Do you need a lawyer that dedicates his entire practice to federal criminal defense and who offers the experience of hundreds of federal cases?

“I don’t know what I would have done without him…” If you find yourself in a situation of concern, know that there is no such thing as a hopeless case. Dr. Nick Oberheiden has turned around many cases and avoided jail time, criminal charges, and public humiliation for business clients, entrepreneurs, physicians, nurses, lawyers, current prosecutors, public officials, many other good citizens.

  • (1) FBI, OIG, DEA, IRS Investigations. Call Nick today and find out how he would approach your case and what results he obtained for others in similar cases. Nick has handled a plethora of federal cases involving all major law enforcement agencies such as the FBI, the DEA, the Office of Inspector General, and many others. Why wait and defend when you can intervene and resolve? The earlier clients contact Nick in an investigation, the higher the chances Nick can convince the government not to continue the case building against you. Nick routinely presents his clients’ cases at the FBI, the U.S. Attorney’s Offices and at the Department of Justice, and he uses these opportunities to clarify facts and to make compelling arguments why his client should not be charged. Unlike most classic criminal defense attorneys, Nick does not wait for an event to occur to then defend it; instead Nick uses a heavy proactive approach and immediately enters a case resolution dialogue with the government.
  • (2) Grand Jury Investigations. Just last month alone, Nick represented several East Coast clients in high-stakes federal grand jury proceedings in different federal districts involving the Department of Justice, the Department of Defense, the FBI, the DEA, the IRS, and the Department of Health and Human Services. Although each client was considered “culpable” and “complicit,” Nick turned their cases around and Nick convinced prosecutor by prosecutor to not charge his client in these unrelated matters. If your business receives a grand jury subpoena from the U.S. Attorney’s Office in Chicago (219 S. Dearborn St., Chicago, Illinois 60604), you need to understand that you are potentially steps away from an indictment. Any mistake in your reaction or response to this subpoena can have a real life impact. Don’t gamble when it comes to a grand jury subpoena. Call 866-Hire-Nick to speak to Nick immediately and directly and obtain the advice needed to stay out of trouble.
  • (3) Case Dismissals & Probation. Some cases inevitably end up with courts and, when that is the case, you need to have lawyers by your side, who understand how the federal court system works. Here are a few recent examples. Extremely rare, Nick and his team have convinced a federal court to dismiss the fraud allegations against their client while all other defendants remained charged. Similarly, Nick obtained probation in a health care fraud case even though the federal sentencing guidelines suggested years of incarceration. Nick also achieved probation in a complex federal computer crime case when, again, the federal sentencing guidelines recommended several years of imprisonment.

Remember: Federal cases are not the same as a DUI offense. If the Department of Justice and the FBI is investigating you, you just don’t have the luxury of making wrong choices when it comes to selecting the right attorney. Nick is not a DUI defense attorney and he is the wrong lawyer to call for shoplifting. However, when the United States government, the Department of Justice, the U.S. Attorney’s Office, the FBI, the IRS, the DEA, or the OIG-HHS agencies are after you, you should strongly consider Nick’s federal experience to avoid jail or to get the case dismissed.

10 Important Questions Regarding Federal Criminal Defense in Chicago, Illinois

The Northern District of Illinois, which covers Chicago, Cook County, Will County, Dupage County, Lake County, Grundy County, Kendall County, Kane County, LaSalle County, McHenry County, DeKalb County, Boone County, Winnebago County, Stephenson County, Jo Davies County, Carroll County, Ogle County, Lee County, and Whiteside County, is known for its rigid enforcement of federal laws. Federal prosecutors in Chicago and Rockford, Illinois, are among the most trained and focused government attorneys and they are known for combatting federal fraud, federal financial crimes, computer offenses, and white-collar crimes. The following are among the questions clients from Chicago ask attorney Dr. Nick Oberheiden the most.

Q: What Is a Federal Conspiracy?

Among the most common federal charges in Chicago are so-called federal conspiracies. When this happens, the government essentially tries to glue together various defendants who don’t need to know each other and often have never heard of each other—in an effort to show that each of the co-defendants added something to the overall success of the alleged conspiracy scheme. For example, in a health care fraud conspiracy involving home health, the government may charge the business owner, staff members, and various referring physicians even when the physician defendant never had any interaction with the other physician defendants. Examples:

  • Conspiracy to Commit Medicare Fraud (18 U.S.C. 1347; 18 U.S.C. 371)

  • Conspiracy to Accept or Receive Illegal Kickbacks (42 U.S.C. 1320a-7(b)(b); 18 U.S.C. 371)

  • Conspiracy to Commit Obstruction of Justice (18 U.S.C. 1518, 1519; 18 U.S.C. 371)

  • Conspiracy to Commit Aggravated Identity Theft (18 U.S.C. 1028A; 18 U.S.C. 371)

  • Conspiracy to Make False Statements Relating to Health Care Matters (18 U.S.C. 1035; 18 U.S.C. 371)

  • Conspiracy to Distribute Controlled Substances (21 U.S.C. 841; 21 U.S.C. 846)

  • Conspiracy to Commit Health Care Fraud (18 U.S.C. 1347; 18 U.S.C. 371)

  • Conspiracy to Commit Theft or Embezzlement in Connection with Health Care (18 U.S.C. 669; 18 U.S.C. 371)

  • Attempt or Conspiracy to Commit Health Care Fraud (18 U.S.C. 1349; 18 U.S.C. 371)

  • Conspiracy to Commit Medicaid Fraud (18 U.S.C. 1347; 18 U.S.C. 371)

  • Conspiracy to Commit Securities Fraud (18 U.S.C. 1348; 18 U.S.C. 371)

  • Conspiracy to Unlawfully Use Health Information (42 U.S.C. 1320d-6; 18 U.S.C. 371)

  • Conspiracy to Use Identification Information (18 U.S.C. 1028(a)(7); 18 U.S.C. 371)

  • Conspiracy to Commit Bribery (18 U.S.C. 201; 18 U.S.C. 371)

  • Conspiracy to Commit Mail Fraud (18 U.S.C. 1341; 18 U.S.C. 371)

  • Conspiracy to Commit Wire Fraud (18 U.S.C. 1343; 18 U.S.C. 371)

  • Conspiracy to Commit Money Laundering (18 U.S.C. 1357; 18 U.S.C. 371)

  • Conspiracy to Commit Bank Fraud (18 U.S.C. 1344; 18 U.S.C. 371)

  • Conspiracy to Commit Tax Fraud (26 U.S.C. 7206; 18 U.S.C. 371)

Q: What Are Common Health Care Fraud Charges in Chicago, Illinois?

Chicago is one of the few declared epicenters of health care fraud in the United States. Because fraud and abuse in the health care industry in Northern Illinois largely exceeds the national average, the U.S. government created the Medicare Fraud Strike Force in Chicago. The Medicare Fraud Strike Force is a team of federal health care fraud prosecutors and investigators specially tasked and equipped to investigate and prosecute health care fraud in Chicago, Illinois. Anyone in the Chicago health care industry must expect rigorous and aggressive prosecution if the underlying allegations involve Medicare fraud, Medicaid fraud, violations of the Controlled Substances Act, opioid and drug diversion offenses, or violations of the Anti-Kickback Statute.

Q: What Are Chicago DEA Opioid Investigations All About?

Just like the rest of the United States, Chicago has experienced unprecedented waves of DEA search warrants, DEA investigations, and federal arrests alleging criminal violations of the Controlled Substances Act, drug diversion, and prescription fraud. DEA defense attorney Dr. Nick Oberheiden has been on the forefront representing physicians and pharmacies against FBI and DEA investigations—with remarkable success. Not a single one of the pharmacies Nick represented in DEA investigations has been charged with a crime or a violation of the Controlled Substances Act. Because Nick understands the underlying health care rules and regulations, he can tailor his defense to expected compliance levels and show satisfaction of the accepted standards of medicine.[otw_shortcode_content_toggle title="Q: What Are "Financial Crimes?"" opened="closed"]

Chicago is one of the world’s headquarters for economic growth and development. The U.S. Attorney’s Office actively investigates compliance with federal financial obligations, capital distributions, and investor recruitment. Big and small businesses in the Chicago area must be extra compliant to not run afoul of federal program fraud, investment and securities fraud, bank fraud, mortgage fraud, federal embezzlement, tax fraud, mail and wire fraud, money laundering, and health care fraud to name just a few financial crimes.

Q: What Should I Do When Chicago FBI Agents Want to Interview Me?

When FBI agents show up at your house or your business, you cannot volunteer yourself to an interview without first consulting with an experienced federal criminal defense attorney. After all, Chicago FBI agents come to you because they consider you a person of interest in a federal criminal investigation. Whether that means you are a witness, a subject, or a target of the investigation, they will not share with you, but will do so with an attorney. Because everything you disclose to federal law-enforcement must be truthful and complete— any withholding or misrepresentation of the facts can constitute a federal felony by itself—caution and preparation is in order. The right course of action is to confirm your identity and to politely request to visit with an attorney first. Federal criminal defense attorney Dr. Nick Oberheiden will not allow you to blindly testify in front of agents without first knowing the nature of the investigation, the purpose of the interview, and your potential exposure in the case. If agents do show up at your house, call Nick immediately and stop the conversation with the agents.

Q: What Should I Do When I Receive a Grand Jury Subpoena from the U.S. Attorney's Office in Chicago, Illinois?

If you receive a grand jury subpoena from the U.S. Attorney’s office for the Northern District of Illinois that means that you or your business is subject to a federal criminal investigation. Caution is in order. The job of the federal grand jury is to determine against whom to bring federal felony charges. With a grand jury subpoena you are essentially being notified that you are among the candidates the grand jury considers for its case. This is not the time to hesitate and this is not the time to follow advice of inexperienced counsel. Everything you do at this point can have a major impact on the grand jury’s decision to include you or not include you in an upcoming indictment. Nick Oberheiden has a 100% success rate representing individuals and businesses in federal grand jury investigations. Nick knows that mere compliance with the subpoena is never enough. Nick has built a substantial track record throughout the United States by convincing federal prosecutors to discontinue the investigation against his clients. He is available to do the same for you.

Q: What Does It Mean When I Receive a Target Letter from the U.S. Attorney's Office in Chicago, Illinois?

A target letter from the U.S. Attorney’s Office in Chicago is the essential equivalent of a last warning before the government presses charges against you. A target letter informs you that the government believes you have committed a federal offense; however, the letter encourages you and your attorney to discuss the matter with the undersigned federal prosecutor in a last effort to avoid an indictment. It is this invitation that is included at the end of each target letter that allows experienced federal criminal defense attorneys like Dr. Nick Oberheiden to initiate a rapid, comprehensive federal criminal defense approach. Nick will immediately enter a dialogue with the United States government and introduce helpful, clarifying and exonerating information to the prosecutor-in-charge to prove his client’s innocence.

Q: How Much Experience Should My Federal Lawyer Have?

The federal criminal justice system does not forgive mistakes. If you are under investigation or formally accused of having committed a federal crime, your life is in danger. Literally. Federal prosecutions are tougher and federal sentences are harsher compared to the state justice system. Just like you would want a specialist surgeon to treat and operate on your spine, the same applies when it comes to selecting an attorney to handle a federal matter. Not every surgeon is a spine surgeon and not every lawyer is a federal criminal defense attorney. You must make sure that you ask specific questions to explore the lawyer’s experience and history before you commit your life into the hands of that lawyer. For example, you should ask what percentage of the lawyers practice is dedicated to federal criminal cases. You should ask how many federal criminal investigations your lawyer has handled and how many of them resulted in no criminal charges. If, for example, your federal matter falls into a specialized category such as health care fraud, you need to ask specific questions such as: how many federal health care fraud cases have you handled and what percentage of your practice is dedicated to health care fraud defense matters? Because you don’t want to be your lawyer’s test case, the answers to your questions must be compelling and convincing and not just good sales talk.

The easiest step in the entire process is to contact Nick. When you call 866-Hire-Nick, your car will connect directly with Nick and no paralegal or secretary will wall you off. Nick will discuss your situation in a free and absolute absolutely confidential conversation.

Q: How Much Does It Cost to Defend My Case?

This question is hard to answer without knowing what your case is about (general criminal defense, specialized area such as health care fraud) and in what stage (pre-indictment, post-indictment etc., upcoming trial etc.) you are in. In general, legal fees in federal criminal cases tend to be divided into stages to enhance predictability.
