The 100 Largest Law Firms In Pennsylvania (2024)

Size matters for law firms in this swing state.

Top 100There are many different and exciting ways to rank law firms. How prestigious are they? How much money are they making? How much take-home cash do partners earn? How big are they?

Yes, size continues to matter when it comes to Biglaw, and thankfully, the Legal Intelligencer recently unleashed its annual PA Law 100, a ranking of the largest law firms in Pennsylvania covering the previous calendar year. If you’ve ever wondered about headcounts, this is the ranking for you.

The top 10 biggest firms (numbers show attorneys in PA) are not surprising for those who practice in the region. Let’s take a moment to gawk at the Keystone State’s Biglaw behemoths:

  1. Cozen O’Connor: 296
