Tyler Hollow

Welcome to Mr. Tyler Hollow’s class!

I am very excited for my ninth 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. I attended the College of Idaho and earned a Biology degree, then I worked in Idaho, Wyoming and Victor, Montana before moving back to my hometown. I recently graduated with a Masters in Science Teaching from Montana State University.

I teach Earth Science and Biomed 4. Biomed 4 is an upper level research class in Health Career Pathway. They are both laboratory-based and focused on the process of science. I am passionate about science and excited to work with students in Science Technology Engineering and Math (STEM) fields. Students will be thinking like Scientists and doing Scientific work every day.

For Biomed 4 student’s class material can be found on the LMS link.
