If federal authorities are after you, they are not going to stop until they have exhausted every option for convicting you in court. Federal agents and prosecutors from the Department of Justice (DOJ), Federal Bureau of Investigation (FBI), Office of Inspector General (OIG), U.S. Attorney’s Office, and other federal agencies aggressively pursue criminal charges with vast resources at their disposal, and many of them have built their careers on putting away criminals for serious federal offenses.

Florida Federal Criminal Defense AttorneyOberheiden, P.C. is a nationally-renowned federal criminal defense law firm representing clients in Florida. Our attorneys have been featured as guest commentators by media outlets in Florida and nationwide, and several of our attorneys served as government attorneys and prosecutors with the DOJ and the U.S. Attorney’s Office prior to entering private practice. Unlike other firms, we do not employ junior associates or paralegals; so, when you choose our firm to represent you, you will work with our senior attorneys throughout the entire duration of your case.

Cases We Handle

We represent clients facing allegations and charges involving all types of white-collar federal crimes. Our clients include public figures, politicians, licensed professionals, company executives, business owners, and other high-profile and high-net-worth individuals, and we handle cases in the Northern, Southern, and Middle Districts of Florida.


Fraud crimes involve obtaining money or other items of value through false or fraudulent pretenses, false promises, or misrepresentations or omissions of material information. The federal fraud statutes apply to fraud targeting banks, insurance companies, other private corporations, investors, consumers, and the federal government. We represent clients charged with federal fraud crimes including:

Financial Crimes

Financial crimes are a class of federal offenses that involve obtaining through improper means or paying money (or anything else of value) for illegal purposes. At the federal level, white-collar financial crimes include:

Other White-Collar Offenses

In addition to fraud and financial crimes, we represent clients facing a broad range of other federal offenses as well. This ranges from conspiracy and attempt (which can result in long-term imprisonment even if no substantive crime has actually been committed) to drug crimes and terrorist acts. If you are under investigation or facing charges for any of the following types of offenses, we urge you to contact us immediately:

Understanding the Three Stages of Federal Criminal Prosecution

The federal criminal justice process can be broken down into three primary stages. We represent clients at each stage, deploying varying case strategies that are focused on the particular procedural, legal, and factual circumstances involved.

1. Federal Investigation

Most federal cases begin with an investigation. This investigation could last for days, weeks, or months, and it could involve one or multiple federal agencies and task forces. During the investigative stage, our primary goal is to prevent charges from being filed. If you aren’t charged, you can’t be convicted, and this means that you won’t be at risk of going to prison for a very long time.

2. Grand Jury Subpoena

At the federal level, criminal charges are issued through the grand jury process. Federal prosecutors must present their evidence to the grand jury, and the jurors are responsible for deciding whether there is “probable cause” to move forward with a criminal case. Executing a defense during the grand jury process is unique in many respects, and our Florida federal criminal defense attorneys have successfully defended numerous clients resulting in the termination of the case without charges being filed.

3. Criminal Trial

If you get indicted by a federal grand jury, then your case will be set for trial. However, this does not necessarily mean that you will need to fight for your freedom in court. While we have an extensive federal trial record, our federal defense attorneys have also succeeded in getting indictments dismissed prior to trial and negotiating plea deals that have protected our clients from prison.

What to Do After a Federal Arrest in Florida: Dos and Don’ts

When facing federal criminal charges in Florida, there are both key steps you need to take and critical mistakes you need to avoid. If you are under investigation or facing charges:

DO: Speak with a Florida Federal Defense Attorney Immediately

If you have had any contact with federal agents in regard to a possible investigation, you need to speak with a defense attorney immediately. If you get arrested, the only thing you should say to anyone is that you are requesting to speak with your attorney.

DON’T: Give a Statement or Answer Any Questions

Regardless of how innocent or guilty you think you are, you should not give a statement or answer any questions without your federal criminal defense attorney present. Federal agents are experts at interrogation, and anything you say will only be used against you.

DO: Protect Your Constitutional Rights

As the target of a federal criminal investigation or a defendant in the federal criminal justice system, you are entitled to the protections afforded by the U.S. Constitution. This includes the protections against unreasonable searches and seizures, the protection against self-incrimination, and the right to legal representation. If you believe that federal agents have violated these rights in any way, this is something you will absolutely want to discuss with your attorney, as it may mean that the government’s evidence is inadmissible in court.

DON’T: Cooperate with Federal Agents in Any Way

Unless otherwise advised by your federal defense attorneys, you should not cooperate with federal agents in any way. Be polite and do not resist arrest, but also make absolutely certain that you are not unnecessarily increasing your risk of prosecution.

DO: Start Working on Your Defense Right Away

By the time you find out that you are being targeted, the government is already several steps ahead of you. To level the playing field, you need to begin working on your defense right away.

DON’T: Ruin Your Chances of Asserting a Successful Defense

Speaking to federal agents, posting on social media, engaging in criminal conduct, missing court dates, and other mistakes can ruin your chances of asserting a successful defense. Our Florida federal criminal defense lawyer can help you avoid these mistakes while negotiating with the authorities on your behalf.

Frequently Asked Questions Answered by a Florida Federal Criminal Defense Attorney

What should I do if federal agents show up at my house?


If federal law enforcement agents with the FBI, IRS, OIG or DEA show up at your home or business, it means that you are either under investigation for a federal crime or you have the knowledge they believe is relevant to their investigation. Even if you are innocent and believe that you are not under investigation, that is not a guarantee that agents won’t find something that triggers a more in-depth investigation. To protect your interests, it is imperative that you reach out to a dedicated Florida federal criminal defense attorney as soon as possible.

What is a grand jury subpoena?


A grand jury subpoena is a court order requiring you to participate in an open criminal investigation. Grand jury subpoenas are issued by the Department of Justice, most often by the U.S. Attorney’s Office. When a U.S. Attorney issues a grand jury subpoena, they will either demand you produce the specific evidence or testify at a grand jury proceeding. If you are called to testify in front of the grand jury, it may be because the federal government believes you are involved in the crime. However, you are not entitled to have an attorney present when you testify. If you received a grand jury subpoena, it is crucial that you reach out to a respected Florida federal criminal defense attorney to discuss the best way to respond.

What should I do if I’m indicted?


If you recently found out that you were indicted on federal criminal charges, you have a lot on the line. What’s worse, the federal prosecutors assigned to your case have already compiled a case against you and presented it to a grand jury, which found that there was probable cause to believe you committed the offenses in question. Given this reality, the first thing you should do after you find out you are indicted is to secure the assistance of a Florida federal criminal defense attorney. Your attorney can help you understand the nature of the government’s allegations and work with you to develop a compelling defense to the charges.

When should I contact a Florida federal criminal defense attorney?


As soon as possible. Federal prosecutors already have an advantage in that they get the opportunity to conduct an in-depth investigation without your knowledge. In most cases, by the time you learn that you are facing federal charges, the federal prosecutor assigned to the case will have already presented their case to a grand jury, which found probable cause to believe you committed the offenses in question. However, this doesn’t mean that there isn’t hope for a successful resolution. Whether you currently face federal charges or believe you are under investigation, a respected Florida federal criminal defense attorney can advise you of your options, what is at stake, and how best to proceed.

Should I try to negotiate a plea agreement or take the case to trial?


Negotiating with federal prosecutors is the best option in some cases, but certainly not in every case. And engaging in negotiations without a seasoned Florida federal criminal defense attorney by your side will not likely yield the results you are looking for. While acceptance of responsibility is one reason why prosecutors may offer a favorable plea agreement, there are many others that you may not be prepared to address. For example, an experienced Florida federal criminal defense attorney can point out potential weaknesses in the government’s case, possibly leading to withdrawn charges. If you face charges in federal court, or believe you are under investigation for a federal crime, contact a Florida federal criminal defense attorney as soon as possible.

What is at stake in a federal prosecution?


A conviction for a federal crime can carry punishments that will make your head spin. Jail time, fines, professional sanctions, and probation are all on the table. However, the federal sentencing rules are extremely complex and both federal judges and prosecutors lack the discretion that most of their state counterparts enjoy. That said, just because you were charged with a federal crime does not mean you are guilty. In fact, you are presumed innocent unless and until the government can prove you guilty beyond a reasonable doubt. If you are facing serious federal charges, your first step should be to reach out to a Florida federal criminal defense attorney to have them review your case and provide you with their thoughts. From there, you can better determine your best course of action.
