LaMar F. Jost


P. 303.244.1905 | F. 303.244.1879


LaMar Jost defends high-stakes cases involving medical malpractice, product liability, mass torts, and complex commercial matters. He has handled significant professional liability and tort cases in 32 states, the District of Columbia, and in tribal courts. 

Through each stage of the litigation process, LaMar anticipates and responds to his clients' needs. He is aggressive in fact and expert discovery, proactive at mediation, and always ready to defend his clients at trial. As one client commented, he is "creative, enthusiastic, and a relentlessly hard worker."

LaMar has tried several eight and nine-figure multimillion-dollar medical malpractice and personal injury cases in California, Colorado, the District of Columbia, Florida, Illinois, Iowa, Maryland, Michigan, Minnesota, Nevada, New Jersey, Pennsylvania, South Carolina, Texas, Utah, and Wyoming. He has won a significant majority of those medical malpractice and wrongful death trials. He has won summary judgments for a Fortune 10 manufacturing company in Wyoming and Washington. He has won legal malpractice cases in Wyoming and Missouri. He has successfully briefed a matter of first impression under CERCLA in the Tenth Circuit and then successfully opposed the plaintiff's petition for certiorari from the U.S. Supreme Court. He has won Daubert and Frye-Mack motions and hearings in several jurisdictions. LaMar has also represented clients in federal multidistrict litigation in Pennsylvania and Massachusetts, and in cases remanded from multidistrict litigation.

In addition to trial work, LaMar has an active appellate practice. He has handled complex appeals for companies and individuals in a variety of practice areas, including constitutional law, environmental law, insurance, tort, professional liability, and intellectual property. LaMar has argued and briefed several appeals in the Tenth Circuit, Colorado appellate courts, Georgia Court of Appeals, and D.C. Court of Appeals, and the Wyoming Supreme Court. Through the appellate process, LaMar has assisted in making law favorable to hospitals, physicians, and industry.
