The Grizzlies initially founded as the Seattle Jets in October 1998 and played their first competitive matches in 1999. In their debut season at USAFL Nationals, the club finished third.

Each year since then, the Grizzlies have been represented in the USA’s premier Australian Rules Football tournament, taking home a victory in the 2008 Division 2 Championships in Colorado Springs and falling one goal short of the Division 1 title the following year.

During the late 2000s, the team focused on player development and several local talents (including Ryan Kastl, Zach Johns and Kevin Stanley) blossomed into key members of the USA Revolution, who represent the nation in international competition. Recent Grizzly recruits Kiel Rasp and Max DePina also made the step up to play for the Revolution in 2015.

The Grizzlies’ Team of the Decade was named in October 2009, featuring key contributors like Kastl, Matthew Muller, Andrew Donlen and Greg Morton.

The Grizzlies maintain a strong presence in local, regional and national competitions and now compete regularly in the burgeoning Pacific Northwest League against clubs from Portland, Vancouver and Burnaby. We regularly play games at Greenlake Park and Mosier Park in Burien, with away trips in 2015 to Portland, Sacramento and Austin.
