Don Warren founded The Cavaliers in 1948 as the drum and bugle corps for Boy Scout Troop 111 in Chicago’s Logan Square neighborhood. Warren would go on to lead The Cavaliers and make his mark in the marching arts world, with more than 20 national championships and seven Drum Corps International world championships under his belt. Most importantly, he would help cultivate the next generation of leaders, educators and beyond.
