The adidas Portland Timbers Alliance is a strategic partnership with elite local youth clubs in the Portland Timbers' development territory, designed to build unique working relationships and development opportunities to help channel the top youth players towards the Timbers' development programs and the Timbers Academy. Eastside is proud to represent the Timbers Alliance as a founding member and a continuing flagship club.

As part of the alliance, the Timbers share coaching resources and curriculum with Alliance clubs in the development of both boys and girls youth players. Additionally, youth clubs in the Alliance will be allowed the unique privilege of incorporating the Timbers brand into their club name and wear a special adidas Timbers Alliance badge as part of the uniform. On the field, each alliance club will wear the same jerseys in recognition of the partnership with the Timbers.

Youth players from across the Timbers development territory, not just affiliated with an adidas Timbers Alliance club, all have the opportunity to try out for a Timbers Academy team or Thorns FC Academy team or a place in one of the Regional Training Centers throughout the state as well as the Olympic Development Program. Additionally, the Alliance clubs regularly hold special tryouts for one-off Alliance teams for larger showcase events and tournaments. Eastside regularly places players in each of these programs and we're proud to continue developing top-class players at every age group. Alliance clubs also hold special "play day" events for younger players to provide additional game and development opportunities.

Other Alliance Clubs: Washington Timbers, Westside Timbers, Bend FC Timbers, Rogue Valley Timbers, Eugene Timbers, Capital FC Timbers, Boise Nationals Timbers and Sting Timbers FC.
