Bowers began his career in advertising and editorial illustration, working with clients including Proctor & Gamble, Wendy's, Owens-Corning and the Cincinnati Enquirer. He was recruited by Hallmark Cards and worked five years at their headquarters in Kansas City, Missouri as a greeting card artist and as an original member of the company's humor group, Shoebox Greetings.
Bowers' first children's book illustrations were published in 1986. Since then, he has illustrated over 50 additional titles, including The New York Times bestsellers: Dream Big, Little Pig! written by Kristi Yamaguchi and Dinosaur Pet by Neil Sedaka and Marc Sedaka.
His children's book illustrations have received numerous state and national awards and recognitions. Several of his paintings have been included in Society of Illustrators (NY and LA) and Spectrum exhibitions.
