Sini Hill began acting in theater at eight. By ten, a film-loving teacher introduced her class to films like Magnolia and The Sting - and something clicked.

At a young age, she moved to New York to study Acting for Film at NYFA, and has since spent over a decade building her career across film, television, and theater. Her credits include The Blacklist, Asian Persuasion, Uncut Gems, The Sky Is Blue With Lies, King of Los Angeles, A Wilderness of Error and False Positive, among others. She has also appeared in numerous national and global commercial campaigns for brands such as Samsung, White Claw, Nick’s Ice Cream, Dannon Oikos, Cityrow, and Aveeno.

Alongside her acting career, Sini is passionate about filmmaking. Her debut short film Hustle received multiple awards at film festivals across the country, including Best Actress and Best Writing. She is attached as an Executive Producer on the upcoming feature film Deville (dir. Luca Pizzoleo), currently in production.

She will next be seen in the feature film Choices (dir. Chris Brew), set for release in 2026.

In addition to her work in film, Sini is a classically trained pianist, a lifelong dancer and trained in stage combat.
