Mack made her mark in Hollywood through both on-screen acting and voice-over work. She gained widespread recognition as Addy in The Walking Dead and later played Penelope Jacobs in Chicago Med.
She also appeared in numerous commercials and voiceover campaigns for major brands, earning praise for her versatility and depth.
