Part of F.F. Thompson Hospital 

Gastroenterologists are specialists who diagnose and treat problems of the digestive organs - esophagus, stomach, liver, pancreas, small and large intestine, bile ducts and gallbladder. A Hepatologist is a specialist who specifically treats disorders of the liver. 

Our highly-trained staff at F.F. Thompson Hospital Gastroenterology provides comprehensive and compassionate care, focused on quality patient outcomes. 

Thompson offers many endoscopy procedures – a minimally-invasive procedure that uses a small instrument called an endoscope to see the inside of the digestive tract.
