Christine Gehres

My name is Christine Gehres, and I have ”been part of” GSLW since 2003. I was glad to step in as principal when the need arose in 2016.I am a German native, and completed part of my university studies in Germany. I have also worked in Germany until I came to the US as an expatriate. I founded the Mommy & Me program with another mother in 2006. I have substitute taught most levels and have been the second grade teacher. More recently, I taught an adult beginner class.  I have had to learn the English language as a foreigner, and understand what GLSW students experience when learning German as a foreign language. I have also served on the GLSW board as Vice President before becoming involved as a teacher.
