In 2012, he became the first American football coach in history (high school, college or professional) to win 600 career games. His 600th win came against Summerville's Ashley Ridge High School. As of 2013, he hasn't missed a game in 62 years and is the longest serving high school football coach of all time. He has led Summerville to 10 state championships. With 601 wins, McKissick holds the record for most wins by a football coach at any level. He graduated from Kingstree High School in Kingstree, South Carolina, then went to Presbyterian College for two years before being drafted into the army (as a paratrooper). He returned to Presbyterian to graduate with a degree in economics in 1951. He then worked for his father for a while before finally getting the coaching job at Summerville High.
He has coached all three of his grandsons, Richard and Joe Call, and Donny McElveen. He was elected to the National High School Hall of Fame in 1990.
