and chronic sinusitis using MiniCAT instant CT scanner for accurate imaging, along with nasal steroid sprays, saline irrigation, antibiotics, antihistamines, and immunotherapy.
• MiniCAT Instant CT Scanner Low-radiation CT scanner for sinus evaluation that takes only 40 seconds (20 seconds for children). Allows physician and patient to review images immediately after the scan.
• Food Allergy Services Diagnosis and management of food allergies including skin testing, blood testing (IgE), oral food challenges, and development of emergency action plans including epinephrine prescriptions.
• PIDD Treatment (Primary Immune Deficiency Disease) Specialized care for Primary Immune Deficiency diseases, which affect approximately 1 in 500 individuals in the United States. Includes diagnosis, treatment planning, and ongoing management.
• Allernow Walk-in Clinic Walk-in allergy quick care clinic offering treatment for asthma, cough, sinus infections, and seasonal or perennial allergies. Available at three Tennessee locations (Weisgarber, Mt. Juliet, Hermitage) without appointments.
• Televisits Remote consultations with board-certified allergists via live two-way audio and video using desktop, laptop, or mobile device through the Healow app. Available to current patients and new patients by phone request.
• Clinical Research Studies Active clinical trials including the FLAIR Pediatric and Adult Asthma Study, NIMBLE Study (eosinophilic asthma), and VATHOS Study (investigational inhaler BFF MDI). Volunteers may receive study-related care, medication, and compensation for time and travel.
• Patient Portal Online platform allowing patients to request appointments, request prescription refills, view medical records, send messages to clinical staff, view lab results, and receive reminders.

Direct peers

• Family Allergy & Asthma: Multi-state allergy, asthma, and immunology specialty practice operating across the Midwest and Southeast. Direct peer — same specialty, similar multi-clinic model, board-certified allergist staffing, and immunotherapy-led revenue mix.
• Allergy & Asthma Associates of the Midwest: Multi-location allergy and asthma specialty practice with comparable services (skin testing, immunotherapy, asthma biologics, food allergy care). Direct peer in specialty, clinical model, and patient acquisition channels.
• US Allergy & Asthma: Specialty allergy/asthma practice platform operating multiple clinic locations. Direct peer in specialty, board-certified allergist staffing, and the use of in-clinic advanced diagnostics and immunotherapy.

Regional players

• Atlanta Allergy & Asthma: Large allergy and asthma practice concentrated in Georgia — directly overlapping AASC's Georgia footprint. Comparable specialty services (skin testing, immunotherapy, asthma management) with similar board-certified allergist staffing model.
• Carolina Asthma & Allergy: Southeast-based allergy and asthma specialty practice with similar clinical offerings (skin testing, allergy shots, asthma treatment, biologic therapy). Comparable regional multi-clinic model adjacent to AASC's footprint.
• Charleston Allergy & Asthma: Regional allergy, asthma, and immunology practice serving the Southeast. Comparable specialty focus, board-certified allergist model, and immunotherapy-centric revenue mix.

Broad incumbents

• National Jewish Health: Renowned specialty respiratory and immunology hospital and research center. Broad incumbent in the same clinical space — AASC refers complex cases to institutions of this caliber, and competes with them for severe asthma and PIDD patients in overlapping geographies.
• Cleveland Clinic: Large multi-specialty academic health system with a dedicated allergy/immunology program. Broad incumbent offering overlapping allergy, asthma, and immunology services as part of a much wider portfolio; competes for tertiary referrals.

Others

• Asthma and Allergy Foundation of America (AAFA): National patient advocacy and education organization for allergy and asthma. Ecosystem participant — not a clinical competitor, but a partner channel for patient education, awareness, and policy that benefits practices like AASC.
• Sanofi / Regeneron (Dupixent): Major biopharma manufacturers of severe asthma biologics (e.g., Dupixent, Fasenra, Nucala, Xolair) that AASC prescribes and administers. Ecosystem participant — supplier/partner relationship through the clinical research program and biologic administration services.
