He is the illustrator of "A Border Runs Through It: Journeys in Regional History and Folklore " by James "Big Jim" Griffith, "Arizona Politicians: The Noble and the Notorious " by Jim Johnson and "Two Arizona Black Birds" by Milton Lipson. Fitz is syndicated to more than 700 news publications, his award-winning cartoons have drawn both fire and praise.
Fitzsimmons also entertains audiences as a one-of-a-kind stand-up cartoonist and conference speaker. Known as the “Fastest draw west of the Potomac” Fitz has opened for PBS’ Mark Russell and has performed his “exceedingly silly” chalk talks in many conference meeting rooms, theaters, schools, and clubhouses. He has raised millions for Tucson’s charities for a quarter century by being the provocative, funny and entertaining master of ceremonies at thousands of charity events. For free. Any time as long as the cause is noble, the audience tomato-free and there are a few big names in attendance that he can besmirch, belittle, beguile and charm. He is Mr. Chicken Dinner with a black marker pen and a thick paper pad three by four feet perched on an easel.
His newest work is arranging, producing, and performing in the "Arroyo Café Radio Hour" a live radio show.
