Boston’s native legal market is sustaining aggressive recruiting by national firms, poaching homegrown transactional partners with the street credibility necessary for breaking through to the city’s tight-knit business community.

In the first half of the year, Am Law 100 firms Paul Hastings and Blank Rome and Connecticut-based midsize firm Wiggin and Dana started Boston offices by recruiting local dealmakers. Those firms follow in the footsteps of Orrick Herrington & Sutcliffe and Covington & Burling, whose Boston offices were built on teams recruited from locally based firms.
