Cozen O'Connor is a full-service law firm founded in 1970 in Philadelphia. It now ranks among the largest and most profitable law firms in the United States, with more than 1,000 attorneys working from 35 offices across North America and Europe. The firm has been listed among the Am Law 100. Practice areas include subrogation and recovery, insurance law, corporate transactional work, discovery and litigation support, and legal risk and claims solutions.
Beyond its core legal practice, the firm operates several ancillary businesses. Cozen O'Connor Public Strategies provides government relations and public policy advisory services. COSECURE and CODISCOVR were launched as part of a strategic expansion beyond core legal services, with CODISCOVR associated with discovery and litigation support work. These ventures were developed in response to client demand rather than as standalone ambitions.
The firm was established in 1970 by two litigators with complementary strengths and has grown from a four-lawyer practice through geographic expansion and strategic combinations, including a diversification into full-service law in 1994. Representative transactional work includes the Comcast Spectacor acquisition of the Philadelphia 76ers. Industry verticals served include insurance, corporate and M&A transactions, professional sports, and government relations.
