Michael Woronoff, head of Proskauer Rose’s West Coast corporate and securities practice, is joining Kirkland & Ellis in Los Angeles, bringing several other lawyers with him, several industry sources have said.

The group, including Woronoff and at least four other partners, is expected to join Kirkland’s Los Angeles office within the next month, according to sources with knowledge of the firms.  Kirkland declined to comment on the record.

Proskauer also declined to comment on the departures.

Woronoff served as the co-head of Proskauer’s global mergers and acquisitions and private equity groups. He joined Proskauer in 2004 to help the firm build out its corporate and securities practice on the West Coast. Before that, he was a co-founder at Shelter Capital Partners, a Southern California-based private equity fund that invests in technology businesses.

While at Proskauer, one of Woronoff’s biggest clients was private equity firm Ares Management. He was lead counsel for Ares’s $216 million initial public offering in 2014. And in 2011, he advised Ares and the Canadian Pension Plan Investment Board on their $1.6 billion acquisition of 99 Cents Only Stores.

Woronoff has been practicing in Los Angeles since 1985, when he graduated from the University of Michigan Law School. He started his career in the Los Angeles office of Skadden, Arps, Slate, Meagher & Flom, where he spent 15 years.
