ALBANY – The Rockland County assemblyman who last week resigned his seat in the wake of a gay sex scandal has also lost his partnership at an upstate law firm.

Ryan Karben [pictured] is no longer associated with Kurtzman Matera Gurock Scuderi & Karben, and his name is no longer part of the firm’s, said partner Howard Gurock.

The decision was made Friday, just hours after the news broke that Karben – an Orthodox Jew who is a married father of three – resigned his Assembly seat amid what sources said were allegations of improper sexual approaches to young male interns.

Gurock wouldn’t say whether the partners voted Karben out or if he resigned under pressure.

“Everything involved in that decision was done privately and internally,” he said.

Gurock said the last time Karben was in the office was Thursday, the same day he announced his resignation.

Karben joined the firm about three years ago, with partners hoping his connections as a sitting assemblyman and former county legislator would help bring clients.

“He had a nice rolodex of clients,” Gurock said.

Even when Karben told the partners Thursday he was resigning his seat, it wasn’t until Gurock was in his car the next day listening to the news on the radio that he heard the sordid details.

“I was very shocked,” he said. “I didn’t know it, if it’s true.”

Both the law firm and the Legislature have moved quickly to disassociate from Karben, removing his name from prominent locations.

Karben, according to sources, made improper approaches to interns, including getting at least one to watch gay porn with him.

The Post reported Saturday that he also stunned onlookers – including some of his colleagues – when he put his hands down the pants of a man at an Albany-area bar.

Karben leaves the Assembly with more than $500,000 in his campaign account, according to state filings in January.

Several lobbyists said Karben had become notorious for his aggressive pursuit of campaign cash from those looking to influence state lawmakers.

“He was outrageous in his aggressiveness,” said a well-known lobbyist.
