Private insurance broker Lockton has announced the appointment of Brett Gillmon as U.S. Property Practice Leader, an Atlanta-based role.

Gillmon will leverage his three decades of industry experience to oversee the strategic direction and continued growth of Lockton’s property offerings across the U.S.

He will report to Devin Beresheim, Lockton’s U.S. Risk Solutions Leader, who commented: “Brett is exceptionally well suited for this role. He is an immensely respected leader in the property market, and a highly regarded technical and strategic partner to our Associates and clients. I know he will do an outstanding job helping shape the next iteration of Lockton’s U.S. Property Practice.”

Gillmon joined Lockton in 2017 as the Property Practice Leader for the Southeast region, supporting offices in Atlanta, Birmingham, Charlotte, Miami, Pembroke Pines, and Tampa.

In that position, he oversaw the strategic placement and servicing of property and construction risks for some of Lockton’s most complex property accounts nationwide.

Prior to Lockton, the executive served a 20-year tenure at Marsh, most recently as Managing Director in its U.S. Property Practice.

Throughout his career, he has focused primarily on global property and builders’ risk, supporting major U.S.-based clients and holding positions in Dubai, London, New York, and Atlanta.
