LaMar: The Trial Lawyer Taking on America’s Largest Medical Institutions

In the high-stakes world of medical malpractice litigation, few attorneys command as much respect—and fear—as LaMar. With a national trial practice and more than 50 eight- and nine-figure cases brought to verdict across the United States, he has built a reputation as one of the country’s most formidable courtroom advocates.

LaMar focuses primarily on catastrophic personal injury and medical malpractice cases. But for him, trial work is about more than courtroom victories. His approach combines deep medical knowledge, relentless preparation, and genuine empathy for clients whose lives have been permanently altered by negligence. That philosophy has helped him secure landmark outcomes, including a recent eight-figure verdict against the Mayo Clinic in Rochester, Minnesota—the first successful medical malpractice verdict of its kind against the renowned institution in its hometown.

A National Reputation in Trial Law

Over the course of his career, LaMar has served as lead trial counsel in 35 states, federal courts, the District of Columbia, and tribal courts. Known for taking on exceptionally difficult cases in challenging jurisdictions, he has earned a reputation for strategic precision and fearless advocacy. In numerous trials, opposing parties have dismissed claims or reached favorable settlements immediately after opening statements.

His work has earned widespread recognition, including:

• Law Week Colorado Top Litigator (2024)
• Colorado Super Lawyers (2018–2025)
• Best Lawyers in America (2022–2026)

Mastering Medicine to Expose Negligence

One of LaMar’s defining strengths is his command of complex medical issues. Together with his trial team, he immerses himself in the science and medicine behind every case, enabling him to challenge elite medical experts and uncover negligence in highly specialized areas of healthcare.

He believes deeply in the jury system and sees jurors as the ultimate safeguard of accountability when patients suffer devastating harm at the hands of powerful healthcare institutions.

Educator, Author, and National Speaker

Beyond the courtroom, LaMar is also an educator and thought leader in trial advocacy and medical liability law. He teaches trial practice nationwide and has served as faculty for organizations such as the ABA-ABOTA National Trial Academy and CBA-CLE.

He is the author of several respected legal publications, including:

• Deposing Experts in Medical Malpractice Cases (2023)
• Medical Records as Evidence (2017)

In addition, he has contributed chapters on witness preparation, cross-examination strategy, and civil litigation procedure to leading legal reference works.

Endurance Beyond the Courtroom

LaMar’s discipline extends far beyond litigation. An accomplished endurance athlete, he has completed multiple 100-mile ultramarathons and extreme endurance challenges, including the Lead Challenge in Leadville, Colorado and the R2R2R ultrarun across the Grand Canyon.

That same endurance mindset—mental toughness, preparation, and resilience—has become a defining characteristic of his legal career.

More Than a Trial Lawyer

LaMar’s career reflects a rare combination of courtroom skill, intellectual rigor, and personal conviction. In an era where major healthcare systems often wield enormous institutional power, he has built his practice around holding them accountable and fighting for patients and families seeking justice after life-changing harm.
