After graduating from college, Grimes fulfilled his youthful dream of coaching at his alma mater. He went on to spend a long career serving his home county as a teacher, coach, principal, and administrator.
He helped many athletes pursue successful careers after high school. Even after retiring more than 20 years ago, he remained a dedicated supporter of Marion County athletics and rarely missed a game, regardless of the sport.
Grimes was inducted into the TSSAA Hall of Fame and the Greater Chattanooga Sports Hall of Fame. He was 79. A celebration of his life will be held Sunday, November 1, at the Jasper chapel of Rogers Funeral Home.
