I GET RESULTS. As a US Army veteran, I am here to fight your future. 

I practice exclusively in DUI, traffic and criminal defense. I am one of the few DUI attorneys in Illinois to have been trained in the administration of Standard Field Sobriety Tests - this is the same training the police receive. And I have personally handled hundreds of DUIs - no case is too unique or complicated.

Police contact is one of the most terrifying experiences a human being can go through. Getting through it and saving your sanity, your record, your driver's license, your freedom, are my goals.

Call me now for a FREE discussion of your case on my personal cell. 


You will work directly with me. Prior starting my own firm, I worked under the direction of a nationally-recognized criminal and DUI defense attorney for many years. In law school I clerked for the Homicide Task Force at Cook County Public Defender's Office and the DuPage County Public Defender's. I earned a J.D. from The John Marshall Law School, an M.A. from Purdue University Calumet, and a B.A. from The University of Illinois at Chicago. I also served in the U.S. Army for 4 years and in the National Guard for 6. I am currently a member in good standing of the Illinois State Bar Association, the DuPage Bar Association, the Cook County Bar Association, and the National College for DUI Defense.

Professional, informative and effective
I hired Peter for my 1st DUI which he was able to get me supervision for. Unfortunately, I landed myself a 2nd DUI offense during the supervision period and a felony offense for driving on suspended. Peter got me a deal that amended the felony to a misdemeanor AND the 2nd DUI to Reckless Driving. Really couldn't have asked for much more

First Phone Contact
Well, I actually started my case with a public defender. But as we all know the Pc's job is to try and get the defendant to take a plea. All attorneys in K3 co. run together, so how do I receive a fair trial? Call Attorney O'Connor. Filled out a questionnaire online and within minutes got a call! I'm very impressed with his professional outlook on my case. Made sure I understood everything. I will leave another review as my case continues. Mind you, I'm scared outta my mind. Never had charges like this, but Attorney O'Connor made me feel better after speaking with him. And he didn't try to get thousands of dollars out of my account. Gave me an affordable down payment price. I'm going with this man for the big win!

Great service
Was referred to Peter by a police officer friend for Dupage DUI and received the best outcome possible given the situation - not guilty on all charges. Easy process, would recommend.

Overwhelmingly Pleased
The moment I sat down for my consultation, I knew I was in the right place. Mr. O'Connor was very detailed on the process of what could happen. Listed worst case scenario's and we discussed what my goals were for the outcome of the case. Peter walked me through every thing I could do to help my case, and I followed his guidelines. It was teamwork - I did the work he suggested on my end, and he did his work on his end. Even after my sentencing, there were some "burps" in the system, and he did not hesitate to help straighten them out. Let's just say, I am extremely grateful for his services, and I will continue to recommend Mr. O'Connor to anyone in need! (Peter, if you are reading this, THANK YOU THANK YOU THANK YOU for all your help!!!)

DUI Case
I would like to thank Peter and everyone from Ramsell & Associates who helped me in my DUI case. I did not lose my license and am very grateful. Thank you very much.

Thank you Mr O'Connor!
For roughly 3 months I was stressing out expecting the worst from my court case. Mr. O'Connor made the process so much more easier and helped me out! I'm incredibly thankful for his help. I got into an accident on a suspended license, I was facing a class A misdemeanor. Mr. O'Connor was able to remove the misdemeanor charge, get me court supervision and remove the ticket from my record. (Keep in mind too I have a slightly horrible driving record) I was in the court room for all of 5 minutes, if even that. It took longer to find parking than it did to hear my case. Being 19 years old, I could have easily messed up my record. Thank you again Mr. O'Connor for helping me!

Great Lawyer and the best at DUI cases
Peter and the frim he works with is one of the best in the industry! Their expertise with the DUI laws allowed me to keep my license and managed to dismiss all moving violations associated with my case. I would trust no other firm with such a charge and best of all they quoted me one fee and stuck to that fee even with added court time. I highly recommend Peter and his frim Tony

Couldn’t ask for more
At the lowest point in my life- where I felt more hopeless and scared than I’ve ever felt- Mr. O’Connor walked me through everything with such care and understanding. Any time I was anxious or confused- he took the time to calm me and make sure I understood. As much as this will always be the lowest point in my life- with Peter as my lawyer- it wasn’t that bad.

Awesome and professional
Peter was very understanding and explained everything I could expect in my case. When calling with questions during my case he got back to me quickly and made sure I understood everything. Peter was able to get the minimum sentence for my case and helped get through the process and quickly as possible while making sure I received what I wanted at the outcome. Highly recommend!

Peter the Lifesaver
I met Peter a few days after I was pulled over for a DUI. I was 23 at the time and determined to handle the situation myself and Peter made that happen. He was incredibly understanding of me not wanting my parents to find out (they still haven't). This is a field Peter is very familiar and comfortable navigating and he walked me through each step so that there were no surprises. He was a pleasure to work with and I was even able to hire him to handle my final court appearance, since now, a year later, I'm in graduate school! Thanks again PGO

Pete O’Connor DUI Defense
Pete did an amazing job managing my case, was so patient with my questions/concerns through the whole process! He gave me as much insight and information that he could to reassure me that I’d get through this process somehow. This was my first DUI offense, had a clean background, and Pete was able to negotiate a plea to rescind my summary suspension with the Lombard township at the very first court hearing, which not only saved me from having a suspension of my license but saved my career ultimately. So pleased with the outcome of my case thanks to Pete!

DUI Case closed on first appearance !
I highly recommend this attorney, Pete is a very smart DUI attorney and knows well how prosecutors work. He listened and analyzed all the details from the traffic stop to arrest and release and put a complete proactive plan for the first appearance date. Not only was he able to conclude my case on first appearance but also negotiated getting my license back on that same day and avoided the suspension all together. thanks Pete, this meant so much to my family and career.

Thank You
Peter Did an Amazing Job with my case. I greatly recommend him if you find yourself with a DUI offense. I was unfortunately facing a second DUI conviction. Peter clearly explained my legal situation and went to work fighting my case. He was completely successful in bringing my second offense down to a Reckless Driving. I never lost my driving privilege and was able to continue with my career witch depends on driving. For that I will always be truly grateful for his expertise in court. Thanks Pete!

Serious Jeopardy
Mr. O'Connor represented me in a case where I was facing two class A misdemeanors. The legal strategy he employed resulted in the charges being dropped before trial. I found Mr. O'Connor to be a personable yet serious fellow.

Patient, Respectful and Knowledgeable
My actions were in large part stressful and shameful, but Peter George O'Connor demeanor helped alleviate the negative feelings and he helped me feel as though I was not alone. It is also reassuring that he works alongside a team of an intelligent and hardworking team that did not hesitate to answer my questions and/or direct me to someone who would answer my questions if they themselves were not able to assist.
