Chief Marketing Officer

Margaret Molloy, from Offaly, is the global chief marketing officer at Siegel+Gale, the strategic branding consultancy. A marketing thought leader, Margaret has held previous leadership roles at Gerson Lehrman Group, Siebel Systems, and Eircom; has published in Forbes, Harvard Business Review, and elsewhere; and is recognized as one the most influential CMOs on Twitter.

She is an influential advocate for Irish design as well. In March 2016 she launched the #WearingIrish initiative, encouraging everyone to wear Irish fashion once in March and to post their pictures on social media. For her part, she donned fashion and accessories by Irish designers every day in March. Her vision is for #WearingIrish to be an annual movement. She also serves on the advisory board of the New York Irish Center and is a supporter of Origin Theatre.

Margaret earned her M.B.A. from Harvard Business School and her undergraduate degree from the University of Ulster and La Universidad de Valladolid, Spain. Growing up the eldest of six children on a farm, Margaret credits her accomplishments to her parents’ work ethic and thirst for education.

She lives in Manhattan with her husband, Jim O’Sullivan, chief U.S. economist at High Frequency Economic, and their sons, Finn and Emmet.
