His departure, effective immediately, is the culmination of a desire by the company's parent Maxxcom to drive the agency forward, according to an Interfocus statement this week. It follows a substantial restructuring in which the agency has hired a number of key executives.
Hooper led Interfocus' 2001 buy-out from the Lowe Group after which it sold a 60 per cent stake to Maxxcom, a Canadian-listed holding company.
Following the Maxxcom deal, Interfocus declared its intention to expand further through acquisitions in advertising, direct marketing, new media and design. The sale enabled Interfocus to acquire Osprey London from Osprey Communications.
Hooper has played a role in industry affairs as the president of the MCCA and of the new Communications Agencies Federation.
Interfocus is launching a "living media" branch called Involve. The Royal Opera House and Energy Saving Trust will be its first clients.
Fergus Ross, who will head the division, said: "Living media, which is face-to-face or word-of-mouth, is a growth area and a highly influential one where messages cut through to drive sales."
