Clemenger BBDO CTO Mark Gretton exits amid agency restructure

Clemenger BBDO’s chief technology officer Mark Gretton has become the latest executive to leave the agency, as parent company Omnicom Group prepares to finalise its global acquisition of IPG Mediabrands.

Gretton steps away from Clemenger nearly a decade after joining its CHE Proximity division in September 2016 as director of its digital consulting practice.

Three years later, he was appointed CHE Proximity’s first chief technology officer, overseeing the agency’s technology strategy and development through its rebrand to Chep Network and its integration into Clemenger earlier this year.
