Three partners from Greenspoon Marder's New York City office who focus on international litigation, including office leader Keelin Kavanagh and two longtime colleagues, have moved to DLA Piper.

Kavanagh, Arthur Hoffmann and David Jaroslaw started at DLA on Tuesday as partners, after leaving Greenspoon Marder on Friday. The three lawyers have worked together since 2001, advising clients on "the intersection of science and law in product liability work," said Kavanagh.

Kavanagh said more lawyers and scientific experts could be joining them soon. A representative for DLA Piper said the firm was not prepared to share more names.

DLA Piper said the group has a strong background advising clients on risk assessment and litigation, particularly companies in the life sciences industry. They have represented product manufacturers—particularly, in Hoffman and Jaroslaw's cases, clients in the tobacco and e-cigarette industries—and have experience working with scientific and medical experts.

They've also worked on a broad array of commercial disputes. Banking, intellectual property issues, real estate and ride-sharing are all mentioned in the lawyers' biographies.

All three are qualified to practice law in New York, and Kavanagh is also admitted as a solicitor in Ireland and England and Wales. Hoffmann said they have advised clients in matters around the world, including in Ireland, the U.K., Poland, Germany, the Netherlands, Spain and India, often working closely with lawyers in those jurisdictions to help their clients make consistent arguments and pursue a consistent strategy around the globe.

Many of the group's clients, Jaroslaw said, "are in industries that have a heavy regulatory overlay. … A lot of it is dealing with how to do and say certain things before they become disputes."

Loren Brown, who co-chairs DLA Piper's global and U.S. litigation practices, said companies in rapidly changing industries like vaping "are increasingly likely to become targets for litigation and enforcement actions," and said the new partners were "well-positioned" to advise such clients on complex, cross-border cases.

In a statement, Greenspoon Marder's co-managing directors Michael Marder and Gerry Greenspoon said they wished the departed lawyers the best of luck. They said they had big plans for Greenspoon's New York office, which currently has 20 lawyers listed online.

"The firm remains very pleased with the continued growth of our New York office and we plan to continue strategic development and expansion in this key market," the duo said. "Additionally, we expect to announce new attorneys shortly and are thrilled with the high caliber of legal talent New York has to offer."
