Hello, I am Mark Rentschler, and I teach junior high science. I live in Larchwood with my wife, Penny, and our offspring Veda, Xander, and Malison. We also have the most superior cat in the universe, Kirby. Additionally, we have Finley, who is tied for the most superior cat in the universe. I grew up in rural Inwood, IA and proudly attended West Lyon. I graduated from Southwest Minnesota State University in Marshall, MN. I began my teaching career at Lincoln High School in Sioux Falls, SD. Currently, I am in my sixteenth year of teaching at West Lyon.

I also coach junior high football as the eighth grade head offensive coordinator and assistant special teams coach. I am the varsity boys track and field coach.
