Jennifer Barbee joined the LA Derby Dolls in October 2003, rechristened herself Kasey Bomber, and became the co-captain of the fun-loving Trust Fund Terrors. Since roller derby was still the early days of its revival, Jennifer made it her mission to unite the Dolls in spirit with all the other leagues across the country. Many airline miles, toasts to success, and skating-induced blisters later, she took that mission one step further by helping to organize the first national roller derby convention, Rollercon, in Las Vegas in 2005. After several exciting seasons, Jennifer retired from team skating in 2008 to focus on coaching, and refocus on writing for publications such as Blood and Thunder Magazine. In 2009, she was hired to help train actresses Ellen Page, Juliette Lewis, and Drew Barrymore for the derby-inspired film Whip It! Her co-trainer, and good friend was Alex "Axles of Evil" Cohen. The seeds of Down & Derby: An Insider's Guide to Roller Derby were planted during the many hours of down time on the film's set in Michigan, and the friends became writing partners.
