Amazing Job
He did an excellent job with my case and was great about explaining everything. Listen to what he says and let him do his job and you'll get the best result you can. After three years of pretrial and three weeks of trial I couldn't be happier with his advice throughout the process.

Helpful at Each Step of the Process
Jason Corner took my case and as a first time DUI offender his experience and breadth of knowledge was extraordinarily helpful. He helped level set expectations and walked me through the process. At each step of the way he let me know what to expect and with his help I had a highly favorable outcome of a bad situation. Jason is very personable and I highly recommend his services to anyone facing a DUI charge.

Excellent Results (1st DUI/No Blow)
Mr. Korner got me through a very tough situation. I was pulled over for speeding and ended up with my first DUI in the infamous Town & Country area. I did not blow. Mr. Korner analyzed my video and police report and saw that the arresting officer did not follow proper procedure. That caused the "Do Not Blow" to be won against the DOR (which is rare) and I got my license back quickly. Then, the prosecutor had no legs to stand on for the DUI itself. I ended up with the speeding reduced to illegal parking and a two point, Careless and Imprudent Driving. Court costs in my area were just over $550 total. Mr. Korner used to work with the prosecutor in the St. Louis area and knows the ropes. He was extremely helpful in my case. He isn't the cheapest lawyer, but he is far from the most expensive lawyer (I met with 3 before making a decision). Do not go with the cheapest lawyer you can find! I can honestly say Mr. Korner was the best money I had to spend in a long, long time.

The Best Around
Mr. Korner was a fantastic help to me. He and his staff are extremely knowledgeable and made me feel very comfortable in a situation and process I was highly unfamiliar with. He was excellent in his follow up and made sure my case was handled professionally and with the most favorable outcome for me. I would definitely refer him to any of my friends seeking legal counsel-thank you Jason!

Simply the best!
My experience with Jason was extremely positive. On both a personal and professional level Jason treated me with the utmost respect. His attention to detail and knowledge base is incredible. I was kept informed throughout this process and from day one felt very relieved to know Jason was in my corner. Without a doubt I would hire Jason again and would only feel comfortable referring those in my situation to him.

The BEST attorney I could have ever wanted
Jason Korner went so above and beyond for me, I don't know where to begin. I trusted him with my life, and I'm glad I did. He made me so comfortable about our decisions, I never regretted anything about the entire process. I had many questions and reservations along the way, but he was extremely thorough in his communication and made every effort to help me understand the legal process and all of my options. He was diligent and commanding in court, and I feel very lucky to have had him on my side. I could not have had a better attorney. This person is very good at what he does. He knows the law and most definitely has a passion for it. He cares about people, and you aren't just "another client". If you want honest, hard-working, and dedicated legal counsel, then this is who you need to call. Period. HIGHLY RECOMMENDED. Thank you again Jason. You gave me possibilities. You gave me my life back. And I am forever grateful.

Client Review
Jason Korner took my case and was very informative and reassuring throughout the ordeal. I was expecting the case not to go in my favor at all, but he was able to take a very difficult case where the odds were not in my favor and I ended up with a very minor charge. Even a few years later, he has continued to be an additional source of information for me about my case as these things still come up in the future when dealing with school or future employers. I would absolutely recommend him to anyone who is in a tough spot and needs a really good lawyer to get them the best outcome possible.
