Alanna Masterson
Known for her role in The Walking Dead, Alanna has been a Scientologist since birth. She was born into the Scientologist family with Danny and Christopher Masterson, her siblings. At the age of 15, she completed her first course in Scientology, and every year since she continues to learn about the Church and takes more classes. Because their father has cut his ties with the church, they’re all estranged from him, completely ruining their relationship with one another (Yahoo).
