Arthur J. Gallagher & Co. has added environmental insurance brokerage expertise through the acquisition of Twin Elms LLC, a West Palm Beach, Florida-based firm specializing in environmental insurance products and services for US clients.
Twin Elms operates as a retail insurance broker focused on environmental insurance solutions. Its business centers on helping clients manage environmental risks and liabilities through insurance placement and risk management services. Its offerings include site pollution liability, contractor pollution liability, lender pollution liability, remediation cost cap coverage and insurance programs tied to storage tank exposures.
The acquisition brings a specialist environmental insurance operation into Gallagher's retail brokerage business.
Scott Houldin, Karl Touet and their team will remain in their current West Palm Beach location following the transaction. The business will operate under the direction of Bumpy Triche, head of Gallagher's Southeast retail property/casualty brokerage operations.
“Twin Elms is a highly regarded agency whose niche expertise will further enhance our environmental brokerage offerings. I am delighted to welcome Scott, Karl and their associates to Gallagher,” said J. Patrick Gallagher Jr., chairman and CEO of Arthur J. Gallagher & Co.
Twin Elms has specialized in environmental insurance since 1995 and works with clients and retail brokers throughout the United States on environmental risk transfer and liability management programs.
The deal adds to a series of acquisitions announced by Gallagher in recent weeks.
Recently, the company said its Risk Placement Services division had acquired McKee Risk Management, a Pennsylvania-based program administrator focused on construction, public entity and property business. Furthermore, Gallagher Bassett acquired London-based Mays Brown Solicitors, a law firm specializing in shipping and maritime legal services.
The transactions follow a period of continued acquisition activity across Gallagher's operations. In its first-quarter 2026 earnings report, the company reported completing eight acquisitions during the quarter, representing an estimated $49 million in annualized acquired revenue.
Gallagher's brokerage segment reported first-quarter revenue of $4.293 billion, compared with $3.314 billion in the prior-year period. The company reported total revenue before reimbursements of $4.716 billion for the quarter ended March 31, 2026.
Following the acquisition, Twin Elms will continue operating from its existing location while becoming part of Gallagher's global organization.
