Eric Goldstein, a securities litigator at Paul, Weiss, Rifkind, Wharton & Garrison, will resign from the firm’s partnership to become CEO of UJA-Federation of New York, a Jewish charitable organization with a budget of more than $200 million and 410 employees, the organization announced Thursday.

Goldstein, partner and chair of Paul Weiss’ pro bono committee, has been practicing at the firm for more than 30 years, focusing on securities class actions, white-collar crime, investigations and commercial disputes, with clients such as JPMorgan Chase, Citigroup, Morgan Stanley and News Corp. He also represented so-called “junk bond king” Michael Milken.

On July 1, Goldstein, 54, will succeed John Ruskay, who is stepping down after 15 years as executive vice president and CEO of UJA-Federation. UJA-Federation said Goldstein, who has served as vice chair of the organization, was the unanimous choice of its search committee.

“The CEO of UJA-Federation is an incredibly big job and full time job in every respect,” Goldstein said. “I have loved my practice,” he said, but “this is a rare opportunity to take on a role that is deeply meaningful to me, that has the ability to do enormous good.” He said the leadership transition comes as “there are extraordinary needs for a huge population of vulnerable people in New York and the world” but “in an environment of shrinking dollars.” He said, “We need to re-examine everything we do and confirm and ensure we’re doing it as well as we can.”

He said he is a big supporter of Ruskay and UJA’s position is strong, with an endowment of more than $900 million.

In a statement, Paul Weiss chair Brad Karp said, “We wish Eric every success as he launches this exciting new professional chapter. Our loss is UJA’s gain.”
