Tyler Hollow
Welcome to Mr. Tyler Hollow’s class!
I am a science teacher at Helena High School and my goal is for students to think like scientists and do what scientists do. I have taught over twenty years in many different science subjects including Earth and Space, Biology, Biomed 4, Chemistry, Wildlife Biology, AP Research and Horticulture. I am passionate about science and I enjoy exploring the amazing natural phenomena in Montana, especially rivers and mountain ranges and seeing wild things in wild places.
I grew up in Helena and went to college at Seattle Pacific University for my first year and finished my undergraduate degree at The College of Idaho. I earned a Bachelor of Science in Biology with a Natural Science Teaching Minor and played varsity soccer and ski raced. After graduation, I worked professionally in the northwest as a Fish Technician, Wolf Biologist, a wildlife guide, and as an environmental consultant. Additionally, I have taught High School Science in Meridian, Idaho and Victor, Montana. I graduated with a Masters in Science Teaching from Montana State University in 2018.
My wife and I have two children that are in the Helena Public Schools which I am proud to be a apart of. I enjoy the outdoors through trail running, river rafting, biking and all types of skiing. I also spend time coaching youth sports.
