Abigale “Abby” Lee Miller (born September 21, 1966) is an American dance instructor, choreographer, and the director and owner of Reign Dance Productions. She was also the founder of the Abby Lee Dance Company and appeared on the reality television series Dance Moms for seven seasons. In June 2016, she pleaded guilty to felony bankruptcy fraud and was sentenced in May 2017 to one year and a day in federal prison.
Miller was born on September 21, 1966, in Pittsburgh, Pennsylvania, to Maryen Lorrain, a dance teacher, and George L. Miller.
Miller grew up around dance in Penn Hills, Pennsylvania, a Pittsburgh suburb, studying under her mother's direction at the Maryen Lorrain Dance Studio. Miller eventually took over the studio in 1995 and renamed it Reign Dance Productions. She became certified by Dance Masters of America and became a member of Dance Masters of Pennsylvania Chapter #10 in 1986, but her membership was terminated in February 2012, with DMA saying Miller's reality-TV show Dance Moms was "a total misrepresentation of our dance educators and their students and is detrimental to the dance profession."
