About Us
The Gastroenterology, Hepatology & Nutrition team at Children’s Nebraska specializes in the diagnosis and management of a broad spectrum of liver and gastrointestinal conditions in pediatric patients, from birth through age 19. Our team is skilled in handling complex issues such as abdominal pain, constipation, food allergies and liver diseases.
We take a collaborative, multidisciplinary approach to patient care. For instance, children with food allergies or sensitivities benefit from coordinated care alongside our Allergy, Asthma and Immunology team. Our pediatric gastroenterologists and hepatologists work closely to develop personalized treatment plans that deliver the best possible outcomes.
To improve access to care, we offer services not only at our main campus in Omaha but also at locations in Lincoln, Nebraska and Sioux City, Iowa, providing families with convenient access to specialized pediatric care.
