Mosinee High School Home

Welcome to Mosinee High School!

I am proud to welcome you to Mosinee High School for the 2025-2026 school year. Having grown up in this community and raised my family here, it is truly an honor to step into the role of principal and serve the students, staff, and families of Mosinee.  

I began my career in education as a middle school English/Language Arts teacher at Marathon Venture Academy. After 12 years in the classroom, I transitioned to supporting schools throughout the Midwest and across the country as a school coach and professional development specialist for EL Education. Most recently, I spent the last eight years as an Associate Director of Continuous School Improvement, where I supported teachers and school leaders in the 22 districts of the CESA 9 region. I am thrilled to bring my experience back home and work alongside an exceptional staff.

Throughout my career, I have come to believe that education must be personal, authentic, and innovative to best prepare students to confidently face the opportunities and challenges of the world ahead. Mosinee High School is committed to this same vision, making every moment matter for our students. With a dedicated staff and a strong partnership with our families and community, we will do great things for our students!  

Please feel free to contact me with any questions or suggestions.  I am excited for all that we will accomplish together under the vision and values that make Mosinee High School personal, powerful, and future-ready.

Welcome Back Mosinee Students and Families!

As we prepare to open our doors for another incredible school year, I want to share how truly excited we are to have our students back in the building. At Mosinee High School, we are future focused—meaning students will begin their journey of mastery by taking ownership of their learning while keeping an open mind on college, career and life pathways. We will remain curious, resilient, and intentional as we define our success not just for tests but for life beyond the classroom. 

As I begin my second year as Assistant Principal, my focus remains grounded in a simple but powerful goal: to make every moment matter by building the competencies for students, staff and our community to thrive together.

This means continuing to lead with purpose—by intentionally building the conditions where all stakeholders can see and achieve potential they may have never believed possible. It also means working to empower voice and choice—by enhancing opportunities for everyone to lead, explore, and create through authentic, hands-on, and exploratory learning experiences.

Let’s make this year unforgettable. Let’s make it matter.
