Federal Criminal Defense Attorney

Facing a federal investigation or indictment? Strategic, trial-ready federal defense for professionals and executives. Confidential review.

A federal investigation rarely announces itself with a dramatic arrest. It often begins quietly: a subpoena, a knock from federal agents, a letter from the U.S. Attorney's Office, long before any charge is filed. By the time most people grasp the scope of what is happening, the government has often built its case for months or years. That imbalance is why early, strategic counsel matters more in federal matters than almost anywhere else in the system.

If you received a target letter, were contacted by federal agents, or learned a grand jury is examining your conduct or your business, waiting to see what happens is often the costliest decision you can make.

What Is at Stake

Federal cases run on different rules, timelines, and consequences than state court, and the exposure is often greater on every dimension.

Target letters and investigations. A target letter from a U.S. Attorney's Office signals prosecutors believe they have evidence connecting you to a federal offense. Receiving one does not make charges inevitable, but it means the investigation has reached an advanced stage, and how you respond can shape everything that follows.

Grand juries. Federal felony charges generally proceed through a grand jury, which hears evidence from prosecutors and decides whether probable cause exists to issue an indictment. Grand jury proceedings are one-sided by design; the defense generally has no formal role in that room, which makes the investigative stage before an indictment critical.

Indictment. Once a grand jury returns an indictment, the case moves into active federal litigation, with its own detention, discovery, and motion practices that differ meaningfully from state court.

Sentencing guidelines. Federal sentencing is shaped heavily by the U.S. Sentencing Guidelines, which calculate a recommended range based on the offense, criminal history, and case-specific factors. Understanding how these guidelines apply, and how early decisions can influence them, is central to federal defense strategy.

Professional and licensing consequences. For executives, licensed professionals, and public company officers, a federal charge can trigger parallel consequences: board inquiries, SEC or regulatory scrutiny, loss of security clearance, and reputational damage that starts well before any trial.

How the Defense Is Built

Investigation. A thorough, independent review of the government's likely evidence, witness exposure, and the scope of the investigation, often before any charge is filed.

Evidence challenges. Rigorous examination of how evidence was gathered, including search and seizure issues, wiretap or surveillance authorizations, and the reliability of cooperating witnesses.

Suppression and pretrial motions. Where evidence was obtained improperly or procedural safeguards were skipped, pretrial motions can reshape the government's case substantially before trial.

Negotiation posture backed by trial readiness. Federal prosecutors calculate risk carefully. A defense visibly prepared to litigate, including contesting guideline calculations and challenging the government's evidence, changes the posture of every negotiation, including any plea discussion.

Why Early Counsel Matters

The period before an indictment is often the highest-leverage phase of a federal case. Decisions made in this window, such as how to respond to a subpoena, whether to engage with investigators, and what records to preserve, can determine whether a matter ends in no charges, reduced charges, or a fully contested indictment. Waiting until after charges are filed forfeits much of that leverage. This practice engages federal matters from the earliest possible stage because of how much gets decided before a case ever becomes public.

Why Trial Readiness Matters

Federal prosecutors carry significant resources and high conviction rates, in part because so many federal defendants negotiate from limited leverage. A defense built and prepared as though the case will go to trial changes that calculus. Genuine trial readiness, not just the appearance of it, lets a defense negotiate from strength rather than necessity.

Frequently Asked Questions

I received a target letter. What should I do?

Contact an attorney immediately, before responding to the letter or speaking with investigators. A target letter indicates the investigation is advanced, and how you respond in the following days can materially affect the outcome.

Does a grand jury investigation mean I will be charged?

Not necessarily. A grand jury investigation means prosecutors are gathering evidence to determine whether probable cause exists. Strategic engagement during this stage can, in some cases, influence whether an indictment is ultimately sought.

How are federal cases different from state cases?

Federal cases generally involve different agencies, procedural rules, sentencing frameworks (including the U.S. Sentencing Guidelines), and often greater investigative resources than state cases. The strategic considerations differ accordingly.

Do you handle federal cases outside of Texas?

What should I do if federal agents want to speak with me?

In general, it is advisable to decline to answer questions and to request an attorney before any conversation with federal agents, regardless of how routine or informal the contact seems.
