Greg Hahn is Co-founder and Chief Creative Officer of Mischief@No Fixed Address. 
Prior to Mischief, Greg was CCO of BBDO New York for nearly 15 years, where he became one of the most awarded creatives in the world (Cannes Grand Prix, Emmys, all that), and helped BBDO become one of the most awarded companies in the world. Yet in Spring of 2020, Greg headlined a wave of high profile layoffs at BBDO in reaction to pandemic fears.

Just two short months later, Greg co-founded Mischief. Just two short years later, Mischief was named Agency of the Year by Adage, Agency of the Year by Campaign US, and the second most innovative agency by Fast Company. Marking one of the most all-time legendary starts by any creative agency ever.
