Three years after opening up an office in Chicago, Fox Rothschild is doubling its presence in the Windy City through the acquisition of Shaw Fishman Glantz & Towbin.

Philadelphia-based Fox Rothschild could already boast 18 attorneys in Chicago, up from four when it announced the office in April 2015. But according to chairman Mark Silow, the size of the Chicago legal market demanded that the firm expand further.
