    Julia passionately advocates for bilingual education. After graduating from LMU in Munich (M.A. in Theater + Pedagogy), it was her passion for acting that brought her to NYC. In 2014 she started teaching at the German School Brooklyn (GSB), where she transitioned from class teacher to administrator. In 2018 she helped to establish the German School Manhattan (GSM) and took on the role of director 2 years later. Being a school leader has given Julia the opportunity to mentor teachers and bring a creative approach to curriculum blending. Julia lives in Brooklyn with her daughter Lumi.
