Gastroenterology (GI)

There’s no place like CHOC for the diagnosis and treatment of children with gastrointestinal illnesses and diseases. Our gastroenterology team is committed to offering patients the very latest treatments in an environment dedicated to patient- and family-centered care.

Our physicians and other health care professionals are specially trained to treat pediatric gastroenterology patients and work closely with each child’s care team to create the best treatment plan possible. This team includes the patient, parent or guardian, subspecialist and primary care provider. Each patient’s unique treatment plan takes into consideration the child’s present and future medical and emotional needs, the family’s preferences, as well as social and ethnic considerations.
