Jay Fleck drew a lot as a child but grew up to pursue other things, such as a degree in computer engineering. He found a renewed interest in art while living in Chicago, inspired by the art and culture found throughout the city. Jay is the author-illustrator of Tilly & Tank and the illustrator of a number of other children's books. He now resides in a suburb south of Chicago with his wife, two children, and loyal dog, Otis. He spends his spare time running, reading, and daydreaming.
