My name is Coach Diehl, and I will be your Geometry teacher for the 2020-2021 school year. I am a proud graduate of Sam Houston State University. This is my first year at Tomball High School. Along with teaching, I will also be coaching Volleyball.

I am excited about the 2020-2021 school year and look forward to getting to know all of you this school year. My goal this year is to challenge you to not only learn more but take the knowledge you have gained and use it to make a lasting impact in society.

The best way to reach me is by email if you have any questions or concerns.
