John and his team, especially Leigh, were outstanding throughout my case. They were professional, effective, and consistently available whenever I needed them. Their communication was excellent—every call or text was either answered right away or returned the same day. I always felt informed and supported, and their dedication made a stressful situation much easier to navigate. HI highly recommend their services to anyone in need of strong, reliable representation.

Top level attorney. John was always seemed a step ahead of things and in the end my case went the way I needed it to. No matter where this roller coaster of a case went John was always able to respond effectively. I hope I never need Johns help again but if I ever do I could not think of a better attorney to stand by my side.

John is one hell of a lawyer! I was going through a bad patch in life where alcohol was an issue. None the less I got in trouble back to back. I had two DWI's within 60days of each other which one was with a suspend license and a car accident. I was looking at jail time! He was able to get One DWI completely dropped and the Second DWI dropped to an SIS (Suspended Imposition of Sentence). I spent NO JAIL TIME thank god! I was able to set up payments with him. He honestly cares about you and he

This man did what he tried to do! This man fought long and hard to get me probation. He clearly explained everything and went through numerous files/videos. This man is kind, patient, very intelligent and trustworthy. I am glad I got to know this man, I wish the circumstances were different of course but everyone in their office is kind. I hope to see him again under normal circumstances, no more court for me. THANK YOU JOHN AND GOD BLESS YOU!!

I was wrongfully charged with multiple counts of a serious felony. I was facing up to 35 years in prison. I hired John to fight my case and the felony counts were all dropped. JCS law is the real deal. Now I have a great future again and can move on with my life

I did a LOT of research and calling before choosing John and I am so grateful for choosing him as my DWI attorney. From the first 30 seconds of talking to him, I knew he was the right choice to help me. I recommend him to everyone!!!!!

Facing a "Better Call Saul" moment, I contacted several firms in the St. Louis area and was most impressed by JCS Law. Andrew was professionally responsive yet very easygoing and helped extricate me from a potentially sticky situation.

He was very caring and compassionate. Even though I had no choice at the time, I had a lot of guilt and bad feelings about bankruptcy and John took all of those away. He helped me through it mentally.
