MCGARVEY LAW

Roger Sullivan

Over the course of the last 35 years Roger’s legal career has focused on two objectives: securing justice for Montana’s workers and advocating for Montanans’ constitutional right to a clean and healthful environment.

Roger has litigated a number of landmark cases in both the environmental and workers’ rights fields.  He has been named Trial Lawyer of the Year by the Montana Trial Lawyers Association for his advocacy on behalf of Montana’s workers, and Conservationist of the Year by the Montana Environmental Information Center for his environmental advocacy.

Roger is especially proud that his clients have twice been honored with the Citizens Award by the Montana Trial Lawyers Association: the Advisory Committee for the Columbia Falls Aluminum Company Profit Sharing Class Action which succeeded in securing settlements in the range of $100 million; and Libby asbestos victims recognized for their successful efforts in the courts and in defeating corporate bailout legislation at the state and national levels.

Roger is admitted to practice in Montana’s state and federal courts; the U.S. Court of Appeals, Ninth Circuit; and the U.S. Supreme Court.

Roger is an avid outdoorsman and enjoys hiking, skiing, sailing, and fishing—especially with his children and grandchildren.
