Founded in 1970 as a four-lawyer subrogation and recovery practice, Cozen O'Connor has grown into a full-service law firm with more than 1,000 attorneys operating across 35 offices in North America and Europe. The firm's expansion has been driven by client demand, beginning with the launch of corporate transactional practices in 1994 to handle landmark deals and diversify its legal services.
The firm's practice areas include insurance and corporate/transactional law, and it has developed ancillary businesses such as Cozen O'Connor Public Strategies, COSECURE, and CODISCOVR. Its founding subrogation and recovery practice remains a core part of the firm's operations.
Cozen O'Connor's culture is characterized by intellectual rigor, calculated risk-taking, and strategic expansion. The firm describes itself as having a willingness to challenge the establishment, with growth that has been driven by client demand rather than ambition alone.
