In 1942, and from 1946 to 1948, he played college football for Murray State, and was left guard for their 1948 conference championship team.^[1] He missed seasons between 1943 and 1945 due to serving in the United States Army in World War II.^[2]

After graduating college with a bachelor's and master's degree, Cullivan started a coaching career, being named assistant at Fulton High School in Kentucky in 1949.^[3][4] After two years there, he returned to his alma mater Murray State as an assistant coach.^[5] When head coach Fred Faurot resigned in 1956, Cullivan was named the replacement.^[6] He finished his first season as head with a 6–4 record, with three of the four losses coming by one point.^[7]

His team compiled a 3–5–1 record in 1957, a 3–7 record in 1958, and a winless 0–10 in the following, leading to his firing in January 1960.^[8][9]

After leaving Murray State, Cullivan took a year off from coaching to work on a doctorate from University of Indiana.^[10] In 1961, he was hired by Eastern State College (now Eastern Kentucky University) as defensive coordinator.^[11] He resigned in 1964 to join Appalachian State University.

He retired after 1970, and sat out the next two years. He returned in 1973 as coach of North Stanley High School in North Carolina, saying, "I sat out (of coaching) two years, but I got restless. Raising cattle didn't work out."^[10] He left after five years, returning to college coaching with the Guilford Quakers as defensive line coach in 1978. He moved back to the high school level in 1979, joining Cawood High School in Kentucky as an assistant.^[14] He was promoted to head coach in 1980, and posted a 65–21 football record in nine seasons.
