Dorsey & Whitney has elected Kim Severson to serve as chair of its 11-person policy committee, making the veteran tax lawyer the first woman to lead what amounts to the board of directors for the 105-year-old, Minneapolis-based Am Law 200 firm.

Severson has served on the partner-elected policy committee for about three-and-a-half years, and she will serve at least one year in the chair position. The chair, nominated and voted on by the policy committee members, is elected once a year and has a term limit of two years. Severson replaces New York-based trial partner Richard Silberberg, who had served in the chair role the past two years.
