If your case involves complex facts encompassed in an immense amount of data, you’ll be glad Jessie Mahr is on your team. Jessie has spent most of her career parsing through and analyzing large data sets to find the needle in the haystack that so often makes or breaks a case, no matter how complicated the path may be. And she does it efficiently, with an eye toward each client’s individual needs and goals.

In addition, Jessie’s experience in drafting motions and pleadings, assisting at trial, and counseling clients allows her to find and separate the critical factual elements needed to make the most effective arguments. When interviewing clients and witnesses, Jessie draws on her background in clinical psychology, which allows her to read a room and vary her approach depending on the tone required for each situation.

Jessie’s upbringing on a farm in central Illinois has taught her hard work and dedication, as well as given her the ability to communicate with and relate to many different people, regardless of where they come from. The variance in her life experience allows for an understanding of unique and diverse topics and lends to understanding the background and experience of the people who will be sitting on the juries across the state.

When Jessie isn’t working hard, she is playing hard. She enjoys cycling and playing slow-pitch softball, though she still prefers 12-inch softball to the 16-inch softball popularly played in Chicago. She also enjoys traveling and singing karaoke.
