A Manhattan urologist pissed away $2 million in funds from the trade journal he co-founded with a partner and blew it on personal expenses including $24,000 for his daughter’s bat mitzvah and ski lessons at a posh Colorado resort, his miffed business partner says in a new lawsuit.

NYU chief urologist Herbert Lepor, who started MedReviews with his longtime friend and fellow doctor Michael Brawer in 1996, began using the company as his personal piggy bank after Brawer’s wife handed over the accounting duties in 2005, the Manhattan Supreme Court suit says.

Lepor started billing the business for everything from $21,500 for lighting at the 2010 bat mitvah plus a $2,600 dinner at Angus Club steakhouse the same weekend as the celebration, according to court papers.

The 62-year-old Manhattan dad allegedly charged MedReviews for ski vacations in Beaver Creek and Vail on the company account. He paid Beaver Creek Ski School $660 on Dec. 25, 2014 and the Vail Club nearly $8,000 between 2015 and 2016, the suit says.

Other incidentals include $160 in WiFi for his Ocean City, Maryland beach house in 2014, and more than $1,500 at local eateries like the Green Turtle and The Shark on the Harbor between 2014 and 2015, court records show.

He also splurged on a $1,000 at a Buenos Aires ceviche restaurant La Mar in 2015, the suit says.

The Johns Hopkins University graduate even plundered company coffers for far-flung trips to Italy, Israel and Peru as well as a closer-to-home Boston Duck Tour, the suit says.

“Lepor caused MedReviews to deduct all of the payments as business expenses, notwithstanding that the expenses would not qualify under federal tax regulations because there is no supporting documentation showing the business purpose of the charge,” the suit says.

Brawer, a Seattle-based urologist, discovered the spending spree when Lepor tried to buy out his approximate 20 percent stake in the company for $50,000 last November, the suit says.

“To better assess the reasonableness of the proposal Brawer asked for a detailed review of the company’s financial records,” the suit says.

“After finally accessing and reviewing the QuickBooks records, Brawer first learned of Lepor’s ongoing scheme to treat himself to numerous personal expenses on the company dime,” the suit says.

He’s suing for $3 million including repayment of the expenses plus interest.

Lepor’s secretary said he was unavailable to comment because he was seeing patients.

“It’s just two doctors engaged in a pissing match,” said MedReview President Jeff Arnold, who said he’s investigating Lepor’s charges.

A spokeswoman for Brawer did not immediately respond to requests for comment.
