Federal convictions carry mandatory minimum sentences, substantial fines, and long periods of supervised release: penalties rarely seen in state court outcomes. The moment federal investigators make contact, or you learn that a grand jury may be reviewing your case, is the moment you need experienced legal counsel by your side.
Whalen Law Office has spent more than 28 years defending clients against federal and state criminal charges across Texas and throughout the United States. With offices in Frisco, Sherman, and Tyler and a practice that regularly takes attorneys to federal courthouses across the country, our team appears before the U.S. District Court for the Eastern District of Texas, where Lewisville-area federal cases are heard. We bring the depth of a dedicated criminal defense practice, the focused attention of a firm that knows each client personally, and a record of more than 2,500 criminal and juvenile charges resolved.
Lewisville is located primarily in Denton County, and while it has its own active state criminal courts, federal charges follow a different path to a different venue with different rules. Clients come to us from Lewisville and the surrounding communities — including Flower Mound, Carrollton, Denton, and Highland Village — facing everything from drug trafficking allegations to complex white-collar investigations. Whatever federal charge you are confronting, our attorneys are available to review your situation and begin building a defense strategy immediately.
Federal vs. State Criminal Charges: Why the Distinction Matters
Not every criminal charge follows the same legal path. State charges are prosecuted by county or district attorneys under Texas law and are handled in state court. Federal charges are brought by a United States Attorney or an Assistant United States Attorney (AUSA) and are prosecuted in U.S. District Court under federal statutes. The difference is not merely procedural. Federal prosecution typically means more investigative resources on the government’s side — often involving the FBI, DEA, IRS Criminal Investigation, Homeland Security Investigations (HSI), or ATF — stricter sentencing frameworks, and significantly longer potential prison terms.
A crime crosses into federal jurisdiction when it involves federal property or federal employees, spans multiple states, is defined by a federal statute (such as drug trafficking, wire fraud, or federal firearms violations), or is investigated by a federal agency. Federal conspiracy charges are particularly common: prosecutors frequently add conspiracy counts to multiply charge exposure and pressure plea agreements. A defendant who may have played a limited role in an alleged scheme can face the same statutory penalties as the central figures simply by virtue of the conspiracy allegation.
Understanding this distinction early is critical. If you have been contacted by a federal agent, received a target letter from a U.S. Attorney’s office, or learned that a grand jury has been convened related to your activities, you are no longer dealing with a local matter. Retaining a federal criminal defense lawyer with Eastern District of Texas experience at this stage, before charges are formally filed, can meaningfully influence how your case unfolds.
Federal Cases We Handle in Lewisville
Whalen Law Office defends individuals and businesses facing the full range of federal criminal charges. Federal criminal law is broad, and the types of cases pursued by the U.S. Attorney’s office in the Eastern District of Texas include the following categories.
Drug Offenses. Federal drug trafficking charges are among the most serious cases in the federal system. DEA and HSI investigations often span years before charges are filed, and mandatory minimum sentences for trafficking convictions can run from five years to life depending on drug quantity and prior criminal history. Drug conspiracy allegations are frequently added to individual possession or distribution charges, extending liability to everyone who allegedly agreed to participate in the scheme.
White-Collar and Financial Crimes. Federal prosecutors aggressively pursue white-collar criminal matters, including wire fraud and mail fraud, healthcare fraud, tax evasion, bank fraud, mortgage fraud, money laundering, embezzlement, and securities fraud. IRS Criminal Investigation handles tax fraud matters, while multi-agency task forces often lead money laundering and bank fraud prosecutions.
Firearms Offenses. Federal firearms charges under ATF jurisdiction carry their own mandatory sentencing enhancements. Prohibited persons in possession of firearms, straw purchases, and trafficking of weapons across state lines are prosecuted federally and carry serious prison exposure.
RICO and Organized Crime. RICO charges, brought under the Racketeer Influenced and Corrupt Organizations Act, are used by federal prosecutors against alleged criminal enterprises ranging from organized crime to fraud rings. RICO cases are exceptionally complex and require defense counsel with experience in multi-defendant, multi-count federal litigation.
Cybercrime. Computer Fraud and Abuse Act cases, identity theft, and federal cybercrime charges are an increasingly common category in the Eastern District. A skilled defense attorney is essential for navigating the technical and legal complexity of these matters.
Other Federal Charges. Whalen Law Office also defends clients against federal criminal conspiracy charges, federal firearms offenses, violent crime allegations, and child pornography charges in federal court.
How Federal Cases Work: From Investigation to Sentencing
Federal criminal cases follow a distinct procedural path that differs significantly from state courts at every stage. Understanding what lies ahead helps clients make informed decisions throughout the process.
Pre-Indictment Investigation. Most federal cases begin long before any charges are filed. Federal agents gather evidence through subpoenas, wiretaps, financial records requests, surveillance, and cooperating witnesses — often for months or years. If you have been contacted by a federal agent, received a grand jury subpoena, or have reason to believe you are the subject of a federal investigation, representation at this stage is critical. An attorney can interact with investigators and prosecutors on your behalf, protect your rights during any questioning, and potentially resolve matters or limit exposure before a formal grand jury indictment is sought.
Grand Jury and Federal Indictment. Federal charges in most cases require a grand jury indictment. A grand jury of 16 to 23 citizens reviews evidence presented by the AUSA and determines whether probable cause exists to formally charge you. This is a one-sided proceeding: the defense has no right to present evidence or cross-examine witnesses. Understanding what the grand jury has reviewed and what charge exposure you face is among the priorities your attorney will address.
Arraignment and Pre-Trial Detention. After a federal indictment, you will be arraigned before a magistrate judge to enter a plea and address conditions of release. Federal prosecutors frequently move to detain defendants pending trial, arguing flight risk or danger to the community. A persuasive argument at the detention hearing can mean the difference between preparing your defense from home or from federal custody.
Plea Negotiations and Trial. The vast majority of federal cases are resolved through a plea agreement negotiated with the AUSA. Your attorney’s ability to challenge the government’s evidence, identify weaknesses in the prosecution’s case, and negotiate charge reductions or cooperation agreements directly shapes the outcome. When cases proceed to trial, you need counsel with genuine federal jury trial experience.
Sentencing. Federal sentencing is governed by the U.S. Sentencing Guidelines and, in many cases, by mandatory minimum statutes. See the section below for a full explanation of how this framework works.
Federal Sentencing Guidelines and Mandatory Minimums
Federal sentences are not left to a judge’s unconstrained discretion. The U.S. Sentencing Guidelines produce a calculated sentencing range based on two primary factors: the offense level, which reflects the type and severity of the crime and specific adjustments such as role in the offense and acceptance of responsibility, and the criminal history category, which reflects the defendant’s prior record. The Guidelines intersection of these two factors produces a range — for example, 51 to 63 months — that the court must calculate and consider, even though judges retain discretion to depart from it with proper justification.
Mandatory minimum sentences apply in drug trafficking cases, firearms offenses, and certain other federal crimes. These floor sentences are set by statute and cannot be reduced by a judge even when the Guidelines would otherwise suggest a lower range. The primary exceptions are substantial assistance motions filed by the government (when a defendant cooperates with prosecutors in a way that aids other investigations) and the federal safety valve, which allows qualifying first-time, non-violent drug offenders to be sentenced below the mandatory minimum.
Defense strategy at sentencing encompasses challenging the offense level calculation, presenting mitigating factors, pursuing downward departure arguments, and, where applicable, building a record for substantial assistance consideration or safety valve eligibility. The difference between effective and ineffective sentencing advocacy can be measured in years.
Federal Courts Serving Lewisville: The Eastern District of Texas
Most of Lewisville is located within the jurisdiction of the U.S. District Court for the Eastern District of Texas. Federal cases originating in Denton County and the surrounding area are typically assigned to the Sherman division of the Eastern District. There are two federal courthouses in Sherman. The Paul Brown United States Courthouse is located at 101 E. Pecan Street. The United States Courthouse Annex is located at 200 N. Travis Street.
Familiarity with the specific courtroom culture, local rules, and judicial preferences of Eastern District judges is a practical advantage in federal litigation. Whalen Law Office attorneys appear regularly in Eastern District courts, and that experience translates to credibility with prosecutors, judges, and court staff at every stage of the proceedings.
Federal criminal appeals from the Eastern District are heard by the U.S. Court of Appeals for the Fifth Circuit in New Orleans. Our team handles federal criminal appeals at the Fifth Circuit level, including cases that were tried by other counsel and where a preserved legal issue warrants appellate review.

Understanding Federal Defense Attorney Fees
Federal criminal defense is a specialized practice, and the cost of representation reflects that specialization. Unlike state misdemeanor or traffic matters, federal cases routinely require months or years of attorney time, review of extensive government discovery, expert witness consultation, and, when cases go to trial, intensive preparation. The total cost of federal representation depends on the complexity of the charges, the projected length of the case, and the experience of the attorney retained.
Attorneys in federal criminal matters typically charge an initial retainer, a deposit against which fees are billed as the case progresses. For federal matters, retainers vary substantially based on case complexity: straightforward cases handled at the plea stage involve different fee structures than multi-defendant trials. Reviewing the retainer agreement carefully and asking clear questions about billing practices upfront are entirely reasonable steps for any client.
Whalen Law Office offers confidential consultations to prospective clients facing federal charges. During a consultation, our attorneys will review the facts of your situation, explain the federal process as it applies to your matter, and give you an honest assessment of your options.

Federal Appeals
A federal conviction is not necessarily the end of the road. The federal appeals process allows defendants to challenge legal errors made at trial, improper jury instructions, sentencing miscalculations, and constitutional violations that affected the outcome. Appeals from Eastern District of Texas cases are filed with the U.S. Court of Appeals for the Fifth Circuit and are governed by strict deadlines and a highly technical briefing process focused on issues that were preserved in the trial record.
