Kelley Mack, best known for playing Addy in The Walking Dead, has died at 33. Her passing on August 2 came after being diagnosed with glioma of the central nervous system, as confirmed by both her obituary and a post shared to her Instagram. According to the statement, she died peacefully, surrounded by family.
Born Kelley Klebenow in Cincinnati, Ohio, she stepped into the spotlight with roles in Chicago Med, 9-1-1, and indie films like Broadcast Signal Intrusion and Delicate Arch. She also appeared in national commercials for brands like Dr. Pepper, Ross, and Rakuten—the latter alongside her mother. Beyond acting, she had a background in cinematography and lent her voice to projects including Spider-Man: Into the Spider-Verse, where she voice-matched Gwen Stacy.
Her creative spark was evident from a young age, starting with a birthday video camera that inspired her passion for storytelling. Over the years, she built a solid reputation in the industry, admired not just for her talent but also her warmth and collaborative spirit.
In the sections ahead, we’ll take a closer look at the family behind the actress—her parents, her siblings, and the support system that remained close through every stage of her life.
Kelley Mack’s Parents: Born Into a Family That Nurtured Creativity
Kelley Mack was born on July 10, 1992, in Cincinnati, Ohio, to Kristen and Lindsay Klebenow—a couple whose support would shape much of her artistic path. Raised in a home where creativity wasn’t just encouraged but lived daily, Kelley grew up alongside two siblings, Kathryn and Parker, in a close-knit household where storytelling, performance, and expression were all part of the rhythm of family life.
Kelley Mack was of mostly German descent, with additional Finnish and Scottish ancestry.
Her mother, Kristen, shared more than just maternal pride—she shared the page. The two co-wrote several feature-length screenplays together, including On The Black, a period baseball drama drawn from Kristen’s own parents’ college years at Ohio University. Kelley’s deep love for screenwriting and character-building was something she and her mother didn’t just talk about over coffee—it was something they built together.
Her father, Lindsay, maintained a quieter presence, but his stability and constant support anchored the family. Whether Kelley was acting, writing, or navigating the ups and downs of Hollywood, her parents remained a steady part of her world.
Her Brother, Parker Mack, Found His Own Spotlight
Kelley’s younger brother, Parker Mack Klebenow, is no stranger to the entertainment world either. Born in St. Louis and raised alongside Kelley, Parker started acting at just six years old and eventually carved his own place in television with standout roles in Chasing Life and MTV’s Faking It.
But acting was only one of his creative lanes. Parker is a musician with years of piano and drum training, a baritone singer, and a songwriter who picks up songs by ear. He once played in a band called Bruner 17 and has balanced his artistic life with a competitive edge—boxing, weightlifting, and playing tennis in USTA tournaments since his teens.
Though they chose different corners of the industry, Kelley and Parker’s bond was rooted in the same foundation: a family that valued imagination, discipline, and shared creative passion.
