Greg Foley didn't know what he wanted to be when he grew up. So he never really grew up. Just like Dex, he's always wanted to be the World's Best Great Ever at something. So he tries his best at being lots of different things like author, illustrator, designer, director, cartoonist, New Yorker cover artist, teacher, inventor, and dad.

Along the way Greg has received numerous honors including the Charlotte Zolotow Award, Art Directors Club Gold and Silver Awards, a Grammy nomination, a Guinness World Record, and his work has been exhibited at places like the MoMa, Centre Pompidou, New York Public Library, Yale's Beinecke Library, and many more. Greg lives in Austin, Texas, with his family.
