A California man was accused Thursday of masquerading as a state-licensed shrink in Brooklyn during a long-running scheme that defrauded at least a dozen patients — and even fooled the city Probation Department.

Glenn Payne, 60, was charged in a 55-count indictment that says he scammed more than $30,000 while illegally practicing neuropsychology on children, adolescents and adults from June 2012 through May 2018.

Payne didn’t accept insurance and instead charged patients between $60 and $250 a session, payable in cash, Chase QuickPay or electronic transfers, court papers say.

He ran the racket out of an office at 300 Cadman Plaza West in Brooklyn Heights, the Maple Medical office building in Prospect Leffert Gardens and the offices of the nonprofit Kings Against Violence Initiative at Kings County Hospital in East Flatbush, according to the Brooklyn District Attorney’s Office.

Blog posts on the Kings Against Violence Initiative website from 2012 and 2013 identify Payne as the associate director of the group.

Payne, who formerly lived in Glen Cove, Long Island, at the time, went “on the lam” last year when he learned that investigators were interviewing his patients, a law enforcement source told The Post.

He used aliases and changed his cellphones to evade authorities, and spent time in Las Vegas before settling in Los Angeles, where he was busted recently and extradited to New York, the source said.

Payne was allegedly assisted by his girlfriend and co-defendant, Vernette Tobierre, 46, who was busted in January.

She served as the office manager, arranging appointments and collecting payments from patients, according to the DA’s Office.

The top charge against each of them, third-degree grand larceny, carries a maximum sentence of seven years in prison.

Brooklyn DA Eric Gonzalez said an investigation was continuing into the couple’s alleged crimes, which also include scheme to defraud, unauthorized use of a professional title and endangering the welfare of a child.

“It is unbelievable that someone would put patients, including children, at risk by pretending to be qualified to diagnose and treat them,” Gonzalez said.

“The alleged conduct in this case is truly outrageous and potentially endangered vulnerable people.”

Payne’s patients included an unidentified “juvenile probationer” on whose behalf he repeatedly submitted paperwork “as proof of compliance with the terms of [the juvenile’s] court-ordered probation,” court papers say.

The documents allegedly included a July, 25, 2016, “progress note” and two “bio-psychosocial updates” dated May 1 and Aug. 14, 2017.

On Nov. 17, 2017, Payne also allegedly sent a “return to work” form to the employer of another, unidentified patient who paid him a total $2,820 between September 2016 and April 2018.

Payne “does not have the required licenses to practice psychology or medicine in New York State,” according to his indictment.

And while his LinkedIn profile claims that he a doctorate and Master of Public Health degree from UCLA and professional affiliations with Kings County Hospital and SUNY Downstate Hospital, none of that is true, court papers say.

Former neighbors in Glen Cove said that the couple had been raising two girls and that Tobierre moved out about six months ago.

“She was very, very nice but he was a mystery,” one neighbor said.

“She told everyone she was having domestic problems.”

Jeanine DiMenna, owner of The View Grill in Glen Cove said Tobierre worked for her as a baker for about six months during which Payne disappeared and their car got repossessed.

“At some point, she had no contact with him but she kept saying she felt sorry for him,” DiMenna said.

“She started asking everyone for money….I loaned her a little bit.”

The Probation Department said it was cooperating with the investigation and blamed its acceptance of Payne’s psychological reports on an unidentified Family Court judge.

“In the case in question, the juvenile was already under treatment by Payne prior to probation, and ordered by the court to continue that treatment,” spokeswoman Candace Sandy said.

A worker at the Kings Against Violence Initiative declined to comment.

Payne pleaded not guilty Thursday in Brooklyn Supreme Court, where he was ordered held on $100,000 bond or $50,000 bail pending a hearing on Oct. 30.

Court-appointed defense lawyer Michael Chessa said Payne was “adamant about fighting these charges.”

Chessa also denied that Payne fled New York to avoid arrest, saying he left due to unspecified “family issues.”

Tobierre was released without bond after pleading not guilty at her arraignment in January. Her next court date is Oct. 25.

Her defense lawyer, Rodney Doyle, declined to comment.
