He is one of three children in his family – he has an older brother, Tony, and a twin sister named Molly. Their mother encouraged the boys’ interest in modeling and acting from infancy.
In fact, Andrew and Tony started modeling at six months old, and their mother “continued taking them on acting auditions” as they grew up. These early experiences in front of the camera were part of his upbringing in Pelham.
Terraciano attended the Pelham public schools. He was active in his high school community and served as senior class president of the Pelham Memorial High School class of 2021. After graduating high school, he enrolled at New York University, where he studied history and Italian.
Throughout his childhood in Pelham, Terraciano’s life was described as that of a typical suburban teenager. Local news noted that, despite their early start in modeling, the Terraciano brothers were “just two normal teenagers” enjoying school, sports and family life. His early years were shaped by a close-knit family environment in Pelham and by his early introduction to the performing arts through his mother’s support of his modeling and audition activities.
