My interest in teaching mathematics started in January 2002. It was the first day I worked as a mathematics tutor in Mathematics Department of Minnesota State University Moorhead. I could see that students liked the way I explained mathematics concepts to them.  I enjoyed it as I saw them learn the math concepts and skills.   After tutoring, I told my sister that I wanted to teach mathematics or statistics. In two years, I took all mathematics and statistics courses offered at Minnesota State University Moorhead. In my final year, I was awarded “Certificate of Achievement for Excellence in Undergraduate Mathematics”.  That gave me even more confidence and I made up my mind to teach mathematics at college level one day. After I graduated with a M.S. in Mathematics in 2006, I went back to Minnesota State University Moorhead to work as an adjunct and math tutor. In 2007, Northcentral Technical College was looking for a mathematics instructor with a Masters in Mathematics.  I applied. In July 2007, I was offered the mathematics teaching position. I was extremely happy and no words could express my elated emotions. The abundance of my academic backgrounds definitely helps to enhance my teaching and provide NTC’s students a different perspective on mathematics learning. It is a wonderful feeling to see students’ eyes light up when they realized they have grasped the challenging math concepts or skills.  I appreciate every day that I have this great opportunity to do what I like in this beautiful country, truly the land of opportunity.

One of the things I love most about my job is that I get to work on math all the time!  How fun!  Another thing I love most about my job is that I get to work with students and help them to understand the math concepts we use in class.  My students make my job even more enjoyable.  I’ve been teaching math here at NTC for 18 years and still love it. Some of my interests include reading a good Steven King novel, watching plays at the theater, and traveling.  One of my goals is to visit every state in the U.S. at least once – I’m about half way there.  I wish cooking was one of my interests and am forever checking out good healthy recipes, but I just plain old don’t like to cook no matter how hard I try to convince myself that I do.

Hello, my name is Kim Waltz, and I grew up on a pig farm in a little town called Adel, Iowa, just west of Des Moines. Currently my parents still raise corn and soybeans on that farm. I have two siblings; my sister, who farms with my dad, and my brother who lives in Los Angeles, CA and works with autistic children. My wonderful husband Matt and I have a son named Levi and a daughter named CeCe. We moved to Wausau from Iowa in 2002. When I’m not grading papers or changing diapers, I really enjoy playing golf, exploring new bands/music, and creating pottery on the potter’s wheel at the Center for the Visual Arts in Downtown Wausau. I never dreamed that I would live in Wisconsin and be an instructor at NTC, but what a wonderful dream it has turned out to be!

My interests include reading, running, mountain biking, and learning.
