Federal courthouse in Boston, where the US Attorney's Office has offices

Boston White Collar Criminal Defense

Boston's federal court—the United States District Court for the District of Massachusetts—is home to sophisticated white-collar prosecutions involving securities fraud, healthcare fraud, government contractor fraud, and increasingly, cryptocurrency enforcement cases. The US Attorney's Office for the District of Massachusetts, with specialized units focused on financial crimes and public corruption, works closely with the FBI's Boston Field Office, SEC's Boston Regional Office, and IRS Criminal Investigation to build complex cases against individuals and corporations. Boston's tight-knit legal community means that relationships, reputation, and local knowledge matter enormously in white-collar defense.

At Dynamis LLP, our founding partner Eric Rosen spent years as a federal prosecutor in the Boston US Attorney's Office, including leading the nationally-publicized Operation Varsity Blues investigation. We know the Assistant US Attorneys, the federal judges, the SEC enforcement staff, and the local dynamics that influence case outcomes. Our Boston white-collar practice has secured remarkable results: the dismissal of a 20-count indictment days before trial, successful pre-charge negotiations that prevented criminal charges, and favorable sentencing outcomes even in cases where convictions occurred. We represent clients in Boston federal court across healthcare fraud, securities violations, insider trading, cryptocurrency enforcement, public corruption, and tax fraud cases. Whether you're a healthcare executive facing False Claims Act allegations, a financial professional under SEC investigation, or a business owner responding to a federal grand jury subpoena, our team provides aggressive, knowledgeable representation grounded in deep understanding of how the Boston federal enforcement apparatus operates.

We prosecuted these cases before we defended them.

Dynamis was founded by former federal prosecutors. Our partners tried cases for the government in the District of Massachusetts and elsewhere before opening this firm. We know how a federal investigation is built in Boston because we built them — which charging decisions get made in the Moakley Courthouse, how the U.S. Attorney's Office evaluates a proffer, and what a line AUSA tells a supervisor when a case is weak.

That is the difference between a lawyer who has read about federal practice and one who has run it.

The call that matters is the first one

Most white collar cases are decided before an indictment exists. By the time charges are returned, the government has spent months or years assembling documents, flipping cooperators, and locking in testimony. The window to shape the outcome is the investigative window — and most people do not know they are in it.

If any of the following has happened, the window is open now:

  • A federal agent appeared at your home or office and asked to talk

  • You received a grand jury subpoena for documents or testimony

  • Your employer told you that outside counsel wants to interview you

  • The SEC sent a document request or a Wells notice

  • You learned a colleague has been interviewed and you have not been

Do not answer questions. Do not delete anything. Do not assume that cooperation and candor are the same as an interview without counsel present. Call us.

What we defend

Securities fraud and insider trading. Market manipulation, accounting fraud, Rule 10b-5 charges, and parallel SEC enforcement. We have taken these cases to verdict against the government.

Health care fraud. False Claims Act exposure, kickback allegations under the Anti-Kickback Statute and Stark Law, and DOJ investigations of physicians, practice groups, and device and pharmaceutical companies. Massachusetts is an aggressive district for health care enforcement.

Wire and mail fraud. The government's default charge. Its breadth is the reason it is charged — and the reason it is vulnerable to attack on the elements.

Public corruption and bribery. Federal program bribery, honest services fraud, and the constitutional limits that the Supreme Court has repeatedly imposed on those theories.

Money laundering and financial reporting. Structuring, unlicensed money transmission, and BSA obligations.

Government investigations and internal investigations. Responding to subpoenas, negotiating scope, managing parallel proceedings, and conducting internal investigations that hold up when the government reads them.

Crypto and digital asset enforcement. DOJ, SEC, and CFTC actions involving exchanges, tokens, and digital asset funds.

Results

  • Won an across-the-board trial victory against the SEC for a client charged with securities fraud.

  • Secured dismissal of all charges in a federal securities fraud prosecution arising from social media trading activity.

  • Obtained a non-incarceration sentence in a securities fraud case where the government sought prison.

  • Ended a federal investigation of a Massachusetts physician without charges.

  • Reduced federal charges to a misdemeanor in a PPE misbranding prosecution.

Why clients hire us in Boston

We try cases. Most white collar lawyers negotiate. Some have never picked a jury. The government knows which is which, and it prices its offers accordingly. Our willingness to try a case is the leverage that produces better resolutions in the cases that never reach trial.

We are small on purpose. Partners handle the work. There is no leverage pyramid here and no first-year associate learning federal practice on your matter.

We know the district. Judges in D. Mass. have preferences and patterns. So does the U.S. Attorney's Office. That knowledge is not transferable from another city.

We handle the civil case too. White collar exposure rarely arrives alone. A criminal investigation brings SEC enforcement, shareholder litigation, and employment claims behind it. We litigate all of it, which means no one is coordinating strategy across three firms with three different theories.
