I am a public servant who believes in True Regional Collaboration. — A proven leader who has built consensus among diverse stakeholder groups. — It has been my priority to re-establish and strengthen regular communication with ACHD’s partner agencies with a regional dialogue focused on addressing the unprecedented growth facing our county–finding real solutions to deal with congestion. — Championed positive relationship building with partner jurisdictions, helping to avoid costly litigation and broker collaborative solutions that benefit all taxpayers of Ada County. — I have encouraged regular joint meetings between the Commission and all six cities in Ada County (Boise, Eagle, Garden City, Kuna, Meridian, and Star).


I am a consistent voice for Fiscal Responsibility with taxpayer funds — I have fought against property tax increases including a proposed 24% increase of ACHD’s portion of property tax last year to ensure more of your hard earned money stays in your pockets. — I advocated for and helped realize unprecedented financial support from the State of Idaho to help mitigate the impacts of the state’s highway system on local roads within Ada County. — I have successfully advocated for and support gap projects throughout the District, addressing needs such as school crossings, sidewalk gaps, signage, and Safe Routes to School, among others. — I continue to work to streamline processes at the District, allowing it to serve residents more efficiently with significant cost savings.


I am a strong proponent of a Community Focused approach to representation — I have been open and accessible to all, demonstrating a willingness to meet directly with constituents on-site to observe and fully understand their issues while working to find constructive resolutions. — I advocate for and promote transparency in the business of the District. — I have helped foster a constructive and positive culture at the District, ensuring that all stakeholders have a seat at the table and an opportunity to be heard. – I work to find real solutions to congestion throughout Ada County.Ada County Highway District Commissioner District #4
