The New Orleans-based law firms of Gordon, Arata, McCollam, Duplantis & Eagan LLC and Montgomery Barnett LLP will merge next month to become Gordon, Arata, Montgomery, Barnett, McCollam, Duplantis & Eagan LLC.

The deal will be effective March 1. The merged firm will have offices in New Orleans, Baton Rouge, Lafayette and Houston.

Gordon Arata was founded in 1970 as an oil and gas law firm, while Montgomery Barnett, founded in 1892, has focused on admiralty, maritime and business law.

"We are excited to merge with Montgomery Barnett’s group of distinguished lawyers," said Tim Eagan, managing member of Gordon Arata. "This merger will expand the existing services of both firms and provide additional resources to handle matters for clients across diverse industries."
