Thea Rose was born in Indianapolis and moved to Los Angeles with her mother as an infant. She started booking commercials at the early age of four years old, and started auditioning for film and television soon thereafter. At around twelve years old, she took a break from acting to focus on school and became very involved in her middle school and high school's theatre departments. She moved on to attend University of Texas at Austin to pursue a Radio-Television-Film degree. She is now currently locally represented and a working actress in Austin, Texas.
