Who is Griffin Santopietro?

Griffin Santopietro is a young American actor who landed a recurring role in one of Netflix’s most popular original series while still in middle school.

His character, Anthony LaRusso, is the son of Daniel LaRusso, the protagonist of the original Karate Kid films.

He made his professional acting debut several years before Cobra Kai, appearing in episode-based TV work and feature films alongside major Hollywood names.

Griffin has worked on screen with Adam Sandler in the 2018 Netflix film The Week Of and alongside Ralph Macchio across all six seasons of Cobra Kai.

He also played guest roles on CBS’s Bull and NBC’s New Amsterdam.

Beyond acting, Griffin enrolled at Yale University in 2024 to study Theatre and Performance Studies, balancing his academic life with the demands of his entertainment career.

Early Life of Griffin Santopietro

His older brother Max Santopietro is also an actor, with a credit on FBI: Most Wanted. His younger brother, Beckett, has kept a lower profile.

The family’s home base in West Hartford, Connecticut, stayed central to Griffin’s upbringing even as his career pulled him toward New York and Los Angeles.

Griffin discovered acting through school plays and quickly found it was something he wanted to pursue long-term.

In an interview published on his official website, he recalled: “the minute I finished performing in my first school play I wanted to do this forever.”

That early enthusiasm led his family to support a more serious path. Griffin moved through competitive acting programs before landing professional representation on both coasts.

The school’s website quoted him saying: “Suffield has already shown me how flexible a school can be, and my teachers really get me.

I have learned something different from all of them.” After graduating, he enrolled at Yale University in New Haven, Connecticut, in 2024.

Griffin Santopietro Career

Griffin Santopietro began his professional acting career as a child in Connecticut and North Carolina.

His path from school plays to Netflix was built over several years of competition, training, and early TV work.

Early Career and First Roles (2015–2017)

Griffin’s acting journey started in earnest at age 10 when he won the Best Overall Child Actor Award at Talent Inc. in Orlando, Florida.

That competition win opened doors to professional representation. He went on to sign with Osbrink Agency in Los Angeles and Carson Adler Agency in New York.

His first professional screen credit came in 2016 on the Investigation Discovery series Homicide Hunter: Lt. Joe Kenda.

That early credit gave him a foothold in television, followed by a guest role on Netflix’s Unbreakable Kimmy Schmidt.

His theater credits from this period include productions of Clybourne Park, School of Rock, and Cobweb Dreams.

That stage work ran alongside his screen appearances throughout his early teens.

Cobra Kai and Breakthrough (2018–2021)

Griffin joined Cobra Kai in its first season in 2018 at age 13. His character, Anthony LaRusso, is the younger son of Daniel LaRusso, played by Ralph Macchio.

In the early seasons, Anthony appeared as a background presence in the LaRusso household, often seen playing video games or eye-rolling his way through family scenes.

That same year, Griffin appeared in the Netflix film The Week Of alongside Adam Sandler and Chris Rock.

The film gave him feature film experience alongside two of comedy’s biggest names.

His Cobra Kai role stayed limited through Season 2 and Season 3, with Anthony largely absent or sidelined.

Season 3 saw him return in just one episode, “Miyagi-Do,” before a significant expansion came in Season 4.

Expanded Role and Later Seasons (2022–2025)

Season 4 of Cobra Kai, released in December 2021, gave Anthony a full storyline for the first time.

The arc revealed that Anthony had been bullying Kenny Payne, a new student at his school.

That storyline subverted the show’s themes by making Daniel LaRusso’s son the bully rather than the victim, mirroring Daniel’s own experiences in the original Karate Kid films.

In a January 2022 interview with Looper, Griffin spoke about the season’s direction: “I thought it was a really interesting way to go, where you put Daniel’s son in a bully situation of being the bully instead of the victim like Daniel was.”

Season 5 saw Anthony face the consequences of his actions and begin to shift course.

By Season 6, he had joined Miyagi-Do Karate and trained under Robby Keene, completing a full character redemption arc.

Griffin appeared in 34 episodes of the series across all six seasons, making him a consistent part of the cast from start to finish.

The sixth and final season released across three parts: Part 1 in July 2024, Part 2 in November 2024, and Part 3 in February 2025, concluding the series.

Griffin appeared in official promotional images for Season 6 alongside Courtney Henggeler, Owen Morgan, and Nathaniel Oh.

Other Television Work

Alongside his Cobra Kai run, Griffin appeared in a 2019 episode of CBS’s Bull, playing the character James Donovan.

In 2021, he guest-starred on NBC’s New Amsterdam as Linus Wilding. Both roles gave him experience outside the Karate Kid universe in contrasting genres, legal drama and medical drama respectively.
