Federal Criminal Defense Attorneys in Fairfax, Virginia

Being investigated or charged with a federal crime is one of the most serious legal challenges you can face. Federal prosecutions are handled by well-resourced agencies like the FBI, DEA, IRS, DHS, HIS, and ATF, and the penalties can be far more severe than in state court. If your freedom, finances, and future are on the line, you need an experienced legal team that knows how to go toe-to-toe with the federal government.

At Crowley Peritz Law, we provide high-level defense for clients facing federal charges throughout Fairfax, Northern Virginia, and the Eastern District of Virginia. With more than 30 years of combined experience focused exclusively on criminal law, we bring insight, strategy, and personal commitment to every case. In addition to serious felony cases, we also represent clients charged with federal misdemeanors such as DWI on federal property, reckless driving, and unlawful entry, often stemming from incidents on military bases, national parks, and federal buildings like the Pentagon or the Smithsonian.

Why Federal Charges Demand a Skilled Defense

Federal crimes carry long prison sentences, heavy fines, and collateral consequences that can follow you for life, including loss of employment, professional licenses, and immigration status. Unlike many state-level charges, federal investigations often involve:

  • Extensive Surveillance and Grand Jury Proceedings
  • Sealed Indictments and Multi-Agency Task Forces
  • Complex Sentencing Guidelines and Mandatory Minimums
  • Strict Procedural Rules and Evidentiary Standards

If you’re under investigation or have been indicted, hiring an attorney who handles only criminal defense and has specific experience in federal court is critical.

Why Choose Crowley Peritz Law for Federal Defense?

There’s no shortage of criminal defense attorneys in Northern Virginia, but few offer the experience, courtroom reputation, and personalized support that Crowley Peritz Law delivers. Here’s what sets us apart:

The Importance of Early Legal Intervention

Federal investigations are often months or years in the making before charges are filed. If you’ve received a target letter, grand jury subpoena, or visit from federal agents, it’s critical to speak to a lawyer immediately.

Early legal intervention allows us to:

  • Protect your Fifth Amendment rights
  • Avoid unintentional self-incrimination
  • Communicate with prosecutors on your behalf
  • Build a proactive strategy to challenge or limit charges

We can sometimes intervene before formal charges are filed, influencing how prosecutors approach the case or negotiating a resolution that avoids indictment altogether.

Serving Fairfax and the Northern Virginia Region

We are proud to represent clients across Fairfax and surrounding areas, including:

  • Alexandria
  • Arlington
  • Loudoun County
  • Prince William County
  • Stafford County
  • Winchester

We primarily defend clients in the U.S. District Court for the Eastern District of Virginia, Alexandria Division. While we have taken cases in the Richmond Division and the Western District of Virginia, or even federal court in Washington, D.C., we typically do so only if the case justifies the additional cost and complexity, often partnering with local counsel when appropriate.
