Publicis Groupe ad agency Fallon has appointed Nikki Baker as its new CEO. Baker, who joined the agency in 2018 and has served as Co-Chief Creative Officer with Leslie Shaffer since 2021, succeeds Rocky Novak, who has been in the role since 2019 and who is leaving the agency to pursue a new opportunity. He'll be staying on until mid-January to help with the transition.  

Baker’s recent credits include taking the creative lead on the Walmart business as part of a Publicis Groupe team and spearheading campaigns such as the award-winning "RomCommerce" 23-episodic series and the Mean Girls campaign, among many other efforts. Baker will continue to be involved in the Walmart business through the Publicis Power of One model.  

Together with Shaffer, Baker has also been instrumental in elevating Fallon's creative output for long-standing clients like Arby's, Mattress Firm, and Front Door/American Home Shield.  

Baker previously held positions as creative director and art director at agencies including DDB and GSD&M, working with major brands such as McDonald's, Southwest Airlines, and Wrigley. Her work has been recognized by Cannes Lions, Clio Awards, and One Show, among others.
