Always choose JCS Law Firm Mr. John Schleiffarth = "Honor and Trust"

Mr. John Schleiffarth October 12, 2025 120 South Central Ave., Suite 1550 Clayton, Missouri 63105 314-561-9690 Dear Mr. Schleiffarth I appreciate this opportunity to express my sincere gratitude for your exceptional legal work achieved on my recent Case in Franklin County Missouri. ... I was charged with Displaying a Firearm when I unexpectedly discovered a trespasser tampering with our home Video Security System. I thought the indictment was some type of hoax or an error. It wasn’t long when I realized what I was faced with and what all was at stake. What rights I could lose along with years in a correctional facility. This could have affected the rest of my life in the most awful way. For years a good night’s sleep was difficult to find. It was early in the Case when you first visited the scene, my home, that things changed for me. It was at that time until the Trial was over, that not one stone was left unturned by you or your staff. You and your Team had the ability to not only perfectly communicate what was seen thru my eyes but prove the trespassers claims to be totally false. Hundreds of Photos, Exhibits and Testimony were professionally organized and put out in front of the Court and Jury. Your professionalism, experience, and dedication was flawless throughout this trial. In the end and due to your Firms relentless, exhausting work ethic you achieved a Not Guilty Verdict. I highly recommend JCS Law Firm to anyone. It has been my complete privilege to have had JCS Law Firm at my side throughout this process. Thank you again. Sincerely, Anonymous (contact JCS for additional info if needed)

Great Results

I hired JCS Law to help me get my Federal probation terminated. John and his staff were able to successfully get my case resolved in less than a few months.

Life changing results

John and his team had my DUI reduced to a non-criminal traffic violation. Despite my BAC and the officers all following procedure to the T —- they leveraged their relationships with the local District Attorney and Judge to consider who I am as a person and my lack of priors. Whatever your walk of l...ife, mistakes happen - - - John and his team helped me ensure mine did not roadblock my present and future. Their whole team also were highly responsive via phone, mail and text during this stressful time for me, which was extended due to the pandemic. Results matter - that’s the most important thing when you’ve gotten yourself in trouble!

Incredible attorney, delivered amazing results!

John Schleiffarth is simply incredible! His calm nature, open communication, and brilliant strategies helped us through a very difficult time. While most lawyers were disinterested in my federal case, John was inquisitive and provided hope that more can be done. John's entire staff is professional, k...ind, and helpful as I spent over 18 months working with John from our first meeting through sentencing. John is everything you would want in an attorney, I was lucky to have him on my side. John always told me the truth both good and bad and provided me with leveled expectations from start to finish. I trusted John from our first conversation, and so did my family. In the end we got the best possible outcome of probation when years in prison seemed inevitable. Thanks again John!
