Griffin Santopietro Age: How Old is the Cobra Kai Star?

Griffin Santopietro age is 20 years old as of January 2026. He was born on January 5, 2005, in Portland, Maine, United States. This makes him a Capricorn, known for traits like ambition, discipline, and maturity—qualities that shine through in his acting career.

When Griffin started filming Cobra Kai’s first season, he was just 12 years old. Over the course of six seasons, fans watched him grow from a child actor into a mature young professional. His age has been a significant factor in his authentic portrayal of Anthony LaRusso, Daniel LaRusso’s son.

Griffin’s birthday falls on January 5, meaning he shares his birth month with other talented Capricorns in the entertainment industry. As a 20-year-old in 2026, he stands at the threshold of even greater opportunities in Hollywood.

Early Life and Family Background

Griffin Santopietro was born in Portland, Maine, but didn’t stay there for long. His family moved to Connecticut when he was young, where he spent most of his childhood years. He also lived briefly in Charlotte, North Carolina, where his acting career truly began.

Griffin’s parents are John and Kathy Santopietro, who have been incredibly supportive of his acting dreams. He grew up in a close-knit family with two brothers. His older brother, Max Santopietro, is also in the entertainment industry, working as an actor and talented singer-songwriter. His younger brother, Beckett, completes the Santopietro trio.

Growing up in Connecticut provided Griffin with stability while pursuing his Hollywood dreams. His family prioritized education alongside acting, ensuring he maintained a normal childhood despite early fame.

How Griffin Santopietro Started Acting

Griffin’s journey into acting began with school plays at Charlotte Preparatory School. What started as casual participation in drama classes quickly revealed his natural talent for performance.

At age 10, Griffin won the Best Overall Child Actor Award at Talent Inc. in Orlando, Florida. This prestigious recognition became the catalyst that launched his professional acting career. The award opened doors to talent agencies and casting directors.

Griffin trained extensively to hone his craft. He attended private coaching sessions at Joshua LeBar Studios, MN Acting Studio, and Alisa Reyes Studio. Later, he enrolled at the renowned Stella Adler Studio to deepen his understanding of method acting and character development.

His dedication paid off when he landed his first professional role at age 11 in the television documentary series “Homicide Hunter: Lt. Joe Kenda,” where he played Scott Brantner.

Griffin Santopietro’s Breakthrough: Cobra Kai

Griffin’s career-defining moment came when he was cast as Anthony LaRusso in Netflix’s Cobra Kai in 2018. The series, a continuation of the iconic Karate Kid franchise, became a global phenomenon.

Initially, Anthony was a minor character—Daniel LaRusso’s spoiled, tech-obsessed son who showed no interest in karate. Griffin appeared in limited scenes during the first three seasons. However, everything changed in Season 4.

The writers expanded Anthony’s role dramatically, transforming him from a background character into a central figure. Anthony became a middle school bully who tormented Kenny Payne, leading to serious consequences. This storyline gave Griffin the opportunity to showcase his range as an actor.

By Season 5, Anthony had joined Miyagi-Do Karate, learning from Robby Keene as his mentor. Griffin had to undergo physical training and learn karate choreography, adding a new dimension to his performance.

The final season (Season 6) aired in 2024-2025, featuring Anthony competing in the Sekai Taikai international tournament. Griffin filmed 34 episodes across all six seasons, making him one of the show’s core cast members.

Griffin has kept his personal life extremely private. He hasn’t posted about any romantic relationships on social media, nor has he been photographed with anyone who appears to be a girlfriend.

Whether Griffin is single or in a private relationship remains unknown. His decision to keep this aspect of his life away from public scrutiny shows maturity and professionalism.

Physical Transformation and Health Journey

Fans of Cobra Kai noticed Griffin’s significant physical transformation over the show’s six seasons. He experienced noticeable weight loss between seasons, leading to speculation about his health and fitness routine.

Griffin currently weighs approximately 121 pounds (55 kg) and stands 5 feet 8 inches (173 cm) tall. His transformation appears to be natural growth and development as he matured from age 12 to 20.

His lean physique became particularly important in later Cobra Kai seasons when Anthony began training in karate, requiring Griffin to perform fight choreography and stunts.

Acting Style and Professional Development

Griffin’s acting approach is characterized by subtlety and emotional authenticity. He doesn’t rely on exaggerated gestures or over-the-top expressions. Instead, he uses nuanced facial expressions, voice modulation, and timing to convey emotion.

This restrained style makes his performances feel genuine and relatable. It’s particularly effective in Cobra Kai, where Anthony’s character arc required showing internal conflict and gradual transformation.

Working alongside veteran actors like Ralph Macchio, William Zabka, and Martin Kove provided Griffin with invaluable mentorship. He has spoken about how Ralph Macchio, in particular, taught him professionalism and the importance of preparation.

He occasionally interacts with fans through comments and shares appreciation for the Cobra Kai community. His social media reflects his values: education, family, friendship, and professional growth.

Working with the Cobra Kai Cast

Griffin’s experience on Cobra Kai extended beyond acting—it became a formative part of his teenage years. He spent eight years filming alongside the same cast, creating deep bonds.

Ralph Macchio became a mentor figure to Griffin, teaching him about the entertainment industry’s challenges and rewards. Courtney Henggeler and Mary Mouser, who play his on-screen mother and sister, also provided guidance.

Griffin celebrated his 18th birthday with cast members at Top Golf, an experience he described as one of the best days working on the project. These relationships demonstrate the genuine family dynamic among the Cobra Kai cast.

Working with William Zabka, Martin Kove, and Thomas Ian Griffith exposed Griffin to different acting techniques and generations of performers. This diverse experience enriched his development as an actor.

Character Evolution: Anthony LaRusso

Anthony LaRusso’s character arc is one of Cobra Kai’s most significant transformations. Griffin played Anthony across three distinct phases:

• Phase 1 (Seasons 1-3): Anthony appeared as a spoiled, tech-obsessed kid with minimal screen time. He represented modern youth disconnected from traditional values like karate.
• Phase 2 (Season 4): Anthony became a bully, tormenting Kenny Payne at school. This storyline showed consequences of privilege and lack of guidance. Griffin convincingly portrayed Anthony’s cruelty and eventual remorse.
• Phase 3 (Seasons 5-6): Anthony joined Miyagi-Do, learning from Robby Keene and participating in the Sekai Taikai. He transformed from victim to warrior, completing a redemption arc.

Griffin’s ability to navigate these dramatic shifts demonstrates his range and emotional intelligence as an actor.

Awards and Recognition

While Griffin hasn’t won major entertainment awards yet, his achievements are noteworthy:

• Best Overall Child Actor Award at Talent Inc., Orlando (Age 10)
• Critical acclaim for his portrayal of Anthony LaRusso
• Featured at Variety’s Power of Young Hollywood event (2024)

At Yale, Griffin studies dramatic literature, performance theory, directing, and theatrical history. He’s surrounded by fellow students who share his passion for the arts, providing an intellectually stimulating environment.

Balancing Ivy League academics with professional acting requires exceptional time management. Griffin has successfully navigated both worlds, filming Cobra Kai’s final season while completing coursework.

His Yale experience provides networking opportunities with future directors, writers, and producers. It also offers a backup plan if acting opportunities diminish—though that seems unlikely given his trajectory.
