Mrs. Sarah Castillo

I am so excited to be your teacher at Cibolo Green Elementary School! Home of the Champions! 
This will be my 20th year teaching. I am a graduate of Southwest Texas State. Go Bobcats! I find great joy in providing a fun and loving environment for the students in my classroom and creating opportunities for them to become leaders.  

My husband Mark and I are native San Antonions.  We have a handsome 15-year old boy, a sweet 11-year old little girl and 6 year old boy/girl twins.  We also have a furry family member, a boxer named Roxy. My favorite past times are relaxing with my family, scrapbooking, and shopping.  I look forward to a fantastic year at Cibolo Green with a great group of champions.
