New York Gastroenterology Associates

What New York Gastroenterology Associates does

New York Gastroenterology Associates (NYGA) is a private, for-profit gastroenterology medical practice headquartered at 620 Columbus Avenue on Manhattan's Upper West Side, founded in 2001, with operations spanning six office locations across Manhattan and Brooklyn. The practice employs a total of 51-100 staff including over 25 board-certified gastroenterologists and registered dietitians covering subspecialties such as inflammatory bowel disease, hepatology, women's digestive health, and clinical nutrition. NYGA delivers diagnostic, therapeutic, and preventive gastrointestinal services — screening and diagnostic colonoscopy, upper endoscopy, flexible sigmoidoscopy, esophageal dilation, hemorrhoid treatment (including the FDA-approved HemWell™ system and infrared coagulation), infusion therapy for IBD, and intestinal ultrasound imaging — supported by an internal pathology division (Manhattan GI Pathology) and an active clinical research function.

Revenue is generated through three streams: recurring office and telehealth consultations, one-time endoscopic and surgical procedures performed at three affiliated ambulatory surgery centers (The Endoscopy Center of New York, Carnegie Hill Endoscopy, and Manhattan Endoscopy Center), and specialized treatment lines such as HemWell™ and infusion therapy. Patient pricing is not publicly disclosed; the practice accepts insurance, with colonoscopy screening covered by most plans and patients receiving cost estimates prior to procedures. The go-to-market is direct-to-consumer, with appointments booked via phone, text, or the website across NYC's two largest boroughs.

NYGA operates as an independent private practice with no disclosed venture, private equity, or institutional investment. Growth has been driven primarily by selective acquisitions of legacy single-specialty practices — Westside Gastroenterology (March 2022) and the Erber GI Practice (January 2024) — alongside internal service-line introductions such as HemWell™ and intestinal ultrasound. Ownership of NYGA-affiliated endoscopy centers sits with individual NYGA physicians rather than the practice entity, creating a referral and procedural-revenue alignment between the practice and its affiliated surgery centers.
