They showed up looking like delivery guys, lugging shopping bags from a Whole Foods Market.When they knocked on the door of David Berger’s home in Ukrainian Village, he let them in.But the bags weren’t filled with groceries. They were stuffed with stacks of cash, prosecutors say, money Berger wa s helping launder for a Mexican cocaine-trafficking ring in 2021.Berger wasn’t just another middleman in a drug scheme. He was also becoming a major player in Illinois’ state-regulated cannabis industry.Now, he's a convicted felon. Yet Berger, 42, who was found guilty late last year of federal money-laundering charges, remains licensed by the state of Illinois to be in the legal weed business. And he continues to be affiliated with a network of dispensaries operating in Chicago, the suburbs and downstate under the Ivy Hall name.Steven Johnson, spokesman for the Illinois Department of Financial and Professional Regulation, which licenses marijuana shops, says the agency “is deeply concerned by this verdict of illegal conduct.“The department is closely monitoring this case, as it takes seriously all convictions pertaining to criminal activity,” Johnson says. “The department will take next steps in accordance [with] state law.”Records show Berger is listed as a manager of four of the Ivy Hall dispensaries and a registered agent for eight of them.One store — in Bucktown — was hailed as part of Illinois’ social equity push to bring Black and Latino entrepreneurs into the cannabis business. Gov. JB Pritzker showed up to celebrate the dispensary's opening in 2022.In a state newsletter that year, Berger was listed as chief operating officer of Ivy Hall, which was called "a collective of social equity licenses banding together to create a meaningful retail footprint."Still, Illinois’ cannabis regulatory system is so murky that it’s nearly impossible to pin down who actually owns what through public records.What is clear: Berger still holds a state license as a “registered adult use principal officer,” a role reserved for the top brass of cannabis businesses — owners, executives and key decision-makers.A spokesperson for Berger declined to comment on his role in Ivy Hall. The Ivy Hall dispensary at 1720 N. Damen Ave. in Bucktown.Zubaer Khan / Sun-Times Tomatoes, broccoli — and cocaineThe federal case against Berger stemmed from a broader investigation into what prosecutors described as a Midwestern cocaine distribution pipeline.At the center was Oswaldo Espinosa, known as “Ozzy,” who was accused of moving narcotics north from Mexico in produce shipments — broccoli, tomatoes and avocados — and returning millions of dollars in cash to Mexico in the same trucks.But when speed mattered, authorities say, the operation went airborne.That’s where Berger came in.According to prosecutors, he arranged about 20 private jet flights over a seven-month period using money from drug sales. They say he was paid $3,000 per flight.The method, described in court, was straightforward. Strangers came to his door with tens of thousands of dollars, most of that in $100 bills fastened with rubber bands. Berger used his American Express card to book charter flights, then broke down the piles of cash delivered to his home into smaller ATM deposits in his Chase Bank accounts — each under $10,000 to dodge federal reporting requirements.In all, prosecutors say, he made 135 transactions totaling $314,000.“He never deposited it all at once,” a prosecutor told jurors. “He knew that would trigger the bank.”The jets ferried bricks of cocaine to Gary/Chicago International Airport and millions of dollars of drug proceeds back to an airport in Texas near the Mexico border, authorities say.A friend in needBerger booked the flights through a Miami charter company run by Dimitri “Dean” Katamanin, a childhood friend. Dimitri “Dean” Katamanin.U.S. District Court Before Berger was charged in 2023, he spoke of his friend when questioned by Internal Revenue Service agents: “It’s kind of a long story, but he was going through a tough time mentally, and he’s like, ‘Can you help me book some flights?’”“You can’t just go to Expedia to find a private jet,” his lawyer, Patrick Blegen, explained to the jury at Berger's trial, according to a transcript.The feds didn't buy Berger's story.During the trial, prosecutors pointed to singer Miley Cyrus, one of the celebrity customers of Katamanin’s company, Jet 79.“Do you think Miley Cyrus was paying for private jets with rubber-banded cash in grocery bags?” Assistant U.S. Attorney Hanna Helwig asked jurors.Katamanin wasn’t charged. He died last year in a drowning accident in Los Angeles.A lengthy résuméIn court, Berger’s lawyer portrayed him as a legitimate businessman with a long résumé in energy and cannabis consulting.Berger attended Glenbrook North High School in Northbrook and Michigan State University, where he played hockey, and he later advised cannabis ventures across multiple states through his company, Birchwood Capital LLC.According to his résumé, he also was chief financial officer for a minority-owned cannabis group whose licenses were acquired by Verano Holdings. According to testimony, Berger was friends with Sammy Dorf, a co-founder of Verano, one of the biggest cannabis companies in the United States.Berger held a position with Invenergy, a renewable energy firm, at the time of his alleged crimes.His lawyer said Berger had worked as a bank teller in his youth and had experience navigating financial systems.“So he knows the rules,” Blegen said in court. “He’s not trying to avoid anything.”Assistant U.S. Attorney Andrew Erskine countered that that’s like saying people who know the speed limit never drive fast.Lamborghinis and Rolls-RoycesBerger was one of 18 people swept up in the drug investigation.Espinosa, described as the kingpin of the operation, lived large when he was in Chicago, cruising the streets in Lamborghinis and Rolls-Royces and even a yacht on Lake Michigan, according to testimony.At the same time, millions in drug proceeds were heading south.One associate, who referred to bricks of cocaine by the code name “tortillas,” said he moved at least $24 million in cash from Chicago to Mexico from 2019 through 2021, according to prosecutors. Oswaldo Espinosa of Mexico is a fugitive who’s wanted by the U.S. Drug Enforcement Administration.DEA According to testimony, a daisy chain of personal and business relationships linked Espinosa to Berger.Chicago businessman Elvin Shtayner testified he was friends with an exotic car dealer who introduced Shtayner to Espinosa.Shtayner owned Collision World, an auto repair company. His family also was involved in the taxi business and was associated with President Donald Trump’s onetime lawyer and fixer Michael Cohen.Shtayner said in court that he agreed to rent his Gold Coast condo to Espinosa for $11,000 a month. Shtayner said he introduced his friend Katamanin, the jet charter owner, to Espinosa.And Berger then booked flights for Espinosa's crew through his friend Katamanin's charter company.Shtayner, who testified for the prosecution, pleaded guilty to money-laundering charges last year.On the witness stand, he admitted he charged Espinosa tens of thousands of dollars to store cocaine in his family’s warehouse and introduced Espinosa to a woman who counted his drug money.Shtayner acknowledged that he hoped he could get a reduced sentence in exchange for his testimony. Under federal guidelines, he faces more than three years in prison.‘You may think he was a nut’Berger, who still says he did nothing wrong, is asking a judge to overturn his guilty verdict or order a new trial.In a court filing last month, his lawyer said prosecutors' accusations that Berger knowingly laundered drug money were “speculative.”“You may think he was a nut for taking this money,” Blegen had told jurors in his closing argument on Berger's behalf in December. “But he’s not guilty of what he’s charged with.”Despite his conviction, Berger remains licensed to sell marijuana in Illinois and is associated in business records with 10 dispensaries — the maximum number a company can operate under Illinois law. State officials won't say which ones, though, nor discuss specifics of Berger’s criminal case, citing “confidentiality provisions” of the state’s cannabis legalization law.The department could take disciplinary action — including suspending or revoking a license — if a principal officer like Berger is convicted of a felony. But that can only happen after someone is sentenced, meaning Berger’s effort to get his conviction thrown out has effectively forestalled that possibility. State Rep. La Shawn Ford, D-Chicago.Ashlee Rezin / Sun-Times ‘He should be banned’State Rep. La Shawn Ford, D-Chicago, sponsored a 2021 law that prioritized cannabis license applicants who had been arrested or convicted of low-level marijuana-related offenses. Ford says he thought it was “unfair” that people who had criminal convictions that didn’t involve cannabis were “written out of the chances of being owners” even after they were “reformed.”But he draws the line with a license owner like Berger who’s been convicted of a serious crime. Ford says Berger “should be banned” from the marijuana business “because he ran afoul of the law,” but he says he “should be able to come back” if his conviction ends up getting overturned.“We know that this person is convicted of a crime and he can still benefit from the industry,” says Ford, who’s running for Congress. “I think that that’s wrong.” FEW POT LICENSES DENIED IN ILLINOISOver the past decade, the state has shifted away from blocking felons from holding cannabis licenses. In 2015, Gov. Bruce Rauner’s administration had prohibited people with felony convictions for violence and drug dealing from getting medical marijuana licenses. Nowadays, though, few people are turned down for licenses in the legal cannabis industry and other state-regulated businesses because of convictions, records show.It’s part of an effort by the Pritzker administration to expand opportunities for communities disproportionately affected by the criminal justice system. “A criminal conviction alone should not stand in the way of an individual pursuing an occupational license,” Mario Treto Jr., secretary of the Illinois Department of Financial and Professional Regulation, said in a report issued last year. In 2024, the report noted, 11 of the 183 people who applied for an adult-use cannabis principal officer’s license had been convicted of a crime. None was denied a license.IDFPR posts monthly updates about disciplinary action taken against the state’s more than 9,000 cannabis license holders. Between January 2024 and January 2026, nine people and two dispensaries with cannabis licenses were disciplined. Only one case listed a clear-cut crime: theft. It wasn’t clear whether the other violations — such as failing to pay state taxes, selling to underage customers and not keeping track of cannabis products — were considered to be crimes. The reports didn’t provide details about the violations or whether they involved a conviction. The resulting disciplinary actions included suspensions, probation, fines, reprimands and the state’s refusal to renew cannabis licenses.
