For Cozen O'Connor, 2017 has been a busy year.

And it's just one more year on the path toward creating a much larger firm with a powerful, national brand, said CEO Michael Heller. In the next five years, he said, he hopes to continue diversifying Cozen O'Connor's revenue stream, and to grow head count to between 700 and 1,000 lawyers.

Cozen O'Connor ended 2016 with 563 lawyers. In the last nine months, it added a net 28 partners and nine associates, according to ALM Intelligence's Rival Edge.
