The Boston Athletic Association has turned to Wilmer Cutler Pickering Hale and Dorr to handle legal issues stemming from last week’s bombings.

Wilmer’s Boston and suburban Waltham offices were both closed Friday, said litigation and IP partner William Lee, who is leading the representation. Last year he stepped aside as the firm’s co–managing partner under a prearranged succession plan.

Like much of the rest of the Boston region, Wilmer began to return to some sense of normalcy Monday.

Among its assignments will be helping the BAA, which released a statement last week expressing its sympathies to the families of those affected by the marathon bombings, cope with any legal fallout from the attack. The BAA, a registered nonprofit founded in 1887, has turned to Wilmer in the past in connection with a variety of pro bono and paying matters, such as contract and trademark issues.

Lee has run the race before and is familiar with long journeys. He once wore a white suit to a job interview in 1976 at old-line Boston firm Hale and Dorr. Fast-forward to 2004, when he was led the firm as it hammered out a merger with Washington’s Wilmer Cutler Pickering. The combined firm now boasts nearly 1,000 lawyers, attaining $1 billion in annual gross revenues for the first time in 2012, according to a recent report by The Blog of Legal Times, a Daily Report affiliate.

Another affiliate, the National Law Journal, reported that Goodwin Procter has been hired to run The One Fund Boston, a nonprofit being set up to coordinate donations to bombing victims.

Former Kaye Scholer partner Kenneth Feinberg has been tapped to administrate the fund. Goodwin Procter previously advised Feinberg in his role as administrator of a facility used to compensate victims of a disastrous 2010 oil spill in the Gulf of Mexico.
