Less than a month after opening an office in Boston, Quinn Emanuel Urquhart & Sullivan is building out its operations in the city with two additions from Ropes & Gray.

Harvey Wolkoff, who has spent roughly 40 years at the firm, will retire on Feb. 1 and become managing partner of Quinn Emanuel's newest office. The commercial litigator is bringing with him Ropes & Gray associate Brian Shaughnessy, who will come aboard as of counsel.

Wolkoff first joined Ropes & Gray in 1975 but left four years later to become a federal prosecutor in New York. He returned to the Boston-based Am Law 10 firm in 1982 and made partner two years later.
