About Oberheiden, P.C. – Your Phoenix Federal Defense Attorneys

Oberheiden, P.C. represents Arizona businesses and individuals against target letters and other federal investigations, grand jury subpoenas, and federal healthcare fraud charges. Consisting of multiple former federal prosecutors, our Phoenix federal criminal defense attorneys offer our clients a wealth of government attorney experience. Indeed, some of our Phoenix federal criminal lawyers held leadership positions within the federal government (including the Department of Justice) prior to joining the Firm.

With this experience behind them, our former government attorneys are well-positioned to focus their combined prosecutorial experience on your behalf. In short, our former Department of Justice trial lawyers, Assistant U.S. Attorneys, and former prosecutors will only entertain one goal: to protect you and your rights.

At Oberheiden, P.C., our clients’ cases are handled by our experienced federal law defense litigators themselves — we do not hire associates or junior lawyers because nothing replaces experience. When your freedom may be on the line, we know that there is no time to experiment. Our Phoenix federal criminal defense attorneys include Nick Oberheiden. Nick has successfully represented business executives, public officials, business owners, physicians, lawyers, and many more in prosecutions involving healthcare fraud charges, federal conspiracy charges, internet crimes, and other federal offenses.

Due to the complexity of the federal criminal justice system, the biggest mistake a business or individual facing a federal investigation can make is to underestimate the government’s attorneys. For example, you can hire the best state law criminal attorney in town, but that attorney may very well not have the experience to successfully negotiate with government agents or prosecutors.

At Oberheiden, P.C., our Phoenix federal criminal defense attorney knows what immediate actions will serve your interests. If you are facing federal criminal charges or a government investigation, call us right away to confidentially speak to a former federal prosecutor. Our former federal prosecutors have first-hand experience with how a federal government agency builds a case. With your best interests in mind, our federal criminal attorneys who have extensive experience in the federal court system know how to best respond to the government.

Fighting or Avoiding Federal Charges in Phoenix, Tucson, and Throughout Arizona

Although each case is unique, we approach every case with the same goal — to represent your interests as early as possible in any investigation or trial preparation by the government. We explore all possible grounds for dismissal prior to trial in federal court. For example:

  • Forestall Charges. Our Firm’s primary goal is to avoid criminal charges; one of the ways we do this is by rapidly implementing sophisticated responses to the government’s allegations. Indeed, for some of our clients, we have been able to successfully lessen their sentences, we have made otherwise criminal cases into civil ones, and in federal investigations, we have forestalled criminal charges.
  • Obtained Bond. Bond considerations in federal cases are very different from bonds in state law matters. For most of our clients, we routinely obtain a bond in federal criminal cases.
  • Defenses. Criminal offenses may be countered by a number of accepted defenses. Also, criminal offenses require evidence of intent. Our firm has defended clients in federal investigations, for example, by proving that alleged misconduct did not occur, did not occur intentionally, or did occur but was justified by a recognized defense.
  • Federal Offenses Handled. Our Phoenix federal criminal defense lawyers have defended clients against most types of federal offenses and criminal conspiracies. These include, but are not limited to,18 U.S.C. 1347 healthcare fraud (Medicare fraud, False Claims Act, Medicaid fraud, violations of the Anti-Kickback Statute or the Controlled Substances Act),18 U.S.C. 924 (possession of a firearm in furtherance of a drug trafficking offense, marijuana),18 U.S.C. 1341 mail and 18 U.S.C. 1343 (wire fraud, public corruption, bribery, tax fraud, tax evasion, securities fraud, insider trading, Ponzi schemes, fraud, mortgage fraud), and 21 U.S.C. 841 (distribution and possession with intent to distribute).

If you are facing a federal criminal charge or any other type of government action, call our Phoenix federal lawyer to speak to a former federal prosecutor for an assessment of your case. The former federal government attorneys at our firm know first-hand how the government builds a case and how to respond with the sole goal of your best interest in mind.

The Crucial Component to Success: We Are Trial Lawyers

Phoenix Federal Criminal Defense Lawyer

Oberheiden, P.C. believes that an assertive trial practice wins the day. As such, we don’t recommend that clients take bad plea deals. Our Phoenix federal criminal attorneys diligently analyze all elements of the case while aggressively negotiating with the government. In all cases, we approach the government with the idea of taking the case to court. We do not allow our clients to be easy prey for the government. What our Firm stands for is that you benefit from our attorneys’ government experience and that you win.

Why Choose Oberheiden, P.C.?

1. Our Firm’s Focus on Federal Cases, Law and Trials

Many federal criminal lawyers will take on most types of cases that come in the door. We don’t do this. Our Firm does not dilute our federal law skills set; indeed, we only take — and we limit our practice to — federal law cases. We focus on federal jurisdiction cases for a simple reason. Because the federal and state criminal justice systems are significantly different. We know that to be successful in the federal justice system requires an exclusive focus. Because we only do federal cases, we routinely negotiate with attorneys and agents from the Department of Health and Human Services (HHS), the Office of Inspector General (OIG), the Federal Bureau of Investigation (FBI), the U.S. Attorney’s Office (USAO), the Department of Defense (DOD), the Department of Justice (DOJ), the Department of Homeland Security (DHS), the Drug Enforcement Administration (DEA), and the Internal Revenue Service (IRS)among other federal agencies. Our clients benefit from our attorney’s federal government experience and the thousands of federal matters that we have handled.

2. Our Results

Each potential client should understand that each case is different and the results we have achieved for our clients cannot guarantee a similar outcome in your case. Nonetheless, we have avoided federal criminal charges for a significant number of Firm clients across the nation. Our goal is to turn criminal cases into civil fines and to transform targets of federal investigations into witnesses. Thanks to their government work experience, our Phoenix federal defense lawyers can effectively negotiate on your behalf and argue your case in federal courtrooms.

3. Our Team

At Oberheiden, P.C. your case gets handled by senior experienced attorneys and not handed off to associates or junior lawyers. Our senior attorneys have strong academic and government attorney backgrounds. In all cases, our firm embraces a team approach. This means that through a team effort, our Phoenix federal defense attorneys focus on the best defense strategy.

Oberheiden, P.C.’s former federal prosecutors and federal criminal law defense attorneys are available to discuss your case. Call us and find out how experienced former prosecutors and federal defense attorneys assess your case’s facts and what strategies can be used to protect your freedom, your reputation, or your license. Calls are free and confidential.

FAQs: Federal Prosecutions Questions Relevant to Phoenix, Tucson and Arizona

Q: What is a target letter?

When the prosecutors at the Department of Justice believe that someone either committed a federal crime or has information relevant to their investigation of a federal crime, they will send that person a target letter. Thus, if you received a target letter, it means federal law enforcement believes you are—on some level—involved in a federal crime. How you respond to a target letter can have a major impact on the course of the investigation; thus, it is crucial anyone who receives a target letter immediately reaches out to a Phoenix federal criminal defense attorney.

Q: When should I hire an attorney?

You should retain an attorney as soon as possible after you learn of any federal government action related to you. An assertive legal defense strategy implemented as early as possible is an effective strategy. Your federal criminal defense lawyer should have only one goal, to address and stop government action. Every moment wasted gives the government an advantage and further time to investigate you, your practice, your business, and, of course, your family as well as your affiliates. If you want to discuss your situation with us, please speak to one of our senior attorneys today. Your call and case assessment are free and absolutely confidential.

Q: Which attorney will handle my case?

Our Firm’s clients are represented by experienced senior federal criminal defense attorneys and former federal prosecutors. We focus on your case and will not waste valuable time handing off your case to junior lawyers — our firm does not use them; from the moment you hire Oberheiden, P.C., you will be speaking directly with senior attorneys.

Q: What is your track record?

Our senior and experienced Phoenix federal criminal attorneys have successfully resolved government investigations and prosecutions involving, among many others, healthcare fraud attorney, money laundering, public corruption, wire and mail fraud, and securities fraud. Potential clients should take note that all cases are different and our prior results for other clients do not guarantee a similar outcome in your case.
