Fantastic Lawyer
Gus Kostopoulos did a fantastic job managing our case. He is prompt, assertive, and extremely knowledgeable. He is far superior than anyone else we have ever dealt with. We enjoyed our experience with him. He made everything so simple and seamless. On the day of trial he was able to win our case in the most perfect favorable conditions!

The Best Of the Best
Kosopolous Law Group. These guys are seriously top notch. I was arrested For Misdemeanor Domestic Violence in Naperville. After interviewing 4 lawyers in the area and doing my research I felt I'd get the best outcome with Gus and his team. He provided me with the knowledge and communication I needed as I had plenty of sleepless nights worrying about my outcome. The end result..GUS was able to get my cased dismissed! Honestly do yourself a favor and save the time and effort looking for another Criminal Defense Lawyer and hire GUS!

Great Attorney of the Law
Mr. Gus Kostopoulos made a great job getting my case dismissed, by the time that a case started I have no attorney because I never needed one before so I friend of mine indicated his services. I called and he received me in a meeting right the way to answer all my doubts and took care of my case precise, fast, carefully and conducted the case very well achieving a positive result in my favor.

Gus is Brillant!
Gus was co-counsel to my case. He was well versed in my situation and was present when issues arose. Because I was able to observe him with my case in the courtroom, I discerned he was poised, stealth like and a master of his profession. He and Joe along with Rosemary were synchronous in their strategic plan of winning my case. Because of their competencies, my case was dismissed and then was expunged. My lawyers believed in me and I knew I was in the best hands. My review is not only based on my outcome; it is based on the realization that this law firm is superior throughout the client-attorney relationship. The bonus for me was, I believe there are attorneys who will go the distance to make sure the law is upheld and a wrong is corrected. I have my life, profession and integrity restored and I sincerely want to thank you Gus, Rosemary and Joe...I will be forever grateful.

2nd dui reduced to reckless driving
Highly recommend Gus. He helped me out when I thought it was a lost cause. 2nd Dui, blew .21, marijuana and open alcohol in the car, and a child in the car. He fought hard for me and got it reduced to a reckless driving. He made a miracle happen and that's just what the judge said too. I would have faced jail time and revocation of my license. If anyone is in trouble this is the guy to go to. He helped save my life after I hit rock bottom. Words couldn't express the amount of gratitude I have for him.

Case dismissed
I had a different attorney before I hired Gus, I wasn’t confident I had a chance winning my case. I went in to get a second opinion and Gus and his team instantly put my worries at ease. I hired them on the spot. They were very responsive and explained everything that had to be done. Rosemary met with me at the courthouse and had my case dismissed.

Wonderful experience
I was filled with worry over my case, but a good friend referred me to Mr. Kostopoulos. I was charged with criminal damage to property and was terribly afraid this case would ruin my record. However Mr. Kostopoulos put my mind at ease. He explained the best course of action with honesty and courtesy. He worked very hard on my behalf and to fully explain my case to the judge and prosecutor. Thanks to him my case was dismissed. I am very grateful and thankful I chose Mr. Kostopoulos as my attorney. I would recommend him to anyone in need of legal help. Hire him and he will make sure you are treated fairly and give you the very best results!

He Really Cares About His Clients.
I am very satisfied with the representation that I received from Gus. He put a lot of time into my case and seemed to really care. In the end, I did not go to jail and I avoided a criminal record.

Case Dismissed
I hired Kosta Kostopoulos for a difficult case that was affecting my career. We went to court and he got the case dismissed that day. I would recommend Kosta Kostopoulos for anyone that is looking for a very effective lawyer that gets the job done.

An Incredible Lawyer! Got my Case Dismissed!
I was arrested for a criminal case where I could have gone to jail for a long time. I am a professional who had never been in trouble before and was terrified of jail, a criminal record, and the loss of my livelihood. I met Gus in his office and he detailed a strategy that we could use to try to get my case dismissed. When we went to court, the prosecutor would not even consider dismissing the charges against me. But Gus would not take no for an answer, and was tireless in fighting for me. Gus was later able to get the criminal case against me completely dismissed! All I had to do was pay a small fine of a few hundred dollars on petty traffic ticket. It is a wonderful feeling to have your life back. Over the years, I have since sent many friends and acquaintances to the Kostopoulos Law Group. These lawyers have gotten felonies, DUIs, Domestic Batteries, Drug cases and other cases completely dismissed. When a case could not be dismissed, they have often negotiated for reduced charges and no jail. Every single person whom I referred has thanked me for the referral and told me that they are very happy with the results they received from these lawyers.

The Best Lawyer I Could Have Hired
After consulting with many lawyers, Gus was the best decision I made. Gus was reasonable with the price and really went out of his way to help me win my case. I picked the Kostopoulos law firm because they knew the judge in my case and were realistic in the outcome to expect. My domestic battery case was dismissed and Gus is helping to get the case expunged. After receiving quotes 2x - 3x the price I was quoted, I knew the Kostopoulos law group was the best choice. I've never met a lawyer who was so helpful and genuine. I am going to recommend their services to all my friends and family who have legal problems. You can't go wrong with Gus and his talented team!

Trusted team of lawyers
Gus and Joe took over Domestic battery charge case and it was the best decision I could have ever made. I had a lousy lawyer and had to fire him. They are a great team to say the least. Joe is responsive, and answers any questions you have and responds honestly. I was really scared I was going to be in serious trouble, since this was my 2nd offense. Joe showed up in court and had it dismissed and I was literally in shock. They are very helpful and know what they are doing. I highly recommend this law firm. Thanks again, Joe & Gus!

Great Job
The Kostopoulos Law group is really an amazing group of people. A few years ago I was arrested and facing a class 3 felony. After researching for the best attorney, i discovered The Kostopoulos Law firm, which was my best choice after hiring the team, they really took charge of my case. I was facing a prison sentence, however, due to the hard work of my attorney's, they got me the best results ever, which was just community service and etc. I was very happy with the outcome of my case. I will recommend The Kostopoulos Law firm to anyone. Thanks guys for the best outcome.

Highly Recommended
I had the opportunity to meet with Gus (Kostas) regarding a matter I was dealing with. He was very helpful and honest about how to best approach it. I felt like other attorneys tried to scare me so that I would sign with them. Gus explained to me that my situation was minor and I would be fine. As it turns out, he was right. I would recommend him to anyone need a criminal attorney.
