Sandra Castillon

Hello! My name is Sandra Castillon and I am a dual-language kindergarten teacher. I have been teaching since 1995 and I love what I do! I received my Bachelor of Science degree from the University of Houston in 1995. Following graduation, I began my teaching career for Galena Park ISD in Galena Park, Texas.

I've taught pre-kinder, kinder, second and third grade. In 2007, I returned to the University of Houston and earned my Master of Education degree. Go Coogs! In 2014, my family and I moved to Uvalde. I have two grown sons, Christian and Erik, who are studying here locally at SWTJC.  Uvalde has always been home for me, and I am excited to be part of this flagship school, Uvalde Dual Language Academy (UDLA).  The dual language program at UDLA will provide immesurable opportunities for our students and it will be an asset, I am certain, for our small rural community. 

I look forward to meeting and working with each and everyone of you! If you should ever need to reach me, please email me at: or call the school to leave me a message.
