Our Story

McGarvey Law’s roots trace to 1975 when Jon Heberling joined Dale McGarvey’s practice. In 1986 Roger Sullivan and Allan McGarvey joined as partners to create one of Montana’s premier firms dedicated to protecting the values and land of Montanans. In 2020, John Lacey, Ethan Welder, Dustin Leftridge, and Jinnifer Mariman joined Roger and Allan as partners in McGarvey Law.

We focus on ensuring healthy communities, safe places to work, and a clean environment. The firm represents individuals suffering from the effects of exposure to dangerous substances, especially those suffering from Libby asbestos diseases. We also advocate on behalf of individuals denied the right to work in a safe and healthy environment and represent private property owners in achieving the clean-up of contaminated lands.


Our mission is to advocate on behalf of communities and individuals who are attempting to seek justice and to pass on clean and healthy communities to the next generation of Montanans.

The case of the century

The Libby Asbestos case is the largest personal injury case ever filed in Montana. McGarvey Law won settlements over $100,000,000, and is still fighting to this day to ensure the people of Libby regain some of losses they suffered.
