Overview
John Davis joined KesslerWilliams in 2020 after serving as an Assistant United States Attorney in the United States District Court, Eastern District of Missouri, for more than twenty-three years. As an Assistant United States Attorney, Mr. Davis was assigned to the Organized Crime Drug Enforcement Task Force.

These investigations involved the Drug Enforcement Administration (DEA), Federal Bureau of Investigation (FBI), United States Postal Inspection Service, Department of Homeland Security, Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF), and numerous other federal and state agencies. As a result, Mr. Davis is very experienced in global positioning system (GPS) tracking, wiretaps, and other electronic means of investigation.

Prior to becoming an Assistant United States Attorney, Mr. Davis was elected Associate Circuit Judge of the 11th Circuit in St. Charles County, Missouri. Before taking the bench, Mr. Davis' litigation career began as an Assistant Prosecuting Attorney in the St. Charles County Prosecuting Attorney's Office, where he gained extensive trial experience in felony, misdemeanor, and traffic matters on the state level. He also practiced before the Missouri Court of Appeals for the Eastern District.
Mr. Davis has over 20 years of experience as an adjunct professor of criminal justice at Lindenwood University. His teaching experience includes Constitutional Law, Criminal Investigations, Criminal Justice, and the Law of Evidence.
A native of Peoria, Illinois, he graduated from Bradley University, with a B.S. in Administration of Criminal Justice, and Saint Louis University School of Law.

How do I choose a lawyer?
Consider the following:
- Comfort Level – Are you comfortable telling the lawyer personal information? Does the lawyer seem interested in solving your problem?
- Credentials – How long has the lawyer been in practice? Has the lawyer worked on other cases similar to yours?
- Cost – How are the lawyer's fees structured — hourly or flat fee? Can the lawyer estimate the cost of your case?
- City – Is the lawyer's office conveniently located?
Not sure what questions to ask a lawyer?
Here are a few to get you started:
- How long have you been in practice?
- How many cases like mine have you handled?
- How often do you settle cases out of court?
- What are your fees and costs?
- What are the next steps?
Want to check lawyer discipline?
It is always a good idea to research your lawyer prior to hiring. Every state has a disciplinary organization that monitors attorneys, their licenses, and consumer complaints. By researching lawyer discipline you can:
- Ensure the attorney is currently licensed to practice in your state
- Gain an understanding of his or her historical disciplinary record, if any.
- Determine the seriousness of complaints/issues which could range from late bar fees to more serious issues requiring disciplinary action.
