The state has ordered dramatic changes at a Brooklyn LGBT social-services organization where a Health Department probe recently uncovered “weaknesses in fiscal policies and internal controls,” The Post has learned.

GRIOT Circle, founded in 1995 as Gay Reunion in Our Time to serve an older gay community, “is addressing the issues identified,” said department spokesman Jeffrey Hammond.

GRIOT did not respond to messages. Its 2010 tax returns show a budget drop from $324,000 to $269,000, and a $50,000 loss in assets — even as salaries shot up from $160,000 to $240,000.

“We’re going backwards,” a whistleblower told The Post. “A lot of the programs we’re supposed to have we don’t have; they’re not operating. It’s really one big mess. We tell people we serve 70 people a day; I haven’t seen 70 people a month. That’s a big lie . . . It’s a shame.”
