The Rose City Rollers are based in Portland, OR and are the largest roller derby league in the world! Established in 2004, the league has grown to 17 different teams & programs with skaters ranging in age from 7 to 60 years old. It has over 400 smart, tough, accomplished women, girls and gender expansive individuals who skate fast, hit hard, and defy stereotypes about athletes in women's sports. They are an almost entirely volunteer-run 501c3 non-profit organization.
