It took a couple of days on this one, but we have received confirmation that, yes, Atit Shah has assumed the role of executive creative director at Digitas New York, effectively. Shah, who’s been with the agency for over 14 years, succeeds Matthew D’Ercole, himself a longtime Digitas vet who has moved on (we’re hearing possibly away from advertising and out of the continental U.S.). Anyhow, Shah has spent the last six years serving as SVP/group creative director at Digitas NY, leading creative for agency clients including of course, American Express, and working on new business efforts.
