Yoast grew up in Florence, Alabama. After a three year tour in the United States Air Force, he attended Georgia Military College and later Mercer University, where he joined Sigma Nu fraternity and earned a Bachelor of Arts in Physical Education. He later earned a masters degree from Peabody College.
A high school and college athlete, Yoast turned to coaching as a career. He worked in Sparta, Georgia and Roswell, Georgia before moving to Alexandria, Virginia, where he spent several decades and earned his greatest notoriety.
Yoast's 1971 season at T. C. Williams High School served as the inspiration for Remember the Titans. Yoast, who is white, worked as an assistant to head coach Herman Boone, who is black, at the newly-integrated school. The team enjoyed a dominant season, winning the state title and taking a second-place national ranking.
Yoast had four daughters and seven grandchildren. He is now retired. He has published a book discussing his experiences in coaching, Remember This Titan.
