NOAH Clinics' website describes itself as the largest hyperbaric oxygen therapy facility in New York City, located at 900 First Avenue (E 51st Street). Patients breathe 100% oxygen in pressurized chambers. Stated indications include Long COVID symptoms and fatigue, sports injuries and athletic recovery, surgical wound recovery (plastic and orthopedic), neurological conditions, chronic inflammatory conditions, radiation and chemotherapy damage, complex wounds and infections, erectile dysfunction, migraines, and fibromyalgia. The practice operates as a concierge model providing individualized, high-touch support and coordinates care with patients' existing medical teams rather than replacing them. The clinic's stated mission: 'we pick up where the rest of medicine leaves off.'
