After leaving Warrior, Ryan is now a prominent figure and representative for Brine Lacrosse. Still living in Oregon, Powell's entire income comes solely from lacrosse. Ryan lives with his fiancé Marlee and still is being an innovator of the game through education as opposed to playing, whether it is from the NLL, the MLL, or from the Powell Brother's Lacrosse Camps.
