Ephraim McDowell Gastroenterology offers care for those with GI issues. This includes the esophagus, stomach, small intestine, colon, liver and pancreas. We can help whether your issues are acute or chronic.

It’s important to choose the right physician for your GI issues. We have three physicians and an advanced practice provider on staff. They can diagnose and treat diseases and disorders of the GI tract and liver. The physicians can also screen for colon cancer. Thus, patients get the care they need close to home. 

The physicians completed specialized fellowship training. Because of that, they are trained in a wide range of GI services and procedures to care for patients. As a result, patients receive quality care and treatment.

Our providers offer patient-centered care. We value our patients and treat them with respect and dignity. We also listen to their concerns and involve them in decisions about their care. As a result, patients can feel at ease in our office.

We develop a treatment plan specific to each patient and their diagnosis. We provide the highest standard of care and comfort to our patients. Thus, our patients receive the best solution for their needs.
