Eric Rosen

Dynamis Founding Partner

Eric Rosen, a graduate of Harvard University and Columbia Law School, is a nationally recognized former federal and state prosecutor based in Boston and New York. Eric has a nationwide practice which focuses on white-collar criminal defense, corporate investigations, and complex civil litigation, with a specialty of novel and cutting-edge issues involving money laundering, market manipulation, securities fraud, cross-border litigation and investigations, crypto-assets and health care fraud. A seasoned courtroom advocate, Eric has tried, as lead and co-counsel, numerous criminal cases before federal juries (and arbitrators), in addition to conducting countless evidentiary hearings, sentencings, and other proceedings. Eric has also argued more than 50 appeals. When zealous, aggressive advocacy is called for, and when clients are embroiled in crises, Eric is retained.

Eric also has significant experience with overseas and cross-border investigations and prosecutions, including those involving alleged violations of the Foreign Corrupt Practices Act (FCPA) as well as the use of Mutual Legal Assistance Treaties (MLAT), both as a prosecutor and as defense counsel. As examples, as a prosecutor Eric conducted an investigation into FCPA violations by employees of PDVSA (Venezuela oil company), and as defense counsel Eric represented executives in the DOJ investigation into Odebrecht (Brazilian company) and its aftermath.

Eric served as an Assistant United States Attorney in Pittsburgh, Pennsylvania and Boston, Massachusetts for nearly nine years, and before that, he was an Assistant District Attorney in New York.  As a federal prosecutor, Eric prosecuted hundreds of defendants for a wide variety of federal crimes, including: wire and mail fraud, securities fraud, investor fraud, bribery, health care fraud, drug misbranding, money laundering, drug trafficking, racketeering, smuggling, and firearms offenses.   Eric developed significant expertise in securities fraud cases (including parallel investigations with the SEC), money laundering cases, bribery charges, and cases with international components.

As a federal prosecutor, Eric was the lead attorney in “Operation Varsity Blues,” the seminal case widely known as the college admissions scandal, one of the largest white-collar crime prosecutions in United States history. In March 2018, Eric, while leading an unrelated securities fraud investigation, began “Operation Varsity Blues,” the investigation that led, a year later, to charges against more than 50 individuals for fraud, bribery, racketeering and money laundering offenses related to the college admissions process. Eric’s work in the landmark prosecution, which generated significant worldwide media attention, was widely profiled by national and international publications and media outlets, including the Boston Globe, the New York Times, CNN, the Washington Post, Los Angeles Times, USA Today, and Netflix. In addition, Eric’s role as the lead prosecutor was chronicled in the July 2020 book “Unacceptable,” written by two Wall Street Journal reporters, Melissa Korn and Jennifer Levitz, the July 2022 book “Bad City,” by Los Angeles Times reporter Paul Pringle, and a 2024 podcast called “Infamous” put out by Sony Music Entertainment. Eric is also regularly called upon by the media to speak about other, non-Varsity Blues related, news, including publications such as Coin Telegraph, Fortune, Trading View, and the Wall Street Journal, amongst others.

Eric began his legal career by serving for three years as an Assistant District Attorney in Manhattan, followed by a one-year clerkship with federal Judge Robert P. Patterson, Jr. of the Southern District of New York.

Eric is currently based in Boston and New York but serves clients in federal and state courts nationwide. Prior to founding Dynamis LLP in June 2023, Eric was a partner at an elite litigation boutique with offices in New York, Boston and Miami.

Selected White-Collar Defense Engagements

Since leaving the Department of Justice in Boston, Massachusetts, Eric has represented dozens of individuals in all types of white-collar investigations, disputes and enforcement matters nationwide, involving federal, state and local regulators, often achieving remarkable and unprecedented success in many of the matters he has handled. Because of this, Eric’s clients frequently seek him out for their toughest and thorniest issues that require considered legal analysis and strategy.

Defending John Rybarczyk, aka “Ultra Calls,” a prominent Twitter influencer, who was arrested and charged with securities fraud together with seven others as part of the landmark “Atlas Trading” case. Seizing on the recent Supreme Court decision in Ciminelli v. United States, Eric succeeded in securing the dismissal of the Indictment on the eve-of-trial on behalf of both his own client as well as all the other defendants. The briefing and analysis that resulted in this rare event is detailed here. Eric is currently representing Mr. Rybarczyk before the Fifth Circuit Court of Appeals.

Defended a prominent doctor in health care fraud investigation by the FBI and Department of Justice in the District of Massachusetts. When Eric took over the case from prior counsel, the DOJ threatened to arrest the doctor the next week for charges related to the distribution of Schedule II controlled substances and health care fraud. Eric and his team fought back against the government, churning through tens of thousands of documents in the first week alone to create compelling presentations outlining the doctor’s innocence, and ultimately convinced DOJ to decline to press all charges - even forgoing civil sanctions.

Defending Steve Gallagher in first-of-its kind parallel investigation and charges brought by the Securities and Exchange Commission and the Department of Justice (Southern District of New York) alleging “scalping” as part of a “pump and dump” securities fraud scheme orchestrated over Twitter by an influencer using the screen name “Alex DeLarge.” Although client faced multiple years in prison after his arrest based on a charged loss amount of $1.2 million, Eric and his team ultimately achieved a “no jail” sentence for client in the criminal case (6 months) after convincing the government to drop nearly all the charges and adjust the loss amount down to just $21,000, a decrease of 98%. The parallel SEC remains ongoing in the Southern District of New York.

Defending prominent European banker in novel money laundering and FCPA case related to the DOJ’s sprawling Odebrecht investigation. Despite being threatened with nearly 20 years in prison upon his arrest at Newark Airport in the spring of 2021, Eric and his team convinced the DOJ to reduce the charges significantly, and ultimately, the individual pled guilty to a 371 conspiracy charge and was allowed to travel abroad prior to sentencing (which has not been scheduled).

Defending individual in District of Massachusetts investigation related to PPP-fraud. The DOJ accused Eric’s client of running a large-scale “middleman” operation related to the distribution of fake masks and PPP during the pandemic, as well as price gouging. Eric’s client was supposed to be arrested within weeks, after being represented by other counsel for more than a year. Eric took over the case two years ago in anticipation of taking the case to trial, but the DOJ still has not brought charges due to Eric’s zealous advocacy on behalf of his client..

Representing real estate owner in civil securities fraud complaint filed by the Colorado securities commission in state court in Colorado.   The Colorado securities commission, through the Attorney General’s office, filed a complaint against a real estate developer alleging that Eric’s client engaged in fraud amounting to a nearly $2 million loss to investors. After months of aggressive advocacy that pushed back on the Commission’s charges, the Commission relented and ended the case with no fine or monetary penalty and a “no admit no deny” resolution of the allegations.

Defending individual in parallel Department of Justice and Securities and Exchange Commission insider-trading charges in the District of Massachusetts. Eric represented a prominent entrepreneur from the day he was approached by the FBI in June 2021 through the present, with the case now having been transferred to the Southern District of Florida. After the individual dropped out of cooperation with the FBI, the DOJ retaliated and demanded a sentence of 48 months in prison based on multiple million dollar gain. Due to Eric’s zealous advocacy and oral argument at sentencing, Eric ultimately obtained a sentence of 12 months and 1 day in prison, far short of the Government’s demand. Eric’s advocacy and ingenuity at sentencing was deemed by Law360 to be amongst the “Spiciest Quotes Heard in Massachusetts courtrooms” in 2023.

Multiple agencies, from Head Start to NY’s Administration for Child Services, cut off funding for the school.
