Mad Rollin' Dolls is a flat-track derby league in Madison, Wisconsin, owned and run by the Dolls. Flat-track derby is a hard-core sport played by independent, strong, modern women.

Mad Rollin' Dolls provides an outlet for female aggression and self-expression. We entertain and inspire both on and off the rink; we encourage and organize women to participate in service to the community; we get fit, have fun and throw killer parties.
