Christie Seaver began dancing with Edna Herzog and Anne and Nick Polajenko in Houston. She continued performing with Fort Worth Ballet under the direction of Nanette Glushak, Michel Rahn and later Paul Mejia, spending summers at Boston Ballet School and Pennsylvania Ballet School (as it was called then).
She later studied journalism at Boston University while also performing with choreographer Margot Parsons, then became dance critic for the Boston Herald. She has written about dance for publications including the New York Times, Dallas Morning News, Houston Chronicle and others. In 2004 Christie met her Irish husband when they both won New York Time/National Endowment for the Arts journalism fellowships. This led her to Dublin, Ireland, her current home. In Ireland she worked at Harmonia Publishing and for CARA in-flight magazine, as well as the Sunday Times. She is currently the ballet critic for The Irish Times.
Christie opened D4 Pilates in 2007 as a way to stay connected to her movement background. It was then she developed Ballet-lates®, a method that builds strength, confidence and belonging for people who have always wanted to dance. It is now trademarked in the US and 22 European countries and has an online platform with users on 3 continents. In 2022 she hosted her first Ballet-lates Urban Retreat in London.
