He talks about how his passion developed from plays to bigger roles. He discovered a talent search in Florida that introduced him to professional managers and agents, and he won a Best Overall Child Actor award at Talent Inc. when he was a pre-teen. His early success has given him a focus in his acting career, which is to maintain his work in the film and television industries but also lead a normal life as a student.

Career Beginnings

For Griffin, his early career included some TV appearances, which gave him an education about how sets operate and how to manage his time well. Griffin states that he began taking professional acting gigs around the age of 10-11, which can be very difficult to manage, especially with remembering lines, hitting your marks, and concentrating, all while still being a kid.

However, before Cobra Kai became the focus of his work, he has experience in both television and movies. He acted in The Week Of with Adam Sandler and Chris Rock, and he has also acted in Bull and Unbreakable Kimmy Schmidt. He has also acted in New Amsterdam and has done work in true-crime television, which has taught him the value of being adaptable in his acting.

What is Griffin Santopietro Up To Now?

Griffin had the role of Anthony in the sixth and final season of Cobra Kai, which occurred in 2024 and 2025. When the show ended, he began discussing his experience balancing acting and school, and he has Yale University listed as part of his bio. He also attended events related to the show, such as the finale premiere in 2025.

Currently, he is studying Theatre and Performance Studies and English at Yale University and has been involved in theater activities at Yale University. In 2024, an article in the Yale Daily News featured a stage performance by a student at Yale University in which Griffin acted the role of a character named Con and reflected on how collaborative practices in acting can be.

Griffin Santopietro’s Physical Appearance

Griffin’s appearance has really evolved due to Cobra Kai having run for so many years. Griffin started out as a younger, chubby-faced kid, transitioning into a more mature teenager and young adult, which has allowed the show to reflect Anthony’s transition from having ‘little bro’ vibes to being able to hold his own.

Usually, he has a slender build, along with a youthful, expressive face that looks great on camera. His actual height isn’t provided in any public biography, although most sources state that he has an average height for a young male actor. In reality, his fashion style tends to be casual and clean, just like the student look he portrays online.

Net Worth

The reason why there is not a verified public figure to associate with Griffin’s net worth is that he is quite early in his career and has not reached the level where his net value would be known to the public. There are various sites where the net value of celebrities is listed, and these figures tend to be estimates based on assumptions regarding salaries and contracts that the celebrities do not disclose to the public.

One thing that is clear, however, is how a young actor like him makes money. Acting is the primary source of income, and with his credits in a successful series and guest appearances in TV shows, it makes sense that most of his money comes from there. Social media and premieres are also potential sources, even if the amounts are not publicized.

Social Media

Griffin is primarily active on Instagram, posting a variety of personal pictures, travel pictures, friends, as well as work-related updates. At the beginning of 2026, he has around half a million followers. This makes him reach his fans directly without any media coverage.

His online personality is normally calm and direct, without being overly polished. He posts some behind-the-scenes material but does not share most of the personal information that fans would like. He usually writes about the best things that happen to him instead of everyday things that happen. This fits with his idea of keeping up with both his online and real-life lives. He posts when he wants, usually about Cobra Kai milestones, cast relationships, or school experiences.

Future Prospects and Vision

The future What Griffin chooses to do next will depend on the roles that interest him after being associated with one big series for all these years. Actors who have been part of long-running series usually want some diversity, and his combination of both screen and university theater experience suggests that he could have some scope both on the big and small screens as well as on the stage.

He has talked about how acting can be unpredictable, how you have to keep showing up even if you don’t have a job lined up next. He’s a supporter of things like World Central Kitchen, so there’s a sense of values that go beyond work. If he keeps pushing himself, doing things that are a challenge for him, he can build a career that’s not based on a single hit performance.
