Santa Ana Federal Criminal Defense (FBI, OIG, IRS, DEA)

Trusted Santa Ana Federal Criminal Defense Lawyers

Centrally located in Orange County, Santa Ana is also at the center of a significant number of federal criminal investigations. If you live or work in Santa Ana and you are being targeted for prosecution by the FBI, OIG, IRS, or DEA, you need to speak with our experienced Santa Ana federal criminal defense lawyers immediately.

Health care providers, business owners, company executives, and other individuals in Santa Ana, CA, are at risk for being targeted in federal criminal investigations. Federal agencies, including the Federal Bureau of Investigation (FBI), Office of Inspector General (OIG), Internal Revenue Service (IRS), and Drug Enforcement Administration (DEA), are increasingly targeting legitimate businesses and licensed professionals. And in many (if not most) cases, these investigations come as a complete surprise.

If you have just discovered that you are under investigation by the FBI, OIG, IRS, or DEA in Santa Ana, it is critical that you speak with a defense attorney immediately. In order to avoid prosecution, you need to defend yourself. And the best way to do this is to stop the government in its tracks.

At Oberheiden, P.C., our Santa Ana federal criminal defense attorneys provide aggressive and strategic representation for defense of federal criminal allegations in Santa Ana, throughout California, and nationwide. Our federal criminal defense team is comprised entirely of senior attorneys, and our team approach affords each client the full benefit of our attorneys’ centuries of combined legal experience. Additionally, since many of our attorneys served long stints with the U.S. Department of Justice (DOJ) prior to entering private practice, we have unique insights into the defense strategies that work to resolve federal investigations without criminal charges being filed.

A National Federal Criminal Defense Law Firm Serving Santa Ana, CA

When we represent clients in federal criminal matters, our first priority is to intervene in the government’s investigation. This prevents federal agents and prosecutors from continuing to pursue you unchecked, and it lets them know that you intend to aggressively defend yourself rather than waiting to take your chances at trial. By taking an aggressive stance, our proven Santa Ana federal criminal defense lawyers are often able to resolve our clients’ cases prior to indictment. And if you aren’t indicted, this means that you can quickly get back to business as usual.

Our aggressive approach to defending physicians, pharmacists, executives, and other clients during federal criminal investigations includes:

  • Making Immediate Contact with the Investigating Agency (or Agencies) – As soon as possible after you engage our firm to represent you, we will make contact with the agency (or agencies) handling your investigation to let them know that you are now represented by legal counsel. Our Santa Ana federal criminal defense attorneys will determine the status of the investigation, and we will gather the information required in order to determine the nature of the government’s interest in your business or practice.
  • Executing a Strategy for Terminating the Investigation without Charges – What triggered the investigation? What steps have the special agents and prosecutors handling the investigation taken to date? How close are they to filing charges? What issues have they overlooked? These are just some of the questions that we will address in order to develop and execute a strategy designed to prevent you from facing criminal charges.
  • Preparing for the Possibility of an Indictment and Trial – While we focus our efforts on securing a pre-indictment resolution, this strategy actually involves preparing for the possibility that you could face criminal charges at trial. Why? By letting the prosecutors handling your case know that we are fully prepared to litigate if necessary, our skilled Santa Ana federal criminal defense lawyers can secure additional leverage for pre-indictment negotiations.
  • Working Closely with Our Clients One-on-One – In order to provide you with a comprehensive and custom-tailored defense, we need to learn as much about the investigation and your business or practice as possible. To do this, we will work closely with you one-on-one. This is true not only during the initial stages of our representation, but also on an ongoing basis as we continue to refine and redirect our case strategy based upon the circumstances at hand.
  • Never, Never Resigning Our Clients’ Fate – When you engage our federal criminal defense team to represent you, we will fight for you until the bitter end. We refuse to accept that our options are limited, and highly experienced Santa Ana federal criminal defense attorneys do not back down regardless of how much pressure federal prosecutors attempt to exert on our clients.

Common Allegations in FBI, OIG, IRS, and DEA Investigations

Determining why you are under investigation is one of the first steps toward building an effective defense strategy, and this is often much more difficult than it sounds. But, the agency (or agencies) involved in your investigation can tell you a lot about the charges you could be facing if your case proceeds to a grand jury. For example:

If You Are under Investigation by the FBI…

As the nation’s chief law enforcement agency, the Federal Bureau of Investigation (FBI) is responsible for investigating a broad range of federal offenses. If FBI agents have come knocking at your door, you could be under investigation for health care fraud, corporate fraud, computer and internet crimes, public corruption, or any of a variety of other white-collar offenses.

If You Are under Investigation by the OIG…

The Office of Inspector General (OIG) is much more limited in its jurisdiction. Tasked with “protect[ing] the integrity of [health care benefit] programs as well as the health and welfare of program beneficiaries,” the OIG primarily focuses on investigating health care providers and related entities suspected of Medicare and Medicaid fraud.

If You Are under Investigation by the IRS…

The Internal Revenue Service (IRS) focuses its efforts on enforcing taxpayers’ obligations under the Internal Revenue Code. If you have been contacted by agents from the IRS’s criminal enforcement division, this means that you are suspected of tax evasion or other criminal tax violations.

If You Are under Investigation by the DEA…

The Drug Enforcement Administration’s (DEA) focus is somewhat limited as well. The DEA is responsible for enforcing the nation’s drug laws, including the provisions of the Controlled Substances Act that apply to health care providers who prescribe and dispense controlled-substance medications.

FAQs: Defending against Federal Criminal Charges in California

Q: If I know I am guilty, should I cooperate with the government in order to receive a better deal?



First and foremost, you should never assume that you are guilty of a federal crime. You are not guilty until the DOJ proves your guilt beyond a reasonable doubt in U.S. District Court, and there are a variety of defense strategies you can use to prevent this.


Second, while you need to be very careful to avoid violating the terms of any subpoenas you may receive, you need to be equally careful to avoid being overly “helpful” to the agents and prosecutors involved in your case. Remember, they are there to try to put you in federal prison. And if you are guilty, no amount of “helpfulness” is going to prevent them from pursuing charges.

Q: What are some of the defense strategies you can use to protect me?



The answer to this question depends on the specific facts and circumstances involved in your case. Generally speaking, however, some of the defense strategies we most commonly use at Oberheiden, P.C., include:



  • Asserting our clients’ constitutional rights in order to have evidence suppressed from trial

  • Asserting affirmative defenses, such as the safe harbor protections under the Anti-Kickback Statute

  • Challenging the credibility of the government’s witnesses

  • Challenging the government’s evidence of intent

  • Raising doubt about each and every element the government must prove in order to secure a conviction


Q: Can Oberheiden, P.C., represent me in the U.S. District Court for the Southern District of California?



If your best option is to present a defense strategy at trial, yes, we can represent you in the U.S. District Court for the Southern District of California. We maintain a national federal criminal defense practice, and our Santa Ana federal criminal defense lawyers have defended clients in federal district courts across the country. But, keep in mind, in most circumstances, you should be focused on resolving your case before charges get filed.
