[1] The all-male Greenwood Boys Club Drum and Bugle Corps was founded in 1957 by Jack Avery in Seattle’s Green Lake area.
After witnessing the 1963 VFW Junior National Championship in Seattle, the Thunderbirds' leadership decided to put the corps on the competition field.
In 1966, Rod Stubbs left the Thunderbird organization, and with some of its marching members, started a new corps, named the Cascade Cadets.
Although they had some competitive success in its early days, some years the organization struggled to put a corps on the field.
In 2002, the Seattle Cascades moved into Division I (now World Class) competition and became the first corps from the Pacific Northwest to earn a place in Finals.
