The big gyms in NW Washington (not sure if you're going to be near Seattle or up towards Bellingham/ near Canada) are;
South Elite (Covington) Levels 1-5 (Mini 1, Senior 1 and 2, Junior 3, Senior 4, Senior 5, IOC 5)
Connect Allstars (Bellevue) not quite sure but ( Youth 1, Senior 2, Junior 3, Senior 3 Senior 4, Senior 5)
Natural Venom Allstar (Fife) (mini 1, Junior 2, Senior 2, senior 3, senior 4, Senior 5)
Natrual Venom has an AMAZING coed 4 team, and their level 5 team is new, but getting really great!
South Elite is amazing. I'm sure you've heard of Diamonds, so no needed explanation. All their teams are pretty fierce
Connect is also amazing. I love their Sm Senior 5 team!
I don't think there are any R5 teams in Washington at the moment.
Hope you enjoy WA!
