Welcome to Life Science

My name is Tim Guldan, and I'm excited to be here for my second year at Dakota Meadows. This is my 6th year as a science teacher and I absolutely love working with students, and learning why the world is the way that it is!
I'm a MN native, growing up in New Ulm (where I still live) and I'm glad to call it home. I received my B.S. degree from South Dakota State University and spent the next four and half years teaching at Cathedral High School in New Ulm.


Mankato has always had a special place in my life - my family and I have a 25 acre vegetable operation and have been vending at the Mankato Farmers' Market for over 20 years, so if you've stopped by, you've probably seen me! Outside of teaching and farming, I'm a co-owner of a DJ company, TBG Entertainment, and simply enjoy being outdoors.


As your teacher, I'm happy to answer any questions that you may have. In fact, its my job to confuse you so you HAVE questions and we can learn new things together! I look forward to working with you this year as we explore the living world.
