Kirkland & Ellis, moving quickly to build up the private equity group in its new Boston office, has hired two partners from Proskauer Rose, including a leader of Proskauer’s private investment funds group.

Kirkland was set to announce Wednesday that it has hired Sean Hill, the former Proskauer practice group co-leader, and Stephanie Berdik, also a former Proskauer corporate partner. Hill and Berdik, who joined the firm Monday, are the firm’s first investment fund lawyers in Boston.

Hill, 45, represents investment managers in business and operations, specifically, fund formation, and in structuring and executing secondary transactions. Berdik, 38, advises private investment fund sponsors on the structuring and establishment of funds and portfolio investment activities, including capital raising and fund regulatory and compliance matters.

Hill said most of his clients are moving with him to Kirkland, including Ares Management, Lexington Partners, WhiteHorse Liquidity Partners and THL Credit.

He added that he was attracted to the chance to join a new and growing office, much as he and Berdik joined Proskauer about 12 years ago, around the time it opened in Boston.

“It’s a chance to not only work with my clients on this global platform, but also work with their clients that need the expertise that Stephanie and I have in the buyout and credit space,” he said. “They [Kirkland] have the biggest funds practice globally, with more than 200 lawyers doing fund formation work, so the chance to plug into that network and platform was very exciting.”

With the new hires, Kirkland, which represents more than 400 private equity firms, now has eight partners in Boston.

Kirkland announced the opening of its Boston office last month in the Back Bay neighborhood after relocating three private equity partners from New York and Chicago: Armand Della Monica, Neal Reenan and Ian Bushner. John O’Neil, the New York-based leader of Kirkland’s investment funds group, will also join the group in Boston, Hill said.

In recent weeks Kirkland also brought on another private equity lawyer, Jason Serlenga, from Ropes & Gray, and hired Matthew Cohn, a former Weil, Gotshal & Manges senior associate, as a partner.
