After 22 years at Greenberg Traurig, Howard Bregman, the former longtime head of the firm’s Palm Beach County operation, is defecting to Fox Rothschild.

Bregman, who founded Greenberg’s West Palm office in 1991, is moving next week and joining another recently departed Greenberg partner, Gary Dunkel.

Greenberg has become litigation-oriented with major financial institutions as clients, said Bregman, who does no litigation. He primarily represents residential, golf course and hotel developers in real estate transactions.

“A lot of my clients got into financial trouble in recent years and needed representation,” he said. “We couldn’t represent them, and we got conflicted out. Our office up here has become very litigation-oriented. There are very few transactional lawyers.”

Dunkel, a real estate, financial services and automotive litigator, did not return calls for comment by deadline.

Bregman said he was attracted to Philadelphia-based Fox Rothschild because he first came to South Florida in 1982 with another Philadelphia law firm, the defunct WolfBlock, to start its South Florida office.

“I have a lot of Philadelphia ties,” he said. “It’s like going back to my roots.”

Bregman ran Greenberg’s offices in Palm Beach County until a year ago. He said the West Palm Beach office has about 25 lawyers and the Boca Raton office about 15.

Richard Rosenbaum, CEO of Greenberg Traurig, said, “This was a good time for change, and we look forward with excitement to the next phase of growth, particularly for our leading corporate and real estate practices.”

Bregman said he does not expect any other Greenberg lawyers to follow him to Fox Rothschild.

Commercial litigator Mark Bideau took over in January 2012 as the managing shareholder of Greenberg’s West Palm Beach office, and he is co-managing shareholder of the Boca Raton office.
