Just over two years after joining Norton Rose Fulbright to help open its Pittsburgh-area office, energy and environmental compliance attorney Kenneth Komoroski has left the firm to join Morgan, Lewis & Bockius in Pittsburgh along with a team of associates.

“I’m very excited to be moving to a high-caliber law firm and to further grow our environmental, shale, oil and gas practice,” Komoroski said.

According to a Morgan Lewis press release, Komoroski trained as an engineer and represents clients in midstream, downstream and oil and gas production and exploration companies.

He also handles cases involving land use and zoning, permits, water usage and wastewater treatment, environmental issues, royalties, lease terms and local ordinances, among other litigation areas, the press release said. His clients are from all over Pennsylvania, Ohio, West Virginia, New York and Maryland, and he also worked to develop the Marcellus and Utica shales, the release said.

Komoroski said that, although Morgan Lewis already has an established practice dealing with oil, gas and shale litigation — particularly in Houston, where the firm has about 75 attorneys — his addition to the firm will help it expand its East Coast presence.

“This will be a further expansion into the area of oil and gas of the Marcellus, Utica and Upper Devonian shale,” he said.

In April 2011, Komoroski was one of six attorneys to leave K&L Gates and join Fulbright & Jaworski before the firm merged with Norton Rose in June to become Norton Rose Fulbright. Komoroski had been brought in to open the firm’s office in the Southpointe business park in Washington County, Pa.

Komoroski had served as the partner-in-charge of that office.

As of Monday, according to Norton Rose Fulbright’s website, there are now three partners, three associates and a senior associate in the office.

Komoroski said that Norton Rose Fulbright’s recent merger did not have an impact on his decision to move to Morgan Lewis.

“That was a great combination for both firms,” he said. “This was an opportunity to join a very well-established firm, particularly in the Northeastern U.S. with an existing oil and gas practice.”

Jami Wintz McKeon, who was recently elected to take over as chairwoman of Morgan Lewis next year and currently leads the firm’s litigation practice, said in a press release that Komoroski’s practice is “a natural fit for our firm’s platform.”

“He adds depth to our already robust environmental litigation services and a strategic complement to other practices globally, including our practices focusing on transactions, regulatory issues, and private equity in the energy industry,” McKeon said.

A spokesperson for Norton Rose Fulbright did not respond to a request for comment Monday afternoon.
