Cliff Guffey is President of the American Postal Workers Union, which represents 220,000 employees in the clerk, maintenance and motor vehicle crafts.

He was Director of the union’s Clerk Division from 1999 to 2001, and Assistant Director of the Clerk Division from 1986 to 1999.

In his first foray into elective office in 1979, Guffey won the presidency of the Oklahoma City Area Local APWU. He served two terms before running for national office.
Prior to his work at the Postal Service, he served in the United States Marine Corps from 1968 to 1970 as a rifleman in the 2nd Battalion, 3rd Marine Division in Vietnam.
Guffey was born in Shawnee, OK. His father was a career pilot in the United States Navy and was stationed around the world. The family moved frequently, living in Hawaii, California, Alabama, and Naples, Italy, among other locations.
Guffey and his wife, Donna, have two daughters and four grandsons.
