Allied Digestive Health

What Allied Digestive Health does

Allied Digestive Health is a physician-led, integrated gastroenterology and hepatology practice platform headquartered in West Long Branch, NJ, providing multi-specialty digestive health care across 60+ care centers in New Jersey and New York. The platform serves individual patients (adults seeking colonoscopy screening, diagnosis of IBS/IBD/GERD/Celiac, infusion therapy, and chronic GI disease management) and operates a parallel B2B physician-services arm through which independent gastroenterology practices integrate into ADH's network. ADH employs 200+ board-certified gastroenterologists, pathologists, anesthesiologists, nurse practitioners, and physician assistants, with 27+ acquired GI practice brands retained under the umbrella; centralized non-clinical operations (revenue cycle, HR, IT, compliance, payor negotiations, marketing) are provided by its wholly-owned managed services subsidiary, AHMSO (Allied Health Management Services Organization).

Underlying technology combines a third-party healthcare IT stack — athenahealth for patient portal and practice management, HealthMark Group for medical records requests, CRIO for clinical trial eSource/eReg/CTMS, Plumsail Forms for Open Access Colonoscopy scheduling, and ADP Workforce Now for HR — with a wholly-owned clinical research entity, AHCRO, launched in 2023 to deliver GI/hepatology trials across the network's patient population. The product surface includes the Open Access Colonoscopy program (direct-schedule screening for eligible 45+ patients across 15+ locations), ADH Total Wellness (FibroScan liver elastography, registered-dietitian nutrition counseling, and infusion therapy for biologics), and the 2026-launched RevUp Medicare-covered chronic care management program pairing patients with personal health coaches.

Revenue derives primarily from fee-for-service and value-based clinical reimbursement across the 60+ care centers, supplemented by clinical research sponsorship revenue via AHCRO and ancillary service lines (infusion, FibroScan, nutrition). The go-to-market is sales-led and acquisition-driven: ADH buys independent GI practices in the Northeast and integrates them into the AHMSO-managed network while preserving local practice branding and clinical autonomy. The legal entity is ADH, LLC (Delaware), and disclosed external capital includes SEC Form D exempt offerings by Allied Health MSO Holdco of approximately $66.6M (2024, ~$56.4M sold) and ~$6.58M (2022).

Broad incumbents

• GI Alliance: Largest PE-backed gastroenterology practice platform in the U.S., operating across multiple states with a similar physician-led roll-up model, payor leverage strategy, and ancillary service offering (research, infusion). Direct competitor for practice acquisitions and benchmarks ADH's national growth trajectory.
• Cleveland Clinic Digestive Disease Institute: Hospital-affiliated gastroenterology and hepatology program with national reputation, advanced endoscopy, and clinical research capabilities. Comparable in service breadth (advanced endoscopy, infusion, research) but operates within an integrated health system rather than a private-practice platform.

Direct peers

• One GI: Middle-market, PE-backed integrated gastroenterology platform that acquires and partners with independent GI practices. Operates with a similar decentralized, physician-autonomy-preserving model and provides payor contracting, RCM, and clinical research support analogous to AHMSO at ADH.
• US Digestive Health: PE-backed GI practice consolidator in the Mid-Atlantic/Northeast region offering multi-specialty digestive disease care with a comparable acquisition-led growth strategy. Competes with ADH for independent practice partnerships and physician recruitment in overlapping geographies.
• PE GI Solutions: Specialty physician practice management organization focused exclusively on gastroenterology, providing ancillary services and operational support to affiliated practices. Closely analogous to AHMSO's role within ADH and competes for the same independent practice partnership pipeline.

Regional players

• Atlanta Gastroenterology Associates: Large integrated GI practice operating across the metro Atlanta region with research, infusion, and advanced endoscopy programs similar to ADH's Total Wellness and AHCRO offerings. Useful comparable for GI group scale economics, though geographically non-overlapping with ADH.
• Illinois Gastroenterology Group: Midwest-based integrated gastroenterology practice offering comprehensive GI care, clinical research, and infusion services. Comparable service mix and group-practice structure to ADH though operating in a different geography.
• Digestive Health Associates of Texas: Large multi-location gastroenterology group in Texas providing clinical care, research, and ancillary services including infusion and FibroScan. Similar integrated-service, multi-specialty GI practice model though non-overlapping geographically.
