Insurance broker and risk advisor Marsh, a subsidiary of New York City-based professional services company Marsh & McLennan Cos. Inc., announced Thursday that it has appointed Martin South as president of its U.S. and Canadian division, effective Sept. 1.

South will report to John Doyle, president of Marsh, and will be based in Marsh’s New York City office. South will oversee Marsh’s U.S. core brokerage, businesses in Canada, and portfolio of U.S. businesses.

Most recently, South was CEO of Marsh’s Asia-Pacific region, beginning in 2013. Rob Bentley, former president of the U.S. and Canada division, is moving on to work on strategic initiatives across Marsh & McLennan's risk and insurance services segment, which includes Marsh and subsidiary Guy Carpenter.

South has 30 years of global operating experience in several insurance industry positions. He previously served as CEO of Marsh Europe, and prior to that, CEO of Marsh U.K. & Ireland. At Zurich Financial Services, South was a member of its group management board, responsible for all of Zurich’s operations outside North America and Europe.

“Martin is a highly accomplished and talented executive who’s consistently produced results in important Marsh leadership roles around the world,” said Peter Zaffino, CEO of Marsh, and chairman of Marsh & McLennan’s risk and insurance services segment.
