GI Alliance of Illinois

What GI Alliance of Illinois does

GI Alliance of Illinois, PLLC is a physician-led gastroenterology practice formed in July 2022 through the consolidation of four independent Illinois groups — Digestive Disease Consultants, Hinsdale Gastroenterology Associates, Illinois Gastroenterology Group, and South Suburban Gastroenterology (which first joined the GI Alliance network in July 2021). It operates as a subsidiary of GI Alliance, the nation's largest independent gastroenterology services organization, representing 1,000+ providers and 590+ gastroenterologists across 10 states. The Illinois entity operates eight clinical locations spanning the Greater Chicago area (Arlington Heights HQ, Gurnee, Libertyville, Highland Park, Glenview, and Lake Bluff), including two dedicated endoscopy centers (North Shore Endoscopy Center, Glen Endoscopy Center) and two dedicated clinical research facilities (Gurnee Research, Glenview Research) supporting the GI Alliance of Illinois Research Institute.

The practice delivers comprehensive diagnostic and therapeutic gastroenterology services, including colonoscopy, EGD, capsule endoscopy, ERCP, EUS, FibroScan liver elastography, hemorrhoid banding (CRH O'Regan system), advanced interventional procedures (TIF, Barrx, SpyGlass cholangioscopy, RFA, luminal stent placement), as well as infusion therapy, nutrition and wellness counseling, and virtual telemedicine consultations. A clinical trials program operates across Phase 1–4 studies for Crohn's Disease, Ulcerative Colitis, Celiac Disease, C. Diff, and Eosinophilic Esophagitis. Patient-facing digital infrastructure includes a third-party patient portal and an online bill-pay platform (ModMed Cloud).

Revenue is generated primarily through insurance reimbursements for professional services — the practice is in-network with Aetna, Blue Cross Blue Shield, Cigna, Cigna Healthspring, Coventry, Humana, Meridian, PHCS, and United Healthcare — supplemented by per-visit patient co-pays, self-pay arrangements, and clinical trial research revenue. Go-to-market is direct-to-patient via phone scheduling (855-455-4278), online appointment requests, physician referrals, and organic search, with content marketing and SEO-driven educational content supporting top-of-funnel patient acquisition. The practice has been recognized as a Castle-Connelly Top Rated Physicians Group in Illinois and reports 8,500+ patient reviews.
