As a child, Kelly took dance lessons from Abby's for eleven years, then became of the first dancers at Abby Lee Dance Company until she quit to become a cheerleader.
On Dance Moms Kelly clashes with Abby for what she perceives as unfair treatment. Her daughters are often at the bottom of the ranking pyramid and Kelly blames Abby for not devoting more time to training them.
At the beginning of Season Three, Kelly pulled her daughters from the dance troupe to protest the perceived mistreatment. Later in the season, both kids returned.
