A marketing thought leader, Margaret has held previous leadership roles at Gerson Lehrman Group, Siebel Systems, and Eir; has published in Forbes, Harvard Business Review, and elsewhere; and is recognized as one the most influential CMOs on Twitter.

She is also an influential advocate for Irish design, launching the #WearingIrish initiative this year, 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 sits on the board of the Origin Theatre.
