Oberheiden, P.C. is a federal law defense law firm providing its client services across the nation. With a team of experienced criminal defense attorneys and former federal prosecutors, our attorneys have collectively handled thousands of federal cases. We take a strategic and aggressive approach that is designed to secure a favorable resolution for our clients as quickly as possible, and we rely on notable experience inside of the U.S. Department of Justice (DOJ) to combat the government’s accusations.

Are You Under Investigation or Facing Charges?

If you have been contacted by federal agents, if you have received a target letter or grand jury subpoena, or if you are concerned that some sequence of events may have made you a target for federal investigation – you need experienced legal representation from our dedicated Philadelphia federal criminal defense lawyers. Federal criminal investigations can move quickly; and once you find out that you are a target, investigators and prosecutors will have likely already formed an opinion about your guilt for the crime (or crimes) alleged.

If you have been arrested in Philadelphia, or anywhere in Pennsylvania, it is imperative that you speak with a federal criminal defense attorney as soon as possible. You need to be prepared for the process to come, and you need to make sure you avoid mistakes that could jeopardize your defense. Most federal crimes carry severe penalties, and you could be facing insurmountable financial liability in addition to years, if not decades, of federal incarceration.

Federal authorities are aggressively pursuing a broad range of criminal investigations in the Philadelphia area. Raids, arrests, and indictments are all routine occurrences, with everyone from alleged drug dealers to corporate healthcare CEOs facing the risk of prosecution. Our attorneys will work hard to protect you, but you need to act fast. To get started with a free and confidential case assessment with a Philadelphia federal defense lawyer, contact us today.

5 Stages of Successful Federal Criminal Defense in Philadelphia

In a federal criminal case, avoiding conviction requires a comprehensive approach that focused on attacking the federal law enforcement agencies’ cases at each stage of the process.  At Oberheiden, P.C., our representation includes:

1. Intervening With the Goal to Prevent Charges from Being Filed

In a federal investigation, early intervention is critical. If you contact us while your investigation is pending, our attorneys can make contact with the prosecutors assigned to your case to discern the scope and nature of the allegations against you. Then our strategy generally includes challenging the assumptions of the federal government, along with their legal interpretations, and investigatory procedures.

2. Identifying All Available Defenses and Executing a Strategic Plan

Once we gain a firm understanding of the theory of the government’s case, we can then begin outlining all of the factual and legal defenses you have available regarding the specific federal criminal offense. This includes not only challenging the government’s evidence (remember, in order to obtain a conviction, the government must prove its case beyond a reasonable doubt), but also raising any affirmative defenses or safe harbors that may insulate you from prosecution on federal charges.

3. Fighting to Secure Bond

If you have been detained, we will work vigorously to secure bond as quickly as possible. While federal bond matters involve unique and challenging processes and procedures, we have close to a 100% success rate securing bond in federal criminal cases.

4. Engaging with Prosecutors to Secure Dismissal Prior to Trial

If it is not possible to resolve your case before a federal criminal charge charge is filed, we will continue to maintain contact with the prosecutor’s office in order to work toward a favorable pre-trial resolution. Government attorneys do not want to go to trial if they do not have a case, and we will aggressively assert all available defenses in order to effectuate the goal of persuading the attorneys working on your case that further prosecution is unwarranted.

5. Vigorously Representing Criminal Defendants in Federal Court

Finally, if your best option is to fight for justice at trial, we will meticulously prepare to present a comprehensive defense in court. With experience in hundreds of bench and jury trials, we have experience in what it takes to raise doubt about the government’s case, and we will work vigorously to protect you against the consequences of a conviction.
