Before going into acting, Guzman was a
mixed martial arts fighter, until his fighting license expired in 2010, plus a print and commercial model with
Wilhelmina Models and
Look Model Agency from the age of 18, when he moved to
San Francisco. He modeled for
Abercrombie & Fitch and
Reebok, as well as starred in television commercials for
Old Navy,
Gillette, among others. Coming back into the high-energy franchise, Guzman said, "The hardest thing is matching my skill level to the professional dancers who've been dancing for 25 years," adding that, "acting like I can dance is one thing, but making it believable to the audience is another. I'm training nonstop with these dancers, learning the ins and outs and everything I can to make it look like I'm as good as they are." He also credited his mixed martial arts training, "the discipline and determination I had to have for martial arts, I carry on as an actor." In 2015, Guzman starred as an extremely intelligent student, Noah Sandborn, in the titular role of
The Boy Next Door, an American
erotic psychological thriller film, opposite
Jennifer Lopez, as his teacher Claire, who he had a brief
affair with at her school, and then pursued her aggressively. Guzman explained how he prepared for the role, Guzman's first main role in a television series was the
NBC's
superhero drama
Heroes Reborn, as a continuation of
Heroes. He starred as
Carlos Gutierrez, a war hero who lives in Los Angeles with his brother Oscar and nephew José. Around the same time, he graced the cover of
DA MAN magazine in Indonesia, in a fashion‑editorial spread that highlighted his modeling roots and growing style credibility. These appearances reflect his evolution from early brand shoots for labels such as Affliction and
Reebok into editorial-led fashion representation, cementing his cross‑industry appeal during 2024 and 2025. ==Personal life==
