Most Cases Are Decided
Before They Are Charged.

White collar and federal criminal defense for companies, executives, boards, and licensed professionals, from the first subpoena through verdict.

An Investigation Does Not Begin With an Indictment.

It begins with a subpoena, a search warrant, an agent at an employee’s door, or a civil investigative demand that arrives without explanation. What happens in the months before charges are filed usually determines whether charges are filed at all.

We do not wait for the government to build its case. We move to assess exposure, identify what the government is likely to have and where it is likely to be wrong, and where the facts allow it, we resolve the matter before anything is filed. Where they do not, we prepare the case for trial from the first week, because the quality of that preparation sets the terms of any resolution.

We Have Worked Both Sides of This Courtroom.

Our lawyers include the former United States Attorney for the Southern District of Florida, a former Deputy Chief of the Health Care Fraud Unit in that office, a former Deputy Chief of the Violent Crimes and Gangs Unit, former Federal Public Defenders, and former partners at one of the nation’s largest firms.

That combination matters more than the sum of it. Our lawyers have seen the case from both directions, and it shows up in how early we can read where one is going.

White Collar and Regulatory Defense.

We represent publicly traded corporations, boards of directors and compliance committees, officers and directors, and licensed professionals in the matters where a charge alone can end a career or a company. Securities fraud. Bank fraud. Mail and wire fraud. Money laundering. Tax fraud and evasion. Public corruption. Foreign Corrupt Practices Act investigations. Environmental crimes.

White collar investigations rarely arrive alone. They come alongside regulatory proceedings, and often alongside private class actions and shareholder derivative suits brought by plaintiffs reading the same headlines. We coordinate the defense across all of it, because a position taken in one forum is evidence in the next.

A Trial Practice Is Perishable.

The only way to keep one is to use it. We try criminal cases: fraud, narcotics and money laundering conspiracies, firearms charges, and the broader run of federal prosecutions, principally in the Southern District of Florida, along with serious felony matters in Florida state court.

These cases are won on the evidence rather than the theory. Cooperating witnesses with agreements to protect. Wiretaps with authorization, minimization, and sealing problems. Cell site and device data that says less than the government tells a jury it says. Geofence warrants that swept up everyone who happened to be nearby. We work that record early, and we cross examine the analysts who interpreted it.

Serious state felony matters run on the same engine: contested forensic evidence, witnesses with reasons to shade their testimony, and a trial date that has to be treated as real from the first appearance.

National Security and Sanctions.

Sanctions and export control enforcement sits where corporate compliance meets criminal exposure. A payment that looked routine becomes an International Emergency Economic Powers Act charge. A counterparty turns out to be designated. A compliance program that satisfied the auditors does not satisfy the Office of Foreign Assets Control.

We defend individuals and companies in matters involving economic sanctions, OFAC designations and enforcement, export controls, and related fraud and money laundering charges, including cases with foreign nationals, foreign financial institutions, and evidence located abroad. We handle Foreign Agents Registration Act matters and material support charges, and we litigate cases involving classified evidence under the Classified Information Procedures Act.
