Bonnie Beck (born 1980), known as Bonnie D.Stroir, is a roller derby coach and skater. D.Stroir began skating in October 2003, after reading an article on the sport in Jane magazine. She had been working as a barber in Oceanside, California, considered moving to Austin, Texas, to learn the sport from TXRD Lonestar Rollergirls. Instead, she stayed in San Diego and joined the new Los Angeles Derby Dolls league, commuting to each practice. Citing her love of the game, she returned to practice in 2012, skated with the San Diego Derby Dolls in 2013, and retired for a second time in September 2013.
