What Kelley Drye & Warren does

Kelley Drye & Warren LLP is an Am Law 200 full-service law firm headquartered in New York, founded in 1836 and operating through nine U.S. offices. The firm delivers legal services across 13 practice areas—Advertising and Marketing, Antitrust, Bankruptcy and Restructuring, Corporate and Tax, Employment and Employee Benefits, Environmental, Government Relations and Public Policy, Intellectual Property, International Trade, Litigation, Privacy and Information Security, Real Estate, and State Attorneys General—serving Fortune 500 corporations, government entities, and middle-market businesses. The firm is recognized in Chambers USA 2026 across 13 practice areas with 25+ attorneys ranked and 63 attorneys in Best Lawyers in America 2026. Notable case outcomes include a record $2 billion PFAS-related environmental settlement for New Jersey against DuPont, representation of more than 75 creditors committees over the past decade, and 400+ retail bankruptcy case representations.

The firm's business model is relationship-driven professional services, with revenue generated through hourly billing (partner rates reported at $300/hour and associate rates at $250/hour in environmental litigation) complemented by alternative fee arrangements, fixed fees, and retainers. Client acquisition is partner-led via lateral hires with portable books of business, referrals, industry reputation, and thought leadership through the firm's Viewpoints platform, specialized blogs, podcasts, webinars, and conference speaking. The firm operates as a private limited liability partnership owned and managed by its partners, with no external institutional ownership. Practice groups are led by partners with prior government experience—former DOJ Antitrust Division leaders, senior federal prosecutors, and former State AG staff—enhancing regulatory access.

Distribution occurs exclusively through direct attorney-client engagement at the firm's nine offices (New York HQ, Washington DC, Chicago, Houston, Los Angeles, San Francisco, San Diego, New Jersey, Stamford), with the firm's Georgetown Economic Services subsidiary providing integrated economic analysis for antitrust matters. The firm has been actively expanding through lateral partner hires of former government officials and office growth, including a new San Francisco office opened in March 2026 and a relocated San Diego office in Del Mar in June 2026.
