McGrath was born in Hollywood and raised in Echo Park and Altadena, California. At the age of 13 she was sent to a Fundamentalist Baptist correctional institution called the Victory Christian Academy, and credits that for much of the inspiration for her artwork. She later attended Pasadena City College.

McGrath began her career in art by making flyers for her punk band Tongue and creating a fanzine called Censor This, a collective effort with several other artists. Her first showing was at La Luz de Jesus Gallery in Hollywood. She currently shows at their new gallery, Billy Shire Fine Arts in Culver City, California.
