I hadn’t been in in almost two years and he was still up to date with what we went over on my last visit and asked great follow up questions. And ON TIME! I did not feel like a number to him. Also, this may just be me, but I appreciate the old school use of pen and paper to take notes while making eye contact. He wasn’t sitting there staring at the screen and typing away. I’m sure he used a laptop after he walked out, but was sure nice to be looked and spoken to while questions being asked.

He performed more of a physical on me than I got from my GP recently. When I asked him about any liver issues he said stay put and I will go look at your recent blood work. When he cam back he said all looked good, which make me very comfortable. When I told him I was concerned on weight gain he has recommend a dietitian to work with me.

About Gateway Gastroenterology

At Gateway Gastroenterology in Chesterfield, Missouri, we specialize in digestive health and liver disease. Our board-certified gastroenterologists and advanced nurse practitioners provide consultations and services in a friendly, clear and understandable way to provide you with the best possible care. It’s one of the reasons why our physicians have been recognized as BEST DOCTORS by the St. Louis Magazine.

Our highly-trained physicians specialize in diagnosing and treating a wide range of gastrointestinal conditions, including acid reflux, irritable bowel syndrome (IBS), inflammatory bowel disease (IBD), and liver disease. We work together as a group; however, each patient is cared for by a single gastroenterologist. Continuity and trust is built by maintaining stable and long-lasting relationships. For emergencies, a Gateway gastroenterologist is available to answer your call.

In addition to patient care at our main office in Chesterfield, Gateway Gastroenterology performs colonoscopy and upper endoscopy procedures at Gateway Endoscopy Center (Saint Louis), Saint Louis Multi-Specialty Surgery Center (Ballwin), and St Luke’s Hospital (Chesterfield). The team performs diagnostic tests like capsule endoscopies, breath tests, and infusion services right in our main office. Ask about Saturday hours at Gateway Endoscopy Center for routine procedures.

We are preferred providers on many insurance plans, and our experienced administrative staff is here to help you with questions on reimbursement. At Gateway Gastroenterology, patients come first. Please contact us today and let us partner with you in understanding your digestive health.
