The Pioneers Center for Digestive and Liver Disease offers care for patients with all types of digestive diseases and conditions. We offer three specialties in one facility including gastroenterology, hepatology and internal advanced endoscopy. We are the only full-service, accredited digestive health facility in the Imperial Valley.

Our advanced technology means patients benefit from reduced procedure times closer to home. We offer the security and comfort of having a procedure performed in a hospital environment given our affiliation with the Pioneers Memorial Hospital District.

  • Acute and chronic liver disease including hepatitis and cirrhosis
  • Abdominal pain and/or bleeding
  • Bariatric endoscopy
  • Colon Cancer
  • Gastroesophageal reflux disease (GERD)
  • Heartburn
  • Inflammatory bowel disease
