GastroenterologyAfter completing college and medical school, a gastroenterologist receives three years of training in internal medicine and an additional two to three years of specialized training in the diagnosis and treatment of diseases of the digestive system, including the esophagus, stomach, small and large intestines (colon), liver, pancreas, and gall bladder. All of our physicians are certified by the American Board of Internal Medicine and have fulfilled the requirements for the subspecialty Board of Gastroenterology.

A complete gastrointestinal evaluation usually involves an interview, physical examination, and specialized studies such as x-rays and/or other imaging studies. Endoscopic procedures involve the passage of flexible lighted instruments to inspect the inside of the digestive tract. Endoscopic procedures may be used to remove polyps, dilate strictures, stop internal bleeding, or remove stones from the bile duct.

Our patients are usually referred to us by another physician or provider for a specific evaluation or treatment. When this is completed, we will correspond with that physician or provider, summarizing our findings and recommendations. We may assume care of a specific digestive problem, but we will usually refer you back to your physician or provider for ongoing care. We see adult patients 18 and older. All of our doctors are on the staff of Saint Alphonsus Regional Medical Center, St. Luke’s Regional Medical Center, and St. Luke’s Meridian Medical Center.
