Early Life and Family Background
Griffin Santopietro was born on January 5, 2005, in Portland, Maine. He grew up in Connecticut with his parents, John and Kathy Santopietro, and his two brothers, Max and Beckett. His brother Max is also an actor who appeared on FBI: Most Wanted, and his younger brother Beckett keeps a lower profile. His family played a big role in supporting his dreams from a very early age. His mother, Kathy, has been especially vocal about how proud the family is of everything Griffin has achieved.
From a young age, Griffin loved performing in school plays. His passion for acting grew stronger every year. When he was ten years old, he moved to Charlotte, North Carolina, where he joined Acting Out Studio. That decision changed his life. He entered a talent competition called Talent Inc. in Orlando, Florida, and won the Best Overall Child Actor Award. That victory was the starting point of his professional acting career.
Acting Career: The Early Steps
Griffin took his first steps into professional acting after winning the talent competition at age ten. He signed with the Osbrink Agency in Los Angeles and the Carson Adler Agency in New York. His first on-screen role came in 2016 when he appeared as Scott Brantner in the TV series Homicide Hunter. It was a small role, but it gave him his first real experience on a professional set.
In 2018, Griffin landed a role in the Netflix comedy film The Week Of, starring Adam Sandler, Chris Rock, and Steve Buscemi. He played a character named Jeddy. Working alongside such experienced actors at a young age taught him a great deal about professionalism and the craft of acting. He also appeared in guest roles on popular TV shows such as Unbreakable Kimmy Schmidt on Netflix, Bull on CBS, and New Amsterdam on NBC.
Breakthrough Role: Anthony LaRusso in Cobra Kai
Griffin’s biggest break came when he was cast as Anthony LaRusso in Cobra Kai, the Netflix sequel series to the classic 1984 film The Karate Kid. He joined the show in its very first season in 2018, when he was just 12 years old. Anthony LaRusso is the son of Daniel LaRusso, played by Ralph Macchio. In the early seasons, Anthony was a background character who spent most of his time playing video games and showing no interest in karate.
Everything changed in Season 4. The writers gave Anthony a much bigger role. He became a middle school bully who targeted a new student named Kenny Payne. This storyline gave Griffin the chance to show a different and more complex side of his acting skills. Fans who once found Anthony annoying began to understand him better. By Season 5, Anthony joined Miyagi-Do Karate, and Griffin had to learn real karate moves and work with stunt coordinators to perform fight scenes. He appeared in 34 episodes across all six seasons, with the show ending in 2025.
Anthony LaRusso’s Character Growth
One of the most talked-about parts of Cobra Kai was how much Anthony LaRusso changed over the course of the show. At the start, he was spoiled and mean. He bullied Kenny without thinking about the harm he caused. But the writers slowly showed viewers why Anthony acted that way. He was under pressure from his friend group and struggling with his own identity. Griffin spoke about this in an interview, saying that Season 4 did a good job of showing that Anthony was not just a jerk but a kid dealing with real pressures.
By the final season, Anthony was competing in the Sekai Taikai, one of the biggest karate tournaments in the Cobra Kai world. His journey from a lazy, selfish boy to a motivated young fighter with real values was one of the most rewarding character arcs in the series. Griffin handled this growth with skill and maturity, earning praise from fans and critics. Watching him transform on screen showed just how much he had grown as an actor since joining the show at age 12.
Education at Yale University
While many young actors choose to focus completely on their careers, Griffin made a bold choice. He enrolled at Yale University in New Haven, Connecticut, one of the most prestigious Ivy League schools in the United States. He is majoring in Theatre and Performance Studies and English. On the Yale Class of 2028 Instagram page, he shared his excitement about joining the university, saying he had been acting for seven years and was looking forward to collaborating on campus.
Griffin has not let his education slow down his career, and he has not let his career get in the way of his studies. In 2024, the Yale Daily News featured a stage production in which Griffin performed, showing that he was actively involved in theater on campus. He attended Suffield Academy for high school, where he once described his teachers as people who really understood him. His commitment to formal education alongside a growing Hollywood career makes him stand out from most young actors in the industry today.
