Greg Walsh, who joined Havas Media Group two years ago from Interpublic, has been named CEO of North America, filling a role that has been vacant since Colin Kinsella departed in January.
Walsh, who joined HMG as Global Chief Commercial Officer, was given the additional role of COO in February, a position which he retains.
Walsh, who reports to Global CEO Peter Mears, was previously global president of Interpublic barter media unit Orion Worldwide, and prior to that had a long run as a financial executive at IPG Mediabrands.
