Mr. Dennis Johnson

I am very excited about starting my 2nd year teaching at Reagan HS.  Although this is my 1st teaching assignment, I am no stranger to the classroom or the content.  I have tutored all levels of Mathematics at Northeast Lakeview College since 2016.  I am a recent graduate from UTSA, Go Roadrunners! And I am working towards my Master's Degree in Applied Mathematics.  I am currently a Blackhawk Medevac Pilot in the Texas Army National Guard.  I was deployed to Iraq for all of 22-23 school year, and I returned in May 2023. Feel free to ask me questions about that.

I was born and raised right here on Texas soil.  I have a beautiful wife who is a graduate of NEISD and 3 boys who also attend NEISD schools.  And 1 daughter who turns 1 this year!

I want you to know that I have your best interest in mind.  I am here for you if you need anything.  And I will have your back to the utmost of my abilities.  I look forward to working with each and every one of you, and your parents to ensure you are set up for success.  Let's learn some math and grow together!  Strike 'Em Rattlers!!!
