Sappington resigned following a three and a half year stint with ADM21. A former Broadway choreographer, she will continue to choreograph freehand, and will continue her work with Valentina Kozlova's International Ballet Competition. Sappington's Broadway credits as choreographer include Doonesbury, Play Me a Country Song, Oh! Calcutta! and Where's Charley?, for which she was Tony-nominated. Like many choreographers she began as a dancer herself, and appeared in the original Broadway production of Promises, Promises as a member of the ensemble (one of the three main dancers in the legendary "Turkey Lurkey Time") and understudy to the female lead.

"I have enjoyed my time with ADM21 and remain firmly committed to the importance of preserving and presenting important choreography from Broadway shows and classic movie musicals," Sappington said in a press statement.

A new artistic director has not yet been announced. Nikki Feirt Atkins is currently the founder and producing artistic director. For more information visit ADM21.
