Tom attended Bear Grove No. 5 Country Day School and Guthrie Center High School before relocating with his family to Greeley, Colorado. After graduating from Greeley Central High School in 1962, he enlisted in the United States Air Force. During his service, he was stationed primarily at Warner Robins Air Force Base in Georgia, where he worked as a B-52 bomber mechanic until his honorable discharge in 1966.
