MacDonald spanned the entire gamut during his forty-five year association with high school athletics. His career began as a coach at Fowler High School in 1933. He moved into the Fresno school system in 1934. He was the line coach for Erwin Ginsburg at Fresno High School for several years and then became the athletic director and later became principal of Edison High School from 1946 until 1964.
