LaMar F. Jost


P. 303.264.9562 | F. 303.244.1879
"LaMar is your attorney when you have a tough case with an aggressive plaintiff lawyer."
—General Counsel for the one of the nation's largest healthcare insurers


LaMar Jost has tried over 25 eight- and nine-figure cases to verdict across the country. In numerous other trials, his clients were dismissed after opening statements or reached favorable settlements. He has been lead trial counsel in 32 states, the District of Columbia, and in tribal courts. After LaMar saved clients $122 million in damages in 2023 alone, Law Week Colorado named him a 2024 Top Litigator. 

LaMar focuses his trial practice on high-stakes medical malpractice and personal injury cases. He loves trial, medicine, doctors, nurses, and the adversarial process. Because of LaMar’s dedication to his clients and willingness to try the toughest cases in the most challenging jurisdictions, he serves as national trial counsel to healthcare institutions, healthcare insurers (primary and excess), and academic health organizations across the United States. 

To LaMar, trial practice is about compassion, empathy, preparedness, and exposing fraud. He believes in the jury system and individual jurors, even in the “nuclear verdicts” environment. His longtime clients know him as a lawyer who wins against all odds. After LaMar won a trial opposite a top plaintiff lawyer, a client said, “I felt like I was in a master class on litigation watching the WTO team. So good!”

LaMar is licensed in over 30 jurisdictions across the United States. He teaches trial practice and medical liability courses at universities, colleges, and for legal associations nationwide. He has written two books in the medical-legal field and seven book chapters. LaMar routinely presents to healthcare institutions and insurers on trial practice, the current state of healthcare claims, and medical malpractice. He serves on numerous legal and public-interest committees. He has received several awards, including Best Litigator, Super Lawyer, and Top Personal Injury Lawyer.
