He not only helped get me through my cases but he gave me a piece of advice that saved my life and has allowed me to work toward the life I have today. Working with John has given me a second chance. If you are willing to put in the work, he will helped guide you through the legal process and see you through to the other side. John said that from the beginning and he is a man of his word."

Verified ClientHired Attorney 2017-2019I went in to talk to John not having any idea if what to do after being arrested. He offered his expertise and helped me to navigate my way through that two year period of my life. Any questions I had or concerns that I shared with John were met with quick replies. He not only helped get me through my cases but he gave me a piece of advice that saved my life and has allowed me to work toward the life I have today. Working with John has given me a second chance.

Verified ClientHired Attorney 2019-2020My nephew was arrested in Steelville, Missouri, on drug charges. We are from New Mexico and had no knowledge of reputable attorneys in St. Louis. I googled criminal attorneys and the law firm of John Shleiffarth came up. I called him, and he immediately called me back. He represented my nephew and always gave it 100%. The outcome was exactly what he indicated he would attempt to do. His expertise and professionalism, as well as his staff’s professionalism was amazing. I highly recommend using the law firm of John Schleiffarth

Verified ClientHired Attorney 2016-2019It's rarely a good thing to require an attorney's services, especially if it's a major traffic citation. Having been referred to John Schleiffarth & his team at JCS Law (by another attorney) was a godsend. During my initial consultation with John, I felt that I was hiring one of the best attorneys in the St. Louis area to handle my multiple citations. JCS Law handled my case very professionally and won a very favorable outcome/recommendation to what could've been a very serious and impactful verdict. JCS law made sure my driving status remained fully active during the lengthy court process I always keep John's Card in my wallet and his number in my phone in the unfortunate case that I or a loved one need his services.
