Jonathan Leach, LLC, is a trial consulting firm that helps attorneys, parties, clients, and witnesses present the best case possible. We are not a law firm. Instead we seek to enhance the practice of law by supporting the work of the legal practitioner. We do so by providing insights and information about litigation-related behavior and communication. We are based in El Paso, but our clients and cases are located throughout the United States.
Whether you need jury consulting, post-verdict research, witness training, or trial graphics, we tailor our services to your particular circumstances in order to help you feel more confident, more prepared, and more knowledgeable as your case goes forward.
Although as jury consultants we are most often retained by the attorney in a given case, we are also commonly enlisted directly by the client, or sometimes by an insurer. Once we join the team, we use our insights and expertise to help our clients understand and address the nonlegal or extralegal factors that are likely to affect the case.
Our primary focus is effective communications. We work with our clients to develop strategies for presenting the strongest possible case to a judge, a jury, an arbitrator, or a mediator. We bring more than 20 years of experience to this work. We are long-standing members of our professional society, the American Society of Trial Consultants (ASTC).
Our services include pretrial research, witness preparation, jury selection, courtroom presentation and strategy, and post-trial juror interviews.

Memorable cases include those involving the “Queen of Daytime Talk-Show Television”; the trademark for repositionable (sticky) notes; high-profile allegations of securities violations in a number of different venues; and the publicity rights of sports celebrities, among other matters.

"Jonathan: thanks for your help at the trial. I have asked [my client, a co-defendant] to contribute to your courtroom work, since we were ‘free-riding’ on it. I was very impressed with your insights."
"[Our expert] took the stand early this week and performed exceptionally. All of us were very impressed. His improvement as a witness was incredible. All of his hard work, and certainly his time with you, paid off in full."
"[The witness] stayed on message. There were even a couple of moments where he scored some really good offensive points. Ultimately, they scored no points at all on him. I have to say, this is one of the most improved witnesses I have ever seen."
"You were an extremely important addition to the trial team. This will not be a one-shot deal for you with TXU. I will certainly use you again."
"Jonathan, your patience and your keen sense of humor saw us through. Please accept my esteem and gratitude."
"Thank you, Jonathan, for your invaluable help. Your advice each evening, and your ability to quietly influence the outcome of the trial, was sincerely appreciated."
"I very much enjoyed working with you and was pleased with the focus groups, as well as the information you were able to provide as a result."
"Jonathan is top-drawer. His advice is invaluable when theming a case. He is also excellent in working with witnesses to ease their concerns, focus their message, and prepare them to withstand cross-examination."
"I’ve done projects with other jury consultants. This is the best jury-consulting experience I have ever had."
Contacting us early is key. The best time to begin consultation is early enough to adjust trial preparations and make course corrections, as the case moves forward. Typically, we get involved before discovery is underway. That is because, once a critical witness has been deposed, it can be difficult to “unring the bell” of the transcribed testimony and its ultimate influence on the jury. Virtually all of the tools offered by a trial consulting firm — jury research, theming, graphics development, witness training, and so on — are most effective when deployed well in advance of the target event. Adjustments to and fine-tuning of the case become possible when there is still time to do so.
