After finishing her illustration undergrad at Brigham Young University, she spent several years at a crafting company called Provo Craft, working as a cartridge content designer for their Cricut die-cutting machine. Her favorite part was working on licensed material, getting to play with vector art from Disney, Sanrio, Sesame Street, Nickelodeon, and Warner Bros. She even got to visit the Warner Bros HQ in Burbank and meet some of their licensing execs. If you pick up the Superman Cricut cartridge, you'll find the font included is her handwriting! (like in the below example that someone posted online)
