Trusted lawyers with a track record of resolving difficult legal problems.


Thomas and Harold Flanagan have over twenty-five years of experience successfully litigating complex cases and negotiating high-stakes deals. Together, they have assembled a team of attorneys who are distinguished by their academic excellence and who have flourished under the firm’s leadership and guidance. U.S. News – Best Lawyers has given Flanagan Partners a Tier 1 ranking, and Super Lawyers named the firm the top small litigation firm in Louisiana. And our lawyers have been recognized by Best Lawyers, Chambers USA, Louisiana Super Lawyers, and Benchmark Litigation as leaders in their fields. Clients routinely entrust us with high-profile, “bet-the-company” matters against older and larger firms, and we are proud of our record of success. We owe that success to the caliber of our attorneys and their ability to tackle complex problems.

They are comfortable navigating each case through the appellate process, and they are routinely retained by litigants post-trial to challenge or defend significant judgments on appeal.
