Nancy Vonk/Janet Kestin, co-CCOs, Ogilvy & Mather, Toronto

Award-winning creative team Nancy Vonk and Janet Kestin were practically iconic in Canada, sporting the tag-team name Jancy. Then came Dove. Their highly successful Canadian contribution to the global campaign is now a case at Harvard's Business School and the creative is part of the permanent collection at the Royal Ontario Museum.

They first paired up in 1991, but before meeting shared similar paths, with stints at agencies such as Y&R and Leo Burnett. Today, they lead Ogilvy's creative department. In 2005, they published a book: Pick Me: Breaking into Advertising and Staying There, based on their online column on ihaveanidea.org column, proving an ongoing passion for mentoring.
