Victor, Marsh’s global managing general underwriting business, has appointed Charles Williamson (pictured left) as its CEO, succeeding Brian Hanuschak (pictured right), who will become the company’s chairman.

The appointments will go into effect on August 1.

As CEO, Williamson will lead operations for all of Victor's businesses in the US, Canada, UK, Netherlands, Italy, Germany and Australia, delivering solutions to insurance brokers and their customers. He will report to Martin South, president and CEO of Marsh.

New York-based Williamson brings three decades of underwriting experience to Victor, including serving nearly 25 years in various executive roles at AIG. Most recently, he served as co-founder and CEO of Vault, a managing general agency and reciprocal insurance exchange serving a high-net-worth clientele.

“I look forward to leading Victor’s exceptional global team as we continue to build industry-leading underwriting programs and insurance solutions for our distribution partners,” Williamson said.

“Charles is an outstanding leader with deep underwriting, distribution, and product development expertise,” South said.

“Under his leadership, Victor will be well-positioned to support carriers and agents around the world with cutting-edge digital distribution and underwriting platforms.”

Hanuschak will continue to operate in Chevy Chase, Maryland, becoming a strategic advisor to Victor’s leadership team, working closely with Williamson to ensure a smooth transition for both colleagues and clients.

“I would also like to recognize Brian for his exceptional contribution in leading Victor and thank him for his continued support,” South added.
