Mr. Castillo


Hello De Zavala Community! I am very excited to be part of De Zavala. My name is Guillermo Castillo. I have been a teacher for more than 20 years. Back in 1999, I became certified as a Bilingual teacher. I also have a technology application, ESL and Spanish certification. I attended the University of Saint Thomas where I became certified as a teacher.

“Every word makes you smarter ” This quote reflects my belief in education and the importance to achieve small victories every day in the classroom that lead to a big success at the end of the school year. Parents, teachers and students work every day in one single goal: to make you smarter! In recent years, I fell in love with teaching writing, so this school year we will be working to write words, sentences, paragraphs and ultimately a composition that is on topic and reflects your level of commitment in your learning. I want you to know that I will be here to help you be a better person, student and member of society, but this cannot be done without your help. Let’s work together make the  2021-2022 school year the best ever!

 Here are some important times during the school day:

1. Conference Time      9:50-1O:40

2. Lunch Time              11:10-11:40
