Robins Kaplan on Thursday announced it was adding four federal civil rights and personal injury lawyers from Minneapolis boutique Gaskins Bennett, which is winding down as that firm’s remaining managing partner enters semi-retirement.

The move marks the latest expansion for a national firm in the Minneapolis market, bringing Robins Kaplan a quartet with strong regional reputations and high-profile cases under their belts while highlighting the limits to longevity for boutiques as their founders exit the practice.
