A swanky scammer will spend a dozen years behind bars for his role in a multi-million dollar Ponzi scheme connected to a failing East End beach resort.

Brian Callahan, 48, received the sentence in Brooklyn federal court Friday.

The onetime Investment Manager milked 40 investors for $118 million, between December 2006 and February 2012.

Callahan used some of the cash to partially pay back victim investors — but also bankrolled a luxurious life including homes in Old Westbury and Westhampton.

"For years, Brian Callahan peddled lies to unsuspecting investors, causing some to lose their life savings, and to delay their retirements," said Acting Brooklyn U.S. Attorney Bridget Rohde.
