A founding member of Chicago's legendary St. Nicholas Theatre Company (with Pulitzer Prize-winning playwright David Mamet and actors William H. Macy and Stephen Schachter), Cox was among the city's first performing arts marketing, development and management leaders to emerge under the late, great Lyric Opera impresario Danny Newman. She has since worked with and consulted for a wide range of not-for-profit arts organizations in Chicago and across the country. Cox has served as the Executive Director of the Chicago Alliance for the Performing Arts and was the Director of Marketing for Manhattan Theatre Club and the Boston Ballet. As a consultant, she has worked for the National Endowment for the Arts, the City of Boston, the Atlantic Theatre Company (founded by Mamet, Macy, Felicity Huffman and others), The National Jewish Theatre, City Lit and regional foundations such as the Chicago Community Trust and the Cleveland Foundation. In addition to her work in the arts, she is a member of the Women's Board of the Rehabilitation Institute of Chicago, and sits on the Board of Directors of High Jump, an academic enrichment program for talented, economically challenged middle school students. She taught Arts Marketing for Columbia College, and has lectured on marketing and development in the arts at Columbia University, New York University and Adelphi University. In addition to the cultural arena, Cox's work in the not-for-profit sector extends to urban education, environmental concerns and poverty issues on a local and national level-including work with the Global Fund for Children and CARE's Women's Initiative.
