- As a member of the Montana House I will advocate for affordable and accessible healthcare and case management services.
- I support a high-quality K-12 public school system and the Montana University System, including our two-year colleges and workforce development programs (certificate programs, apprenticeships, trades).
- Public lands and waterways are a great asset and significant driver of economic activity in Montana and access must be defended.
Affordable and accessible healthcare and case management services are quality of life issues. I support Medicaid expansion and will advocate for the restoration of the positions which have been cut from the Department of Public Health and Human Services (DPHHS). Early intervention and appropriate case management will save significant resources in the long term.

Scorecards
Ascorecard evaluates a legislator’s voting record. Its purpose is to inform voters about the legislator’s political positions. Because scorecards have varying purposes and methodologies, each report should be considered on its own merits. For example, an advocacy group’s scorecard may assess a legislator’s voting record on one issue while a state newspaper’s scorecard may evaluate the voting record in its entirety.
Ballotpedia is in the process of developing an encyclopedic list of published scorecards. Some states have a limited number of available scorecards or scorecards produced only by select groups. It is Ballotpedia’s goal to incorporate all available scorecards regardless of ideology or number.
