You Have Rights

Remember, you are innocent unless PROVEN guilty, and the burden of proving your guilt rests entirely upon the government. Further, keep in mind that it may be possible to reduce some of the charges against you to a less severe offense or to otherwise negotiate an alternative resolution to your case prior to trial. A criminal offense in Illinois should be taken seriously. If convicted, it may have adverse effects in your life, such as:

  • This crime may show up on a criminal background check
  • Possible loss of your current employment and your reputation
  • Being subject to hefty fines, potential time in jail and hours of community service
  • The potential of being passed over or denied acceptance by future schools, employers and other organizations that review criminal backgrounds

An Attorney And Army Veteran

As a criminal defense attorney and Army veteran, I have personally handled nearly every criminal case imaginable. I know the strategies used by prosecutors and, more importantly, I know how to defend against them. When looking for a lawyer, you need aggressive and experienced counsel to successfully defend your rights.

Prior to staring my firm, I worked for a nationally recognized private criminal defense and DUI attorney. During that time, I represented hundreds upon hundreds of individuals facing the criminal justice system, license suspensions, jail, etc. All my courtroom experience comes from private practice – I’ve had to earn my client’s trust and respect. I’ve NEVER worked for the government.
