What Granite State Gastroenterology does
Granite State Gastroenterology is an independent, private gastroenterology and hepatology group practice headquartered in Londonderry, New Hampshire, with four additional clinic locations in Bedford, Raymond, Windham, and Berlin. The practice employs 15 staff including four board-certified gastroenterologists (Deepshikha N. Chowdhury, Laura C. Horton, Leon P. McLean, Steven Tsistrakis) and five Advanced Practice Registered Nurses and Physician Assistants. It offers diagnostic and therapeutic GI procedures—colonoscopy, upper endoscopy (EGD), capsule endoscopy, Bravo pH probe testing, PEG tube placement, and ERCP—across multiple affiliated ambulatory surgery centers (Parkland Medical Center, BASC Surgical Center, Surgical Center of New Hampshire).
The group's clinical focus spans general GI disorders, inflammatory bowel disease (Crohn's and ulcerative colitis), liver disease management including Hepatitis C treatment with direct-acting antivirals, GERD and esophageal motility disorders, and colorectal cancer screening. Procedures are performed using modern endoscopic equipment; the practice emphasizes patient comfort through sedation-based pain-free endoscopies and supplements in-person visits with telehealth appointments. Operational infrastructure runs on athenahealth (patient portal and EMR), Klara (secure messaging), and PayMyDoctor.com (billing), with Google Maps integration for patient navigation.
The practice operates on a fee-for-service revenue model, billing insurance plans including AARP, Aetna, BCBS, Cigna, Harvard Pilgrim, NH Medicaid, Tricare, Tufts, UHC, Wellnet, and others. Self-pay patients are accepted via cash, check, or credit card. GTM is sales-led via primary-care referrals and direct scheduling through phone, web, or secure messaging. Marketing is dominated by content (SEO-optimized blog, 15+ page patient education library) and reputation management through Google reviews and Facebook.
