Ross Butler stars as Zach Dempsey on "13 Reasons Why," the popular Liberty High athlete whose connection to Hannah Baker becomes part of the story revealed through her tapes. Although Zach is part of the school’s social elite, he is also shown as more thoughtful and conflicted than his status first suggests. His role places him within the group of students forced to confront how their choices affect Hannah and the people around them.
Before joining "13 Reasons Why," Butler is already building a television career through roles on series such as "K.C. Undercover" and "Teen Wolf." His earlier work introduces him to teen and young adult audiences, helping establish him as a rising actor before taking on a more serious dramatic role.
In addition to his television work, Butler appears in projects that allow him to move between comedy, action, and drama. His experience in youth-oriented television makes him a strong fit for "13 Reasons Why," while the role of Zach gives him material with greater emotional weight and moral complexity.
As "13 Reasons Why" begins, Butler brings confidence, restraint, and vulnerability to the role of Zach Dempsey. On the series, he helps explore the pressures of popularity, guilt, and responsibility within Liberty High’s social world.
