About Lucas
A longtime resident of Montana, Lucas Foust founded his law firm in Bozeman nearly 20 years ago. He understands that hardworking Montanans don’t like asking for help—after all, he’s one of them!—but he prides himself on being a different kind of lawyer: tough and unwilling to back down, but not the egocentric bully many people imagine when they think of lawyers.
Born in Moscow, Idaho, Lucas grew up in Columbia Falls with four brothers and graduated from Columbia Falls High School in 1988. He attended college at Gonzaga University in Spokane, Washington, then returned to Montana for law school at the University of Montana in Missoula, where he earned a position on the Montana Law Review and the moot court team. After law school, he clerked for the Honorable W. William Leaphart of the Montana Supreme Court, began practicing law in 1997, and opened Foust Law Office in Bozeman in 1999.
In 2015, a life-changing experience at Gerry Spence’s Trial Lawyer College in Dubois, Wyoming, led Lucas to practice law with more compassion and understanding of where his clients are coming from. He has since led over 100 jury research projects—more than any other attorney in Montana—setting his firm apart and helping him successfully represent clients at trial time and time again.
As of 2026, Lucas serves as a policy advisor with the Keenan Trial Institute. He is also the proud father of three young adults and referees high school basketball games in Gallatin County.
