New Faces at the GESM

We'd like to introduce to you some new colleagues at the German European School Manila:

My name is Thomas Decker and I will be teaching History, English and Social Studies for the German section and the IB program, as well as German as a foreign language.

Before coming to GESM, I taught grades 5 to 12 at the German School in Dubai, UAE, including Abitur-level History.

I studied at Mannheim University and Albert-Ludwigs-University Freiburg im Breisgau.

I'm excited about the prospect of teaching at GESM.
