About Us

The Pediatric Gastroenterology, Hepatology, and Nutrition team is committed to delivering a full range of highest quality, compassionate, up-to-date, state-of-the-art, multidisciplinary, and personalized care for pediatric patients with gastrointestinal disorders. Our patients include infants, college students, and everyone in between.

From initial testing and diagnosis through long-term disease management, our specialty-trained team includes physicians, nurses, psychologists, social workers, and dieticians who partner with families to provide patient-tailored and well-rounded care.

Aside from direct patient care, our medical practitioners also provide consultations to community physicians on basic to complex gastrointestinal and nutritional problems, including common gastrointestinal, nutritional, and hepatic problems of childhood, such as abdominal pain, chronic diarrhea, vomiting, and constipation.  

As the only academic medical center on the west coast of Florida, we are able to provide cutting-edge treatment, technology, and research.
