Liskow & Lewis

What Liskow & Lewis does

Liskow & Lewis, APLC is a New Orleans-headquartered, full-service law firm founded in 1935 that specializes in energy, maritime, environmental, and complex commercial matters across the Gulf Coast region. The firm employs approximately 250 people, including 142 listed attorneys, and operates from five offices (New Orleans, Baton Rouge, Lafayette, Houston, and New York City). Its core practice areas span Energy (litigation, regulatory, transactional, and energy transition), Maritime (casualty response, litigation, transactions, Jones Act, OCSLA, LHWCA, DOHSA), Environmental (compliance, enforcement defense, litigation), Commercial Litigation, Corporate/M&A, Real Estate, and Labor & Employment.

The firm generates revenue exclusively through professional services fees billed to clients for regulatory advice, transactional counsel, and high-stakes litigation. Its customer base spans regional and national energy companies, vessel owners and operators, maritime insurers, environmental-sector clients, and government entities, with marquee engagements including representation of the State of Maryland in the Francis Scott Key Bridge allision settlement (the largest single maritime property damage settlement in U.S. history), Exxon Mobil in vicarious liability matters, and lead roles on major offshore incidents such as DEEPWATER HORIZON, GOLDEN RAY, and SEACOR POWER. Client acquisition is driven by industry reputation, professional networks, and referrals rather than field sales.

Underlying technology is limited to standard law-firm infrastructure; the firm is not a technology company and has no proprietary AI/ML products, though it does offer integrated eDiscovery services within its litigation practice. The firm maintains multiple thought-leadership channels (Energy Law Blog, Gulf Coast Business Law Blog, Maritime Law Blog, Energy Law This Week Podcast, Louisiana Industrial Insights Hub), is a member of the Meritas global alliance of independent law firms, and is recognized in Chambers USA 2025 (32 attorneys, 10 practice areas) and Best Lawyers in America 2026 (107 attorneys). Ownership is structured as a Louisiana professional corporation, with equity held by shareholder attorneys and no disclosed parent company or institutional investor.
