Our Mission

Digestive Health Institute aims to serve its community by providing excellent gastrointestinal care

Since 1998, we’ve been working to serve our community. Digestive Health Institute was established to provide distinctive gastrointestinal and liver disease care for the people of central Michigan. We aim to give our patients the highest level of care while simultaneously maintaining both compassion and professionalism. Our team is committed to finding the latest innovations in gastrointestinal medicine and how technology can be best used to provide effective treatment to our patients.
