Dubuque Criminal Defense Attorney

Aggressive, Experienced & Strategic Representation

If you are facing a law enforcement investigation into criminal activity or have been arrested for a crime, you are likely in a state of understandable stress. Your future and the future of those who depend on you may be at risk. Under these trying circumstances, it is paramount that you exercise the rights granted you under the Constitution. You have the right to an attorney and to a fair and speedy trial. Your right to an attorney at this early stage is vital. What you say and do can have a negative impact on your case when you don’t understand criminal law and how law enforcement will work against you in pursuit of charges. Furthermore, an attorney may be able to intervene early with knowledge and understanding that can lead to no charges being filed in the first place.

The above are just two scenarios of how the advocacy of a strong and proven defender can benefit you from the inception of your case throughout all stages to its resolution. At Pioneer Criminal Defense, you can work with a highly-experienced and aggressive Dubuque criminal defense and OWI lawyer whose only goal is to help you obtain the best possible case result based on the facts and circumstances of your situation. That may sound simple but it is a premise based on hard work, dedication, extensive knowledge of the criminal justice system, and strong negotiation and courtroom skills. Those are qualities you will find in abundance at our firm where no case is too big or too small to take on.

20 Years of Experience

Tough Criminal Defense With You in Mind

Our firm is devoted exclusively to criminal defense and OWI which gives you the advantage of our laser focus in this practice area. Attorney Cory Thein is backed by 20 years of experience which includes handling over a thousand cases ranging from domestic violence to drug charges, OWI/DUI, theft crimes, sex crimes, and more. We handle all misdemeanors and felonies at the state level as well as federal charges. Our attorney has the background and qualifications you need for all aspects of criminal defense representation from making independent investigations of your arrest and charges, analyzing evidence in search of weaknesses, negotiating with prosecutors for reduced charges or sentencing, to presenting aggressive arguments before a judge and jury.

In some cases with certain circumstances, we charge a flat $1,750 fee to represent you for OWIs and some other criminal defense matters. In others, your fees will be dependent on the specifics of the matter. However, in all cases, our concentration is on you as a client and pursuing what is in your best interests. Every case is different, based on unique facts, history, and legal goals. This means that we tailor our representation to the individual we serve.

In all criminal charges, you are fighting back in a tough and complicated criminal justice system that can make you feel alone, vulnerable, and with little chance of a positive outcome. However, that is not the case when you have an equally tough and tenacious advocate in your corner who has a thorough understanding in how to deconstruct evidence, build a defense strategy, and follow through with strong skills at the negotiation table or in court. Pioneer Criminal Defense is here to help you lessen or avoid the harsh penalties connected with criminal convictions. Let us defend your rights and use our extensive experience in seeking a favorable outcome at this critical period in your life.
