Losses mount at Winston as Bostrom joins Freddie Mac

Winston & Strawn has lost its banking and finance rainmaker Robert Bostrom to Freddie Mac. Bostrom joins the US mortgage lender as its new executive vice president and general counsel.

The loss of Bostrom follows the defection of Winston’s former head of projects Chris McIsaac to Clifford Chance (CC) last week.

The move reunites McIsaac with former colleague Lori Bean, who left Winston to join the magic circle firm’s Washington DC office in December. McIsaac joined CC as co-head of the energy and projects group,

Bostrom will be responsible for all of Freddie Mac’s legal and regulatory capabilities, reporting directly to chairman and chief executive officer, Richard Syron. He will also be a member of the company’s executive team.

He was formerly managing partner of Winston’s New York office, a member of its executive committee and head of its financial institutions practice.

Bostrom joined Winston in 1990 and focused on corporate, finance, financial institutions and regulatory matters.
