Because of the volume of M&A work in the energy industry, Kirkland & Ellis has launched an investment funds group in its Houston office, led by partner Matthew Nadworny, who moved to Houston from San Francisco this month.

“It’s complementary to everything we are doing. We are one of the premier private equity law firms in the country,” said Andrew Calder, a partner in Houston who is a member of the firm’s global management committee.

Calder said it’s helpful to have Nadworny in the Houston office to provide service locally. “We don’t want clients to wait for a lawyer to fly to Houston,” he said.

In 2013, Nadworny said, he moved from Chicago to Kirkland’s San Francisco office to help a small group of lawyers start an investment funds practice there. That practice has grown from four attorneys when he arrived in November 2013 to as many as 15 at present, he said.

“It’s a growing area, an area that increasingly gets more complex with SEC examinations and regulations,” he said.

Nadworny said the firm’s investment funds clients include Energy Capital Partners, Pearl Energy Investments, Warburg Pincus and LS Power. He said his work includes forming the funds that make acquisitions. According to the firm, over the last three years Kirkland has advised 280 investment fund sponsors on more than 380 funds.

Kirkland, which opened its Houston office in April 2014, has grown to 92 lawyers in Houston.
