Welcome to the 2022-2023 school year! 

 

I teach primarily 11th and 12th grade students. From the class periods I have listed, I teach Anatomy and Physiology, AP Chemistry, and AP Biology. This is my FIFTH year teaching - all of which have been at McKinley and SLPS!!!

 

For my students and parents, please email me. It is the best, most efficient way to reach me. I do not have a phone in my room. My address is: Jason.kesselring@slps.org 

 

I assure you, I will respond promptly!

 

As a former pediatrician, I bring a lot of practical knowledge about science (and a few other things!) to the classroom. One of the best parts about teaching is helping students realize that science isn't as complicated as they think. I think the beautiful thing about the subjects that I teach is that students can learn how to think broadly AND in a logical, ordered manner at the same time. Once students get the swing of it, the world really opens up - and that kind of approach is applicable to a great many things beyond science!

 

My wife (Sonia) and I have been married since June 2000. We have two children - a 17 year old son and a 14 year old daughter. We have 3 pets - 1 guinea pig, a 20 year old rescue conure (I really, REALLY like birds), and a dog. Outside of the classroom, hobbies include hiking (go outside and play!), running, and cooking.
