Hired Law firm 2019-2020John 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, kind, and helpful as I spent over 18 months working with JCS 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!

Hired Law firm 2018-2020John and his team are amazing. 10/10 on everything. They were always happy to assist me with any question that I had and put forth their best effort. If it wasn't for John and his team I would have gotten the worst deal in the world of ever ever. Because of John after a 2 year long battle with the state being uncooperative and constantly making excuses to delay my process John pushed back and fought and now I can pick my life back up and no longer stress about the situation. Thank you John
