One of the best investments I make each year is continuing to train alongside lawyers who handle the nation's most complex federal criminal cases.

While federal death penalty cases represent only a small part of my practice, the training and collaboration involved strengthen every aspect of my federal criminal defense work.

The most complex federal cases—whether capital prosecutions, large white-collar investigations, healthcare fraud, public corruption, or multi-defendant conspiracies—share many of the same demands: mastering enormous volumes of evidence, developing compelling mitigation, coordinating multidisciplinary teams, and crafting a strategy that tells the client's complete story.

Spending time with some of the country's most experienced federal defenders, mitigation specialists, investigators, and experts is a reminder that the best advocacy is rarely the product of a single lawyer. It's the product of a disciplined team united by a common strategy and a shared commitment to achieving the best possible outcome for the client.

I'm grateful for the opportunity to learn from outstanding colleagues across the country and to bring those lessons back to every client I represent.

In federal court, a “win” doesn’t always look the way people expect.

Recently, partner Talmage Newton secured Deferred Prosecution Agreements in two separate federal cases — one involving allegations of money laundering and the other involving allegations of white collar fraud.

A deferred prosecution agreement is rare. It allows the government to pause a case and place a client on a period of supervision. If successfully completed, the charges are dismissed.

In a system where federal convictions are the norm — not the exception — outcomes like this require early strategy, credibility with prosecutors, buy-in from the judges, and creative problem-solving.

Federal defense isn’t just about fighting cases. It’s about finding the path that protects your future.

ASSAULT CHARGES DISMISSED: After conducting our own investigation, our team identified and interviewed eyewitnesses the police never spoke with and we were able to uncover critical evidence that contradicted police accounts of the event.

Our independent investigation provided critical context and evidence, allowing prosecutors to see the case clearly — and dismiss the charges.

Great results don’t happen by accident. They come from experience, resources, and a commitment to finding the truth. Our firm invests in the investigation necessary to protect our clients when it matters most.

Federal Gun Case — Voluntarily Dismissed!

After a thorough investigation and detailed presentation of the defense, the prosecution agreed they could not prove guilt beyond a reasonable doubt. The result: a rare voluntary dismissal of a federal fi****ms case.

Federal criminal cases are not dismissed lightly. This outcome required digging into the facts, challenging assumptions, and forcing the government to confront weaknesses in its proof—before a jury ever had to.

This is why experience matters in federal criminal defense. Careful investigation, strategic advocacy, and knowing when and how to engage the prosecution can make all the difference. Results like this don’t happen by accident.
