What Atlantic Digestive Specialists does

Atlantic Digestive Specialists is a private, physician-owned gastroenterology medical practice headquartered in Somersworth, New Hampshire. Founded in 1973 by Dr. Geoffrey Clark as the first gastroenterology practice in the Seacoast area (originally as Gastroenterology Professional Association), it delivers digestive-disease care from two office locations in Somersworth and Portsmouth, NH, plus seven affiliated hospital and ambulatory surgery centers covering seacoast New Hampshire, southern Maine, and northeastern Massachusetts. Its clinical roster comprises nine board-certified gastroenterologists (Damianos, Epstein, Hyett, Kesar, Lewis, Lynch, Maher, Munot, Ruben) plus advanced practice providers and physician assistants, and the practice has been consecutively recognized on New Hampshire Magazine's Top Docs list via Castle Connolly physician voting since at least 2020.

The practice's care delivery is built around a comprehensive diagnostic and therapeutic GI service line: screening and diagnostic colonoscopy, EGD, Endoscopic Ultrasound (EUS), ERCP, esophageal manometry, pH/impedance testing, Barrett's Esophagus radiofrequency ablation (BARRX), photodynamic therapy (PDT), video capsule endoscopy (CapsoCam), liver biopsy, and breath tests for H. pylori, lactose intolerance, and SIBO. Telemedicine was added as a delivery channel in 2020 and a Transoral Incisionless Fundoplication (TIF) GERD procedure was launched in July 2023 in partnership with Wentworth-Douglass Hospital. The technology stack is conventional: a MyHealthRecord patient portal and an InstaMed payment portal, with HIPAA-compliant privacy practices; no proprietary platforms, AI/ML components, or data assets are disclosed.

Revenue is generated almost entirely through professional-services billing to insurance and patients for office consultations, screening procedures, diagnostic endoscopies, and therapeutic interventions. Routine screening colonoscopy is covered at 100% by most health plans, while diagnostic procedures carry co-insurance and deductible exposure. Patient acquisition is referral-driven via primary care physicians in the service region plus self-referrals and a community partnership with Families First Health and Support Center, which has channeled 85+ uninsured patients into free screening colonoscopies. The practice appears to be physician-owned with no parent company, no disclosed outside investment, and no public financial reporting.

Broad incumbents

• Gastro Health: One of the largest national gastroenterology platforms, PE-backed (Olympus Partners, then Audax), operating 100+ locations across multiple states. Provides direct structural comparison to Atlantic Digestive as both deliver full-service GI care including advanced procedures, but Gastro Health operates at vastly greater scale and with corporate infrastructure.
• United Digestive: Large PE-backed (Frazier Healthcare Partners) gastroenterology platform in the Southeast with 25+ clinics, 7 ASCs, and a similar physician-practice-plus-affiliated-facility model. Closest direct peer in operating model and growth-stage to Atlantic Digestive, though at much greater scale.

Direct peers

• Capital Digestive Care: Independent, multi-physician gastroenterology group in the D.C. metro area offering a comparable mix of screening colonoscopy, advanced endoscopy (EUS/ERCP), and chronic GI disease management. Closely matches Atlantic Digestive's mid-sized, multi-office, multi-physician group structure.
• Borland Groover: One of the largest independent gastroenterology practices in the Southeast, with 30+ board-certified physicians offering the full spectrum of GI services including advanced therapeutic endoscopy. Closely comparable to Atlantic Digestive in service mix and multi-physician specialty model.
• Illinois Gastroenterology Group: Multi-physician, multi-office gastroenterology specialty group in the Chicago suburbs offering a comparable full-service GI procedure menu including screening, advanced endoscopy, and chronic disease management. Direct operational analog to Atlantic Digestive.
• Peak Gastroenterology Associates: Multi-physician GI practice in Colorado Springs offering screening colonoscopy, advanced therapeutic endoscopy, and chronic GI care across multiple office locations and affiliated facilities. Similar size and structural model to Atlantic Digestive.
• Digestive Health Associates of Texas: Multi-physician GI group with 30+ providers in the Dallas-Fort Worth metro area offering a similar mix of screening, advanced endoscopy, and chronic disease management. Comparable in size and service breadth to Atlantic Digestive.

Regional players

• Connecticut Gastroenterology Associates: Multi-physician gastroenterology group in central Connecticut with comparable full-service GI offerings, but serving a different New England sub-market rather than competing directly with Atlantic Digestive in Seacoast NH.
• Concord Gastroenterology Associates: Independent multi-physician GI group in Concord, New Hampshire, providing similar services in an adjacent New England geography. Most direct regional peer in terms of state-level payer mix and patient population.

Others

• Digestive Health Physicians Association (DHPA): National trade association representing independent gastroenterology practices. Relevant as an industry context peer — its membership comprises groups of similar size and structure to Atlantic Digestive, and it serves as a key advocacy and benchmarking resource for the practice.
