June 25 - (The Insurer) - Christopher Spiridis has joined Marsh as US project risk leader from Aon, where he was most recently national project solutions leader for the broker’s construction business.
According to sources with knowledge of the situation, he will report to Jim Dunn, who made the move from Aon to Marsh early last month as US construction practice leader.
He will be responsible for supporting the growth and development of Marsh’s construction practice, they added.
A Marsh spokesperson confirmed the Spiridis appointment.
As previously reported, Dunn’s arrival – which was confirmed at Riskworld 2025 in Chicago – was effectively a replacement for Rob McDonough after he left to join Aon earlier this year. His exit was followed by Marsh launching a legal action against its rival over the hire of a team of 20 in the construction surety space.
Dunn reports to Michael Pellegrini, U.S. and Canada specialty leader for the broker.
