Elizabeth joined McMillen in 2009 after having worked at Sotheby's, where she was a specialist in the Old Master paintings department. Elizabeth was brought to McMillen to make the firm more accessible to younger clients and to clients who have never before used a full service interior design firm. Elizabeth has worked in Chicago, Richmond, New York City, and eastern Long Island. Her projects have been published in House and Garden, The New York Times, and Traditional Home. In February 2015, House Beautiful named her as one of their "Next Wave" designers, and a pied-a-terre that she decorated was featured in the July/August 2015 issue of House Beautiful.
