Our Services

The providers of CHPG Gastroenterology Parker treat adult and senior patients. They are fully capable of handling multiple conditions affecting your GI tract, including the esophagus, stomach, intestines, liver, and pancreas.

For many patients, their discomfort can be attributed to routine concerns that are easily treated. However, it is important to understand what is really happening with your health. To properly understand the underlying conditions, additional diagnostic testing may be necessary. Routine screenings help to catch diseases and disorders early, creating better outcomes for our patients, as well as reducing unnecessary treatments. Once the symptoms have been identified, it is easier to select the screening technology that will be least invasive and most effective in determining a specific condition and tailored treatment plan.

Our experts can recommend an individually tailored treatment plan for digestive and gastrointestinal issues.
