Tyler Hollow

Welcome to Mr. Tyler Hollow’s class!

I am very excited for my tenth year at Helena High School. I really enjoy the students at Helena High School and appreciate their willingness to work hard and be involved. I grew up in Helena then moved to Idaho and attended The College of Idaho and earned a Biology degree. After graduation I worked professionally in the Northwest as a Fish Technician, Wolf Biologist, a wildlife guide, and as an environmental consultant. I have taught Science to High School students in Meridian, Idaho and Victor, Montana. I recently graduated with a Masters in Science Teaching from Montana State University.

I teach Biology, Biomed 4, and AP Research. Biomed 4 is an upper level research class in the Health Career Pathway while AP Research is an elective credit and one of two classes in AP Capstone. I am passionate about science and research, and excited to work with students in Science Technology Engineering and Math (STEM) fields.
