Kari easily connects with the diverse students, staff, families, and community members at Highlands and Odyssey.
Kari values proactive behavior management and inclusivity as she feels this creates positive classroom cultures for students and teachers. Kari believes a child's early education experiences set the stage for their future. It is her goal as the school leader to ensure all who enter her school are valued, respected, and provided excellent service.
When Kari is not at school, she can be found spending time with her husband and young children. Kari also loves soaking up the sun, cheering on the Packers, and scrapbooking.
