Los Angeles-founded global law firm O’Melveny & Myers, continuing a corporate lateral hiring spree, has now taken on a mergers and acquisitions and private equity partner from Ropes & Gray in San Francisco.

C. Todd Boes, who had been at Ropes & Gray for past 25 years, will join as a partner in the firm’s corporate group. The firm has already added four other lateral hires to that practice in the last six months.
