“In his role as chairman for the balance of this year, we’ll look to Matt to continue providing a broad strategic vision for the group, which is something that’s made us a leader in digital and data-enabled marketing,” commented Michael Roth, chairman and CEO of Interpublic.
Roth credited Tajer with turning Australia into a "growth engine" for the network by creating a collaborative work environment which encourages new capabilities to come to the fore. “Henry is a great media executive, who is valued by our people, clients and media partners."
