Mr. Alex Castaneda

I am a Board Certified Nurse Practitioner with a passion for teaching.  Health science is where chemistry, physics, and biology all come together and we see how the human body constantly compensates for different stresses in attempt to heal itself.  I grew up in Long Island, New York but have been living here in San Antonio for the past 22 years.  I have a beautiful wife Gina, who teaches health science at LEE HS, an amazing son Christian (10 yrs old), and a crazy dog - Carson.  We love all-things robotics and over-the-summer, I attained my 34th solo win in Fortnite (my son only has 5 solo wins) - yes, I'm the man! 

Treating and helping people is both an honor and a privilege.  My goals as your teacher are to: 1) Stimulate your imagination and passion for learning. 2) Inspire and motivate you to realize your potential is much greater than you believe. 3) Broaden your view of health care - it is a broad field and you have many options, and 4) Help you attain your goals in health care.
