“My work in public service started on the ground in South Dakota, organizing and canvassing for the Stephanie Herseth, Barack Obama, and Hillary Clinton campaigns. Those early efforts laid the foundation for a career defined by discipline, communication, and results. In 2022, I served as Communications Director for the Donn Larson for District 16 Senate campaign, where I led messaging strategy, media engagement, and voter outreach operations. Currently, I am the Deputy Director for the South Dakota Democratic Party.” (Candidate Campaign Website)
“I believe that my grandfather's Democratic Party still exists today, and his neighbors' Republican Party still exists today. We still care for one another, even when it feels like we're divided. That belief in community over division continues to guide my public service.” (Candidate Campaign Website)
“Outside of my political work, I am an avid outdoorsman who enjoys hunting, fishing, kayaking, tubing, and traveling. I also own and operate my own photography business.” (Candidate Campaign Website)
