National Allergy & ENT

What National Allergy & ENT does

National Allergy & ENT is a private, multi-location medical practice headquartered in the Charleston, South Carolina metro area providing integrated allergy, asthma, ear/nose/throat (ENT), and immune deficiency care to adult and pediatric patients. Founded in 1961 according to firmographic data, the practice operates four clinical offices (North Charleston, Mount Pleasant, West Ashley, and Moncks Corner) staffed by three board-certified allergists (Dr. John Ramey, Dr. Patricia Gerber, Dr. Ned Rupp), at least one ENT physician, and a nurse practitioner (Morgan Hatfield Peters, FNP). Clinical capabilities span allergy skin testing, patch testing, nasal endoscopy, immunotherapy, asthma action planning, and ENT services addressing hearing, breathing, smelling, tasting, speaking, and swallowing issues.

The practice's core technology stack is clinical rather than software-based: physician expertise plus diagnostic instrumentation (nasal endoscope, skin and patch testing equipment) delivered through in-person visits and a Virtual Visits telemedicine channel. Distinctively, National Allergy & ENT has operated an in-house Clinical Research Studies program for over 20 years, conducting trials in asthma, allergic rhinitis, eczema, chronic urticaria, food allergies (peanut, milk, egg), chronic sinusitis, nasal polyps, and migraine headaches, with results published in medical literature; it operates as a Clinical Research Network Member with a dedicated research facility in North Charleston and dedicated sponsor/CRO liaison infrastructure. Patient-facing infrastructure includes a third-party Patient Portal (eClinicalWeb), an active content blog authored by providers, and social media presence on Facebook, YouTube, and Instagram.

Revenue is generated through fee-for-service medical billing to insurance and patients for office consultations, allergy testing, immunotherapy injections, asthma management, and ENT procedures; a patient-facing Pay Your Bill portal and Financial Services desk handle collections. The practice acquires patients through direct-to-consumer channels (organic search, blog, social media), patient reviews, and primary care referrals, and monetizes its research program through study sponsors and CROs. Pricing is not publicly disclosed and no external funding rounds, private equity ownership, or parent company affiliations are evidenced in the available data.
