Nelson Mullins Riley & Scarborough is merging with Florida firm Broad and Cassel, which will extend Nelson Mullins’ footprint along the Eastern Seaboard from Boston all the way to Miami.

The merger, set to take effect Aug. 1, will create a 725-lawyer firm with combined revenue of more than $500 million. The addition of Broad and Cassel, which has 150 lawyers in 10 Florida offices, will transform the super-regional firm, based in Columbia, South Carolina, into a super-duper-regional firm.
