Blank Rome’s six-month-old Chicago outpost has added two new partners in less than a month, including the head of another out-of-town firm’s Windy City office and a longtime federal prosecutor.

Craig Culbertson, who led McGuireWoods’ Chicago office and was an executive committee member at the firm, is the seventh hire for Blank Rome in the city. He compared his latest move to his decision to join McGuireWoods nearly 20 years ago, when that firm also had fewer than 10 lawyers in Chicago. It now counts close to 100.
