Litigation Star!
I can't speak highly enough of Mr. Hyun! He is absolutely one of the best trial attorneys in Chicago. I'm deeply impressed by his diligence, intelligence and professionalism. He is highly professional in handling a wide range of complicated legal issues and is always responsive, and he truly cares about his clients! Highly recommended!

Trustworthy and Attentive
My husband and I had a small business which we had for the past 40 years, We were sued by the local village for causing contamination to the area which was not true. We had hired two previous attorneys which we fired. But James was a fresh air. He was able to beat the case and negotiated a reasonable settlement which resulted in saving our business.

Hard nose and effective advocate
James handled my matter involving false accusation levied against me from the DCFS...He was patient, accurate and very sharp throughout the process. Through his hard work and follow-up, the case against me was unfounded...

Best Attorney (I've Had)
Mr. James Hyun is a class act. He is very attentive to his clients' needs, and communicates very quickly and efficiently. As an attorney, he is very professional, and full of integrity. There is no doubt in my mind that he has hundreds of satisfied clients. If I ever need someone with his expertise again, I would not hesitate to contact him.

Diligent and Result-Oriented
Mr. Hyun was very instrumental representing my matter in a criminal case. I was charged with a retail theft and he negotiated a deferment program and resulted in a acquittal. He was very diligent and communication was quite excellent. Highly-recommend

Mr. Hyun was tremendous in representing our son being charged with a very serious crime. While our first attorney recommended to take a plea deal, Mr Hyun took the case to trial and forced the government to downgrade the charge where it would not result in conviction. Highly recommended.

"I've known James for over 15 years and interned at his office while I was in law school. He is a great mentor and friend and I owe a lot of my own success to him. I've always considered James to be a very sharp attorney with excellent litigation skills. He is fearless in the courtroom and he is very well respected by his peers. I've referred several clients to him, because I have no doubt that they will be very well represented. After all these years, I still consider him a mentor and a life long friend."
