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 John Schleiffarth 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 John Schleiffarth 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.
