Mark Weinberger on Dateline: Escape, Capture, and New Indictment

Mark Weinberger, the former Indiana sinus surgeon featured on NBC’s Dateline, is the doctor who performed hundreds of unnecessary surgeries at his Merrillville clinic, disappeared from a yacht in Greece in 2004, hid in the Italian Alps for five years until a woman who recognized him from a Dateline segment turned him in, served federal prison time for healthcare fraud, and was indicted again in November 2025 on new Medicare fraud charges in South Carolina.

The Sinus Clinic and the Surgeries

Weinberger opened the Weinberger Sinus Clinic in Merrillville, Indiana, in 2002, four years after starting practice as an otolaryngologist in the area.¹ The clinic was busy and profitable, taking in more than $3 million a year.² He saw more than 100 patients a day and performed between 7 and 15 surgeries a week by 2003 and 2004. Attorneys who later represented his patients said roughly 90 percent of them were told they needed surgery at their first appointment.

The operations themselves caused harm. Patients said Weinberger used an outdated technique that drilled holes in their sinuses and caused mucus to drain inward, often triggering chronic sinusitis. Many left worse than they arrived.³¹⁴

More than 350 malpractice claims were eventually filed against him. The bulk were resolved through a $55 million global settlement paid by the Indiana Patient’s Compensation Fund covering 282 claimants, with a separate $11 million settlement later covering roughly 60 more.³⁵ The Indiana Medical Board permanently revoked his medical license in 2005.⁶

Disappearing From a Yacht in Greece

In September 2004, Weinberger and his third wife, Michelle Kramer, traveled to Greece for her 30th birthday. On September 21, while the couple was aboard a 79-foot powerboat docked at a marina on Mykonos, Weinberger slipped away as Kramer slept. He took his passport and money he had hidden, paid a taxi driver to bring him to an airport, and boarded a private jet. Kramer was left behind with only her passport and 2,000 euros.⁷

The escape had been planned. In the months before, he had purchased diamonds, pulled a large sum out of his business, and shipped survival gear, including a water filtration system, to Europe from a room at his clinic that staff called “the scary room.”⁸ Investigators later traced his movements through Monaco, China, and France.²

He eventually settled in Courmayeur, a town in the Italian Alps near Mont Blanc, and lived under the alias “Mark Stearn.” He told locals he was writing a survival book. He rented an apartment for a while, then stopped paying rent in August 2009 and moved to a tent on the southern slopes of Mont Blanc at about 6,000 feet, living on tinned and dried food and melted snow in temperatures that dropped to minus 18 Celsius.⁸

How Dateline Led to His Capture

Weinberger’s years as a fugitive ended because of a woman named Monica Specogna. Specogna had met him at her parents’ grocery store in Courmayeur, and the two began a romantic relationship in early 2009. She knew him only as Mark Stearn. After a friend raised concerns, she came across an online Dateline segment about the missing Indiana doctor and recognized the man she was seeing. She reported him to the Italian Carabinieri.⁷

On December 15, 2009, a Carabinieri team led by a local mountain guide found Weinberger in his tent near Mont Blanc. Officers used a ruse, telling him he had to come to the station in Courmayeur to sign paperwork. When they confirmed his identity and moved to arrest him, Weinberger pulled a small knife concealed in his underwear and stabbed himself in the throat. He was taken to Molinette hospital in Turin.⁸ Authorities believe he had been trying to cross into Switzerland when they caught him.⁹ He was extradited to the United States about two months later.⁷

Federal Conviction and Prison

Weinberger pleaded guilty to 22 counts of healthcare fraud for billing patients for sinus surgeries he never performed. The case was heard in the U.S. District Court for the Northern District of Indiana in Hammond. Chief Judge Philip Simon rejected an initial four-year plea deal in April 2011 after noting that insurance records identified at least 53 additional patients billed for surgeries beyond the 22 in the plea.¹⁰

In October 2012, Judge Simon sentenced Weinberger to 84 months in federal prison, followed by two years of supervised release, and ordered approximately $108,000 in restitution. The sentence went above the federal guideline range of 37 to 46 months; the judge applied an enhancement for his flight from the country.¹¹ He had already served roughly 37 months at the Metropolitan Correctional Center in Chicago by then.

Life After Prison as the “Yoga Doc”

Weinberger was released to a halfway house in Florida in 2014, having served under five years of the seven-year term.⁶¹²

Former patients told NBC they were furious. Kayla Thomas, who had a needless sinus surgery as a child and grew up to become an internist and pediatrician, said Weinberger “thinks that he’s above the law” and “hasn’t learned anything.” Her mother, Valerie Thomas, called him a “monster” and said he was “in Florida living his best life.”⁶

The 2025 Medicare Fraud Indictment

On November 18, 2025, a federal grand jury in Greenville, South Carolina, returned a five-count indictment charging Weinberger, now 62 and living in Lake Worth Beach, Florida, with health care fraud, wire fraud, conspiracy to commit health care fraud, and conspiracy to commit wire fraud.¹³

The indictment alleges that between July 2019 and April 2021, Weinberger ran a Florida-based durable medical equipment company called Cypress Health Solutions LLC. His prior conviction had excluded him from Medicare for at least 15 years, barring him from owning or managing any Medicare-enrolled company, and prosecutors say he submitted a false enrollment document to hide his ownership. He is accused of conspiring with a Greenville call-center operator to generate fraudulent orders for medically unnecessary orthotic braces; Cypress submitted roughly $6.7 million in false claims and was paid about $3.4 million by Medicare.¹³¹⁴

Weinberger was arrested in the Southern District of Florida on November 6, 2025, released on a $150,000 personal surety bond, and waived his removal hearing, with the case transferred to the District of South Carolina.¹⁵ The wire fraud counts carry a maximum of 20 years each; the health care fraud counts carry up to 10 years each. The FBI and the U.S. Department of Health and Human Services Office of Inspector General are investigating.¹³

Where to Watch the Dateline Episodes

The main Weinberger story appears in Dateline: Secrets Uncovered, Season 13, Episode 9, titled “A Wanted Man,” which follows the practice, the disappearance, Monica Specogna’s role in his capture, and the conviction.⁷ A 2021 Dateline follow-up, produced with NBC Chicago’s investigative team, covered his post-prison life in Florida and interviewed former patients including Kayla Thomas.¹² An earlier segment on his disappearance is what Specogna found online and used to identify him, which ended his years as a fugitive.
