What Middlesex Gastroenterology Associates LLC does

Middlesex Gastroenterology Associates LLC is a private, physician-owned gastroenterology and hepatology practice headquartered at 410 Saybrook Road, Suite 201, Middletown, Connecticut. Founded in 1986 and serving Greater Middlesex County for over 30 years, the practice operates across four Connecticut office locations (Middletown, Essex, Madison, Marlborough) and is affiliated with Middlesex Hospital and the co-located Middlesex Endoscopy Center. Its clinical team comprises eight board-certified gastroenterologists and hepatologists, three physician assistants, and one APRN, delivering consultations, diagnostic procedures, and treatments for digestive and liver diseases. Dr. Gregor J. Koobatian, MD, AGAF, leads the practice as Chief of the Gastroenterology Section at Middlesex Hospital.

The service portfolio centers on three blocks: clinical gastroenterology consultations covering acid reflux, GERD, IBD, celiac disease, hepatitis, pancreatic and biliary disorders; advanced endoscopic procedures including upper endoscopy (EGD), colonoscopy, ERCP, EUS, capsule endoscopy (PillCam), and motility evaluation performed at the affiliated Middlesex Endoscopy Center; and non-invasive diagnostics such as Fibroscan liver elastography, H. pylori breath testing, and hydrogen/methane breath tests for SIBO and carbohydrate malabsorption. Supporting infrastructure includes a Phreesia-powered online appointment request form, electronic patient intake, an online payment portal, and patient portal access through myhealthrecord.com, alongside eight branded colonoscopy preparation protocols (MoviPrep, GoLYTELY, MiraLAX, PLENVU, Clenpiq, SUPREP, SUTAB, Two-Day Prep).

The business model is professional-services billing against health insurance plans and self-pay patients, with no disclosed procedure-level pricing. Patient acquisition is referral-led, drawing from primary care physicians, the Middlesex Health network, and the practice's 30-year regional brand position. The practice is physician-partner owned with no identified private equity, venture, or parent-company ownership; an affiliated ambulatory surgery center (Middlesex Endoscopy Center) operates as an adjacent entity under shared physician leadership.
