At the time of its opening, CEO Chris Slatt claimed it was "the largest synthetic-turf soccer complex in the U.S."[1] From 2008 to 2024, Seattle Sounders FC of Major League Soccer has had offices and training facilities at the complex, whose main stadium hosted the Sounders' second-division incarnation in 2008 and has since staged the team's Lamar Hunt U.S. Open Cup matches.

[9] That offer sparked the formation of Starfire Sports by Slatt, Steve Beck, and Mark Bickham, who negotiated a 40-year lease with Tukwila to allow them to build and operate the complex.

Beginning in summer 2004, English Premier League powerhouse Manchester United offered training at Starfire as part of their Soccer Schools program.

[13] An expansion was unanimously approved by city leaders in a public hearing at the beginning of 2008 for the offices and training facilities of Seattle Sounders FC.

In 2004, the stadium field became only the eighth American artificial-surface pitch to earn "recommended" status by FIFA and was thereby sanctioned for international play.

The expansion undertaken by the complex in 2008 also included new fields along with a workout and fitness area for the Sounders FC, as well as offices for the coaching and technical staff.
