San Francisco-based Sedgwick has lost its Washington, D.C., office, after its last two partners, Barbara Werther and David Mancini, moved to Troutman Sanders with one associate this week.

Their move follows several months of Sedgwick partners defecting to other firms.

Sedgwick's chairman told Law360 last week that the office would close for “cost efficiencies.” At this point, Sedgwick lists just one remaining lawyer in Washington: David Dorsen, a litigator, biographer and friend of the late U.S. Supreme Court Justice Antonin Scalia. Dorsen is of counsel at Sedgwick. He is in his 80s.
