Engineering Our Future!

Tatanka Elementary STEM School - Engineering Our Future!

Tatanka Elementary STEM School (TESS) is a magnet school with a specialized curriculum that helps students become thinkers and problem solvers.  Here, Science, Technology, Engineering and Mathematics concepts are integrated into classroom lessons. Through these experiences, students Collaborate, Communicate, Think Critically, and use Creativity to develop a deeper understanding of all the STEM components.  We build upon children's natural curiosity to help them research questions, investigate problems, and develop answers using STEM concepts.  This active, "minds on" approach prepares students with the skills they need to be successful in the 21st century.  Tatanka serves approximately 530 students in grades K-5. TESS is a neighborhood school and a school of choice, as part of the Northwest Suburban Integration School District (NWSISD).

Dear Tatanka Elementary STEM School Community,

It is with great joy that I introduce myself as the newly appointed Principal of Tatanka Elementary STEM School! I am honored and humbled by the opportunity to lead our school community and to be part of your child’s elementary experience.

I’m coming to TESS from Minneapolis Public Schools, where I have been an Assistant Principal for the past 7 years. Before becoming an Assistant Principal, I had incredible experiences as both an elementary and middle school teacher. I attended graduate school at the University of Wisconsin-Madison where I studied Educational Leadership & Policy Analysis, and I received my Bachelor’s in Elementary Education from Dakota State University, a short distance from my hometown of Brookings, South Dakota.

Although I come to Tatanka with a variety of school experiences, my most coveted role is being a mom. My husband, Gil, and I have 2 children. Fenton (5) is a Kindergartener who loves math, reading, and science experiments. Oakley (3) loves playing in dirt, our Siberian Husky, Lajila, and reading anything she can get her hands on. I look forward to introducing my family to the Tatanka school community in the near future.

As I start as Tatanka’s Principal on July 1st, please know that I am committed to providing all TESS students equitable and inclusive learning opportunities where they create, explore, and experience the wonder of learning. I will strive to continue to build on the excellence and many successes already existing at Tatanka. I look forward to meeting each of you and building a partnership where our collective efforts result in amazing outcomes for every TESS student.
