After spending barely six months at Arnold Worldwide as VP, creative director, Tim Allen has moved on and assumed the newly created position of creative director, experience design at SapientNitro’s Boston office. In his new role, Allen will oversee “navigation, organization and interaction design” across web, mobile and digital.

The creative is perhaps best known for his three-year stint at R/GA, where he helped redesign the agency’s much-lauded Nike+ platform. Now at SapientNitro’s Boston branch, which has worked with clients including Dunkin Donuts and Ram, Allen will join an agency that counts over 100 creatives on its roster.
