Marty O'Halloran, former global chairman of DDB Worldwide, has joined Thrive PR and Communications AU/NZ in an advisory role. 

Spanning a career of nearly four decades, O'Halloran went from account manager in Melbourne, Australia, to global CEO and later global chairman of DDB Worldwide. 

"Marty has led one of the most awarded creative networks in the world and there are few leaders globally who are held in such high esteem," Thrive CEO and founder Leilani Abels said. 

O'Halloran said he was drawn to Thrive's entrepreneurial spirit, its earned-first philosophy and the agency's commitment to developing talent. 

"Thrive has built something special — a modern communications agency with strong values, ambitious leadership and a clear belief in the power of creativity and earned influence," O'Halloran said.
