Proskauer has lost some 20 attorneys to Kirkland & Ellis in Los Angeles, including the West Coast head of its corporate and securities practice, as Kirkland launches a new transactional team.

Michael Woronoff, who also helped run the private equity and M&A group at Proskauer, will lead the new team at Kirkland along with partners Monica Shilling, Philippa Bond, Jonathan Benloulou, Anne Kim, and Chris Wu.

Jeffrey C. Hammes, chairman of Kirkland’s Global Management Executive Committee, said in a statement that the six new partners are a “formidable group with incredible talent, outstanding reputations and a strong team ethos.”

“That’s a very exciting and attractive combination that will benefit clients as well as our teams in Los Angeles and around the world,” Hammes added. “We look forward to integrating them into our top-tier private equity/M&A platform.”

The attorneys have experience representing clients in a wide variety of transactional matters, including private equity, M&A, capital markets, business development companies, governance and tax matters.

In recent years, Kirkland has hired a number of big name private equity lawyers from competitor firms.

Among them are Sandra Goldstein, a leading litigator in the mergers and acquisitions space, who came to Kirkland in the spring of 2018 from Cravath, Swaine & Moore.

Goldstein was the second Cravath partner to join the firm last year. Eric Schiele, an M&A attorney who’s represented such top-drawer clients as Disney and Time Warner, climbed on board in early 2018.

Before joining Proskauer, Woronoff was a principal of Shelter Capital Partners, a Southern California-based private equity fund that invests in technology businesses. He’s also worked at Skadden, Arps, Slate, Meagher & Flom.

He’s worked on matters including Turner Broadcasting’s acquisition of several businesses, among them MGM and Hanna-Barbera; the formation of Frank Sinatra Enterprises, LLC, a joint venture between entities owned by the family of Frank Sinatra and Warner Music Group; and acquisitions and dispositions by numerous private equity funds including funds managed by Apollo and Parthenon Capital.

Kirkland & Ellis is global law firm with 2,500 attorneys in 15 offices around the world.
