Cozen O'Connor has taken a pair of New Jersey-based energy and utility lawyers from Windels Marx Lane & Mittendorf and launched an office in Newark.

Partner Gregory Eisenstark, once an in-house lawyer for Public Service Enterprise Group, and of counsel Michael Connolly work with utility companies in the state, including Jersey Central Power & Light and New Jersey Resources—clients they are bringing to Philadelphia-based Cozen O'Connor.

Eisenstark said he has long known Cozen O'Connor partner Ira Megdal, who is based in the firm's Cherry Hill office, and that they have “similar, but complementary practices.” Joining the firm in Newark, he said, “was just a good opportunity both for my practice and for Cozen.”

His practice is largely based in New Jersey, he said. He added that he has done some work involving the Federal Energy Regulatory Commission in Washington, D.C., though that's not a very active part of his practice now. Additionally, Eisenstark noted, he has done some work in Pennsylvania, which made Cozen O'Connor's platform attractive. The firm has offices in Philadelphia, Harrisburg, Pittsburgh, Wilkes-Barre and West Conshohocken.

Windels Marx is based in New York, but has substantial offices in Madison and New Brunswick, as well as one in Stamford, Connecticut.

Eisenstark became a partner at the firm in 2014, when he joined the firm along with Connolly. Before that, he was senior counsel at Morgan, Lewis & Bockius. He spent the earlier part of his career in-house and in government, including a decade at Public Service Enterprise Group, the parent company of electric utility Public Service Electric and Gas Co.

Before joining Windels Marx, Connolly previously served as vice president for law at GPU Service Inc. and its affiliates, Jersey Central Power & Light, Metropolitan Edison Co. and Pennsylvania Electric Co., according to his new firm.

“In a regulated field as complex as the utility industry, experience is the difference between success and failure,” Cozen O'Connor CEO Michael Heller said in a statement Monday. “Greg and Mike bring executive-level experience to clients on rate making, acquisition approvals, and rulemakings and are ideally suited to spearhead our Newark office.”

Newark is the firm's 28th office, and its second in New Jersey. The firm also has a location in Cherry Hill.

Cozen O'Connor has opened several new offices in the past two years, including Santa Monica, California; Richmond, Virginia; Pittsburgh; and Las Vegas. The Pittsburgh location opened in 2017, and has grown to nearly 30 lawyers since then, including two recent litigation hires.

Last year Cozen O'Connor opened an office in Vancouver started by subrogation partner Lisa Myers. But that location is no longer listed on the firm's website, and Myers is now listed as being resident in Seattle.

A spokesperson for Windels Marx did not immediately respond to a request for comment.
