Annette Barrada
Lead Teacher
​
Hallo und Guten Tag, my name is Annette and I am a German native.
I have been working with children ages 3 to 6 in a preschool setting since 1998 and teach German to preschool students at the German Texan Heritage Society in Austin since 2006. For 7 years, I worked in a Special-Education classroom for Pflugerville ISD with children of different ages and various disabilities.
I am a mother of two bilingually raised children who are all grown up now. I get to relive the experience of when they were little by giving my love to the toddlers and children that I take care of.
I am excited to teach the German Pre-school class at the German International School of Texas at Austin.


Bradley Barr
GTHS Academic Director
I have been teaching German classes to all ages with GTHS since 2011, and I’ve worked as the Academic Director since 2019. I was born in Austin, and besides the few words my grandparents taught me as a kid, I began learning German at Westlake High School. I completed my master’s degree in German studies in 2014 at the University of Kentucky. I’ve taught as a middle school German teacher, currently also teach German classes at Austin Community College.
I’m grateful to be a part of the great team behind the German International School, and look forward to working together with the community to grow and develop the school.
