Best Law Firms in Louisiana for Mass Tort Litigation / Class Actions - Defendants

Fishman Haygood is a Louisiana-based litigation and transactional firm built for the matters that require it most — complex disputes, high-stakes transactions, and the intersection of both. With 40-plus attorneys in New Orleans and Baton Rouge, the firm runs lean by design: direct partner involvement, precise judgment, and three decades of earning the trust of clients who need it done right.

We handle everything from commercial disputes, securities litigation, class actions, environmental, energy, and bankruptcy matters to M&A, real estate, and private equity deals for businesses, institutions, and individuals nationwide. Attorneys routinely try high-stakes cases to verdict, lead complicated chapter 11 restructurings, and close complex transactions. As a boutique firm, we're not smaller for the sake of scale, but intentionally structured to handle sophisticated, consequential work.
