Degrees and Certifications:

Mr. Alex Castaneda

I am a Board Certified Nurse Practitioner with a passion for teaching.  Health Science Theory is where we build upon the foundations laid in Principles of Health Science.  We begin to learn skills such as transferring patients, as well as disease processes.    Health Science Theory is where chemistry, physics, and biology all come together and we see how they apply to the human body. 

I'm originally from New York but moved here "as fast as I could," and have been living here in San Antonio for the past 23 years.  I have a beautiful wife Gina, who teaches Health Science at LEE HS, an amazing son Christian (11 yrs old) who is starting the STEM at Nimitz Middle School.  We also have two dogs, Carson and Coco.  We love all things robotics, physics, and science!

Treating and helping people is both an honor and a privilege.  My goals as your teacher are to stimulate your imagination, ignite a passion for learning, inspire and motivate you to attain your goals in health care.
