Cozen O'Connor

Cozen O'Connor is a full-service law firm founded in Philadelphia in 1970 as a four-lawyer practice by two litigators with complementary strengths. More than five decades later, it fields more than 1,000 attorneys across 35 offices in North America and Europe and ranks among the Am Law 100.

The firm's work spans litigation, subrogation and recovery, corporate transactional law, and insurance law, with particular strength in insurance, corporate transactions and M&A, sports, and government and public policy. Alongside its legal practice, it runs ancillary businesses launched in response to client demand: Cozen O'Connor Public Strategies, which provides public policy and government strategies services; COSECURE; and CODISCOVR, its legal technology and eDiscovery offering.

The firm describes its culture as rooted in tenacity, intellectual rigor, and a willingness to challenge the establishment, with a tradition of calculated risk-taking and strategic expansion. Growth has followed client need rather than ambition alone, taking the practice from its founding underdog position to one of the country's largest and most profitable law firms.
