Founded in 2006, the team most recently played in USL League Two, the fourth tier of the American Soccer Pyramid.

The Tacoma team was introduced into the league at very short notice in 2006, when it was announced that the now-defunct Spokane Shadow franchise was suspending operations for the season.

O'Brien was replaced as head coach by former Rochester Rhinos and Seattle Sounders midfielder Greg Howes in 2009, and the change in leadership, combined with the excellence of the expansion teams in the Northwest, seemed to affect Tacoma on the field.

Rory Agu was again Tacoma's top scorer, hitting the net 11 times, while Leighton O'Brien provided 4 assists.

2010 began with a change in coaching with former Canadian national team player Gerry Gray replacing Greg Howes.
