Kelly Collier has been drawing since she was little and studied illustration in college. She is the author-illustrator of A Horse Named Steve and Team Steve, and the illustrator of Sloth and Squirrel in a Pickle and the Izzy series. She has an identical twin sister and an older brother. The idea for A Horse Named Steve came from a doodle she did to fill a small empty frame at home. Kelly lives in Toronto, Ontario, with her husband and daughter.
