Trial leadership
More than four decades of jury-trial experience in high-stakes personal-injury, wrongful-death, and business litigation. At Wren Cook he helps direct and lead the firm's trial work.
Full biography
Jim's role as lead trial attorney begins early: assessing the case with the trial team, identifying the evidence and experts that the trial will require, and building a targeted discovery plan. He then translates complex facts, data, and legal issues into a clear justice story for the jury, with focus-group jury testing before final trial preparation. Most cases resolve without trial — but every case has to be ready for one.
Before returning to full-time trial practice in 2025, Jim spent nearly two decades as a tenured Baylor Law professor, serving as the Leon Jaworski Chair of Practice & Procedure, directing Baylor Law's renowned Practice Court program, and co-directing its Executive LL.M. in Litigation Management — all while trying and consulting in billions of dollars of litigation. He still teaches Advanced Trial Preparation at Baylor and has trained thousands of lawyers nationwide.
His perspective is shaped by both sides of the docket: he spent the first third of his career trying cases for defendants before concentrating on major plaintiff cases, across medical malpractice, fiduciary litigation, product liability, securities, contract, patent, wrongful death, and business fraud.
Board certified in Civil Trial Law and Personal Injury Trial Law by the Texas Board of Legal Specialization and in Civil Trial Law by the National Board of Trial Advocacy, Jim served as National President of the NBTA and has held leadership roles with the American Board of Trial Advocates. He is author or co-author of multiple books and articles, including the 2025 edition (and upcoming 2027 edition) of Proving Damages to the Jury, co-authored with Laura Brown.

Freight brokerage liability & systems investigation
The jury system is the great equalizer — where everyday Americans can stand up to power and be heard. That is why Louie practices law: to hold large venture-capital and publicly traded companies accountable for the harm their corporate decisions inflict on injured Americans.
Full biography
He is now one of the country's preeminent thought — and action — leaders on freight brokerage liability, especially the use of chameleon carriers, doctored electronic logs, and other unlawful trucking operations, bringing the toll those operations take on families into court.
His work in this field began in 2024 with an extensive two-year international investigation into overseas chameleon carriers operating in the U.S. That investigation culminated in a civil RICO lawsuit against multiple freight brokers — among the first cases of its kind in the country.
Louie has represented families who lost loved ones to chameleon carriers hired by freight brokers, and speaks nationwide to trucking companies, victim advocacy groups, and captive insurance organizations. He has also worked alongside government officials and policymakers to advance legislation and enforcement that strengthen safety across the country. He believes the jury system is the great equalizer, where everyday Americans can stand up to power and be heard.

Jury strategy & trial science
Thirty years as a highly lauded defense lawyer — Texas Super Lawyer, Best Lawyers in Dallas — now Director of Baylor Law's Practice Court program.
Full biography
At Baylor Law, Liz became the first woman in 100 years to teach in the nationally lauded Practice Court program, taking over as Director in 2025. She now works almost exclusively on high-value, high-acuity plaintiff cases, turning the defense playbook into a strategy for anticipating the attacks and winning the plaintiff's case. Her ease with juries and her clarity of vision for the thematic and visual approach to a case strengthens every trial team, whether she serves as lead counsel or as a consultant.
Liz serves as a national ABOTA board member and chairs its Artificial Intelligence committee, hosts a monthly podcast on cutting-edge litigation issues, and writes books and articles — including with her favorite co-author, Jim Wren. She is unwilling to let corporate America use its size and financial resources to avoid responsibility.

Data and technology
Purpose-built analysis that connects entities, records, communications, and operational data.
Full biography
Joshua Weaver brings more than two decades of experience in software engineering, data systems, and technical consulting to complex civil litigation. He has developed technology for organizations including NextGen, the United States Air Force, and Chick-fil-A, as well as hundreds of technology startups. His work with artificial intelligence spans more than 15 years, giving him a depth of experience that predates the legal profession's recent adoption of AI.
Joshua's role on a litigation team is both strategic and technical. He works with counsel to identify the questions technology can help answer, locate relevant sources of information, and develop methods for examining records too large, fragmented, or interconnected to analyze conventionally. His experience includes custom software development, graph-database analysis, and the examination of complex corporate, operational, and transactional structures. He frequently leads the technical work of a case, translating its results into information that can guide pleadings, discovery, depositions, expert analysis, settlement evaluation, and trial preparation.
Joshua also has experience in early case assessment, jury research, and litigation focus groups. Over the past year, he has helped develop a docket of cases involving freight-carrier networks alleged to have used financial fraud, regulatory evasion, and human exploitation to obtain artificial pricing advantages. That work has required tracing relationships among ostensibly separate entities, reconstructing business operations from incomplete records, and identifying evidence embedded within deliberately opaque organizational and data structures. His current technology venture applies related methods to early case assessment and jury selection.
Joshua is the first person to serve as Director of Innovation and Emergent Technology for the State Bar of Texas. He also directs the Texas Opportunity & Justice Incubator, where he advises lawyers building sustainable practices designed to serve communities with unmet legal needs. A nationally recognized speaker, he regularly presents on artificial intelligence, legal technology, cybersecurity, access to justice, and the changing practice of law.
Joshua's work is distinguished by the integration of legal judgment and technical execution. He advises trial teams on the effective use of emerging technology and, when existing products are inadequate, develops purpose-built tools for the particular evidentiary and strategic demands of the case.
Behind the trial team — purpose-built data analysis and a national network of industry insiders and former federal investigators.
