If you're looking for a criminal defense attorney who truly fights for his clients, look no further. John was exceptional from start to finish. His knowledge, dedication, and compassion gave our family hope during one of the most difficult times of our lives. He was always professional, honest, and genuinely cared about getting the best possible outcome. We are forever grateful for everything he did for our family and cannot recommend him highly enough. Five stars isn't enough!

I had a great experience working with John. He handled everything quickly and professionally, explained the process and the reasoning behind it clearly, and stayed to make sure everything was taken care of before I left. I really appreciated his professionalism, attention to detail, and willingness to go the extra mile. I’d highly recommend him to anyone looking for reliable legal assistance.

I had a great experience with Mr. Kopp. He was very knowledgeable, communication was great, & he was on time. Always answer any questions I had & made it easy for me to be able to obtain any documents I needed. I will be referring him to family/friends for any future issues.

I know for a fact your getting a great lawyer in John. Im not one to sit here and write B.S reviews and talk about things that aren't true. I'm gonna tell the truth and if I had anything negative to say I'd definitely say it. The fact is that I don't have one bad thing to say about John. Great lawyer. He's absolutely worth every cent. My real concern was hiring a Kane County guy even though my case is in DuPage. In the end it didn't matter. He walked there like it was Kane County. He knew everyone and you couldn't do better then John for your legal concerns.

Professional, honest/transparent, experienced, easy to talk to. I found John through simple Google search and was able to set up a meeting with him right away. He explained to me all the potential and the likely outcomes and was very transparent about them. Throughout the whole process, he was very informative of the situation and explained the possible routes we could take. Long story short, I was actually able to receive better than expected results going into his office. Thank you.
