THREE VILLAGE ALLERGY & ASTHMA, PLLC

What THREE VILLAGE ALLERGY & ASTHMA, PLLC does

Three Village Allergy & Asthma, PLLC is a single-location allergy, immunology, and pulmonary medicine practice headquartered in South Setauket, New York, operating since 2012 under the leadership of Dr. Anthony M. Szema, M.D. The practice provides diagnostic and treatment services across a broad allergy and respiratory condition portfolio (asthma, allergic rhinitis, food and pet allergies, contact dermatitis, immunodeficiency, occupational asthma, and 9/11- and war-related lung injuries) to adult and pediatric patients in Suffolk County, Nassau County, Queens, and Manhattan, accepting most major insurance plans including Medicare. Core clinical offerings include FDA-approved Multi-Test Pain Control allergy skin testing (a technique in which Dr. Szema was the first U.S. allergist/immunologist to adopt), Pulmonary Function Testing, Anti-IgE (omalizumab) therapy for allergic asthma, and ALK Abello-sourced allergy immunotherapy. The practice also functions as an extension of the Stony Brook University World Trade Center Health Program's clinical Center of Excellence, providing allergy/immunology care to 9/11 responders.

Business model revenue generation is fee-for-service medical practice: insurance and Medicare reimbursement for office visits, diagnostic testing (skin testing, PFT), and treatment courses (immunotherapy injection series, omalizumab administration). The go-to-market motion is primarily referral-driven — institutional partners (Stony Brook WTC program, Northport VA, John T. Mather, St. Charles, and Hofstra academic appointments) generate specialist referrals, with complementary patient-acquisition from physician reputation channels including Super Doctors listings and medical publication contributions (e.g., Scientific American). Patient onboarding is supported through a standard Athenahealth patient portal and downloadable intake and referring-doctor forms.

Structural positioning is niche and differentiated by credentialing rather than scale: the practice is a single-physician-led PLLC with five total employees, no disclosed funding rounds, no parent company, and no second office location. Its defensibility rests on a non-replicable credentialing profile held by one individual, which simultaneously represents an owner-key-person risk to continuity.

Direct peers

• ENT and Allergy Associates: One of the largest otolaryngology and allergy practices in the New York tri-state area with 40+ office locations. Closest direct comparable to Three Village because it combines adult/pediatric allergy, immunology, and pulmonary-style services across the same Long Island / NYC geography.
• Allergy Partners: National allergy, asthma, and immunology practice network with 100+ board-certified allergists across the U.S. Operates the same single-specialty clinical model (skin testing, immunotherapy, biologics) that Three Village uses, but at multi-site scale.

Others

• Asthma and Allergy Foundation of America (AAFA): Patient advocacy and education nonprofit serving the same allergy/asthma population. Not a clinical peer, but adjacent ecosystem participant that drives patient awareness and referral traffic to specialty practices like Three Village.

Broad incumbents

• Family Allergy & Asthma: Multi-state allergy and asthma practice with research, infusion, and immunotherapy services. Comparable clinical service mix to Three Village but operates a much broader footprint and centralized administration.
• Northwell Health: Large New York health system offering allergy, immunology, and pulmonary specialty care across Long Island and the five boroughs. Provides the integrated-system competitor against which small specialty practices like Three Village compete for in-network referrals and physician talent.
• Mount Sinai Health System: Academic health system with a Department of Allergy and Immunology and National Jewish-style respiratory programs. Competes for higher-acuity allergy, immunodeficiency, and severe asthma referrals in the same NYC metro area.
• Stony Brook Medicine: Academic medical center that runs the WTC Health Program and employs Dr. Szema as a consultant. Operates adjacent allergy/pulmonary services in Suffolk County and is both a partner and indirect competitor for the same patient base.

Emerging players

• Asthma & Allergy Center (Bellevue, NE and affiliates): Mid-size regional allergy and asthma practice with multiple providers and sites. Operates a comparable business model (single-specialty, allergen immunotherapy, biologic infusions) at slightly larger scale than a solo practice like Three Village.
