Mr. Martenson

My name is Mr.Martenson, and I am from Mead, Colorado. I have been involved with sports in some shape or form since I can remember. I grew up playing football, baseball, and basketball and did so all throughout high school. I then pursued a degree in Physical Education at the University of Northern Colorado that would allow me to continue to be involved with these activities and help me give back like so many of the great teachers and coaches I had as a student who inspired me. 

In my free time, I love to watch sports and stay active and outdoors. I am a fan of the Denver Broncos, Nuggets, and Rockies but, have always been a big fan of Alabama football (Roll Tide!). If I am not inside watching sports odds are you will find me with a fishing pole in my hands exploring our great state!

This will be my first year teaching at Greeley West High School and I am excited to join such a close tight-knit community. I will be teaching field and court, freshmen physical education, as well as health. I will also be the head freshmen football coach and am excited for an awesome year!
