He first earned notoriety in his multi-platinum punk rock band Headstones, when he caught the attention of filmmaker Bruce McDonald, who cast him in the lead of cult-classic film Hard Core Logo, distributed through Quentin Tarantino’s Rolling Thunder. 

Dillon's ability to capture honest and realistic portrayals of complicated characters has been his calling card. From his breakout role in Flashpoint, through which he earned the top industry achievement of a CSA award for Best Performance by an Actor in a Continuing Leading Dramatic Role, to The Killing, Twin Peaks, and Wind River with Academy Award-nominated director Taylor Sheridan. Teaming up again with Sheridan, he has appeared alongside Kevin Costner for the critically acclaimed, SAG Awards-nominated series Yellowstone.

Dillon is also well-known in the voice world. Currently the voice of Chevy, Dillon has represented many multi-national brands, including Hyundai, the video game Left4Dead, and Manulife.

Following a celebrated return to the stage with the Headstones, Dillon has since been back in the studio recording new music. ‘LITTLE ARMY’ includes the #1 hit single 'Devil's On Fire', and 'PEOPLESKILLS', with lead single 'Leave It All Behind' hit number 3 on the Billboard Rock Charts. Headstones are currently back in the studio working on their new album ‘FLIGHT RISK’.
