Ascension St. Vincent Pediatric Gastroenterology has been providing compassionate care to children for over 140 years. More than 20 years ago, a group of pediatric specialists began working at St. Vincent with a goal of providing tertiary-level pediatric care in a setting that reflected and advanced the core values of St. Vincent. The success of these physicians led to the building of a special place meant to focus on the unique needs of children and their families: Peyton Manning Children’s Hospital. 

The hospital is staffed by more than 100 highly experienced pediatric specialists along with experienced pediatric nurses, child life specialists, chaplains, and other health professionals with a multidisciplinary and collaborative approach to family-focused care. The health and well-being of each child is their top priority.

A Romanian native, Dr. Zavoian graduated with his medical degree from the Carol Davila University School of Medicine in Bucharest. After relocating to the United States, he completed a research fellowship at the University of Virginia. He then went on to complete his residency in pediatrics at Flushing Hospital Medical Center, and his fellowship in pediatric gastroenterology, hepatology, and nutrition at the University at Buffalo in New York.

Following his training, the doctor attained board certification in pediatrics and pediatric gastroenterology through the American Board of Pediatrics (ABP). The mission of the ABP is to advance child health by certifying pediatricians who meet standards of excellence and are committed to continuous learning and improvement.

In order to stay up to date in his field, Dr. Zavoian remains an active member of several professional organizations, including the North American Society for Pediatrics Gastroenterology, Hepatology and Nutrition, the American Gastroenterology Association, the American College of Gastroenterology, the American Medical Association, and the New York Society for Gastrointestinal Endoscopy. His work has been published in peer reviewed journals and presented at local and national meetings.

Pediatric gastroenterology developed as a subspecialty of pediatrics and gastroenterology. It is concerned with treating the gastrointestinal tract, liver, and pancreas of children from infancy until age eighteen. Pediatric gastroenterologists evaluate and offer treatment plans for any kind of chronic stomach issues including abdominal pain, vomiting, diarrhea, failure to gain weight, feeding problems, constipation or dietary issues.

Spending a lot of his free time with his three young children, Dr. Zavoian enjoys nature walks, and is an avid reader of science and technology and a technology hobbyist.
