Dr. Garrett Zella grew up in Texas then California, before he and his family moved to Massachusetts in the middle of high school. He attended Brandeis University to obtain his B.S. in biology, followed by medical school at Tufts University School of Medicine. He remained in the Tufts system, completing his residency in pediatrics at the Tufts Children's Hospital at Tufts Medical Center. He then moved to MGH where he completed his fellowship in pediatric gastroenterology and nutrition. During fellowship, he began his research in the microbiome as it related to inflammatory bowel disease, which he continued into his staff position there starting in 2008. He continued that work for 2 more years, before transitioning to an Associate Director of the pediatric residency program. He cherished his involvement with the residents but in 2012 narrowed his focus, becoming one of the Assistant Directors of the pediatric GI fellowship. Dr. Zella has acquired a clinical focus in treating GI disturbances in neurologic disease as part of the Dup15q Center (helping to treat children with isodicentric duplication of chromosome 15) and helping to care for many children with Angelman and Williams syndromes in collaboration with the pediatric neurology division. In 2013, he accepted a position at Tufts Children's Hospital with opportunities in increased leadership and education both in the division of Pediatric GI and at the medical school.
