Mr. Chad Castillo


This is my fourth year at CDO and ninth as an educator in Tucson.  I am a life long Tucsonan having graduated from Salpointe in 2002, and the U of A in 2007. I have an awesome nurse practitioner wife and 2 kids under the age of 6, with a third on the way!  I'm also a club swim coach for FORD aquatics.  I'm inspired every year by the amazing students at CDO and I am looking forward to another great year.

Core beliefs

I believe that the ability to think scientifically is one of the most benificial skills to have.  Helping students practice the skill and understand how to use it in their life drives my teaching style.  It's also pretty cool to blow stuff up :)



I have been a high school swim coach since I was 19 years old.
