John McKissick, longtime football coach at Summerville High in South Carolina, has died at 95.
With a record of 621-155-13 as the football coach at Summerville, McKissick is the winningest coach at any level of the sport.
McKissick died on Thursday, November 28, at 10:45 a.m. ET of natural causes, according to Dorchester County Coroner Paul Brouthers.
He was in hospice care at home with his wife and daughter.
McKissick was head coach at Summerville from 1952 to 2014 before retiring in 2015. He won 10 South Carolina state championships with the school, with his last title coming in 1998.
He became the first coach to win 500 games in 2003, and he passed the 600-game mark in 2012.
"I had the opportunity to both play for and coach football with Coach McKissick," Summerville High athletic director Brion Rutherford told CNN. "Our prayers are with his family right now.
"Coach set a standard of excellence that was built around hard work, teamwork, and pride in school and community. Coach McKissick will be missed by our community; it's up to all of us to continue the legacy he set for Summerville High School and the Summerville community."
In his 63 seasons at Summerville, McKissick won a share of the region championship 37 times, according to CNN affiliate WCSC.
His teams went undefeated five times, and he only experienced two losing seasons during his entire 63-year tenure.
"He was an inspiration to everyone who had the opportunity to play for him," Summerville High School alumnus Chandler Ferrell told WCSC. "He did a lot for me and for Summerville High School and we are going to miss him like crazy."
