Rob Farris-Olsen

Rob graduated from the University of Montana School of Law, with honors, in 2011. After graduating, he returned to Helena and served as a law clerk to Justice Michael Wheat of the Montana Supreme Court. From there, he went to work for Montana Legal Services Association to help Montanans avoid foreclosure and litigate consumer debt issues. Rob joined Morrison, Sherwood, Wilson & Deola in 2013. His practice is focused on consumer and civil rights law.

Since joining the firm, Rob also started his political career. In 2015, he was elected to the Helena City Commission, where he found a way to fund Helena’s infrastructure needs by fairly charging those entities that use them the most. Three years later, in 2018, Rob was elected to Represent House District 79 in the Montana House of Representatives. In his first term, he co-sponsored the Medicaid Expansion bill, fought to protect Montana survivors of sexual abuse, and joined a bipartisan effort to fund Montana state parks, trails, and aquatic invasive species prevention. 

Rob lives at the base of Mount Ascension with his partner Erin, and their two children.
