I have been a proud Teamster for 12 years, serving our members in a variety of roles that reflect my commitment to solidarity and advocacy. My journey began at St. Cloud State University, where I worked in the Residential Life program and quickly became active in union leadership. During that time, I was elected Campus Association President and served on the State Board of MSUAASF as the Grievance Officer, representing Administrative Service Faculty across Minnesota.

Within Teamsters Local 320, I have served as a Steward for 4 years, a Trustee for 1 year, and now as a Business Agent. Each of these roles has deepened my dedication to ensuring that members’ voices are heard and their rights protected.

I hold an MBA from St. Cloud State University and a Master’s in Higher Education Administration from Illinois State University. My academic background, combined with my union experience, gives me a strong foundation in organizational leadership, conflict resolution, and strategic communication—all skills I bring to my work advocating for Teamsters today.

I believe deeply in the power of collective action and am committed to building a stronger, more united labor movement that uplifts every member.
