Program EventsGI for Kids Scholarship
East Tennessee Children’s Hospital (ETCH) is proud to have a stand-alone endoscopy suite, which is one of the few in the country solely dedicated to children. This endoscopy suite was named in honor of Dr. Al-Tawil due to his dedication and diligence in providing excellent care to area children. The suite is supported by multiple pediatric specialists that include surgeons, anesthesiologists, intensive care specialists, radiologists, hematologists, and other specialists on call to help our team of gastroenterologists manage and care for these children.
The infusion department is located in our clinic to provide Remicade infusions and Humira treatments that reduce hospital visits and exposure to illness or disease.
