Margaret is the oldest of the Ziegler girls, and that comes with responsibility. She always has to be perfect. Always training. Always working... It doesn't help that she has a constant, very forced, rivalry with her best friend, Brooke... Margaret has been dancing at the Aldc for nearly 10 years, and has always been Abby's ultimate favorite. This year, she has been cast on a show with her little sisters, Maddie and Mackenzie, and her mom. Here's her journey!
