Specialty lines insurer Valiant Insurance Group is expanding its New York City headquarters by moving into a space it says will allow it to double its workforce.

The move to 110 William St. is expected to provide the company enough space for up to the three years, the company said in a statement.

“Despite challenging economic conditions, we’ve enjoyed several years of great success building out our U.S. organization,” said Gary Dubois, president and CEO of Valiant, in a statement. “As a result, this move to larger space will allow us to further develop the resources and personnel to continue effectively serving our agents, brokers and client policyholders.”

Valiant Insurance Group, Inc. provides specialty property and casualty insurance products and services to the U.S. agency and brokerage market through its main operating subsidiaries Valiant Insurance Co. and Valiant Specialty Insurance Co.
