After attending a number of this organization's events over the years, it's been on my list to join (finally) Zeitgeist NW as a business member. DONE!
This group brings not only prominent Kulturmacher to Portland (Katja Riemann, Armin Mueller-Stahl!) but also pieces of culture that are reflective of the Germany that exists today. Ex-pats can easily lose touch with a home culture as the years wear on.
They don't stop at just the remarkable German Film Festival or the monthly film series, you can also attend a talk on other topics. A recent favorite was the Passivhaus ... the net zero house design where just a tea light or two would be enough to heat the home.
This committed and inclusive group intelligently urges those who have not lived in Germany for years or decades to take a step back and see the changes. And for those new to German culture, they expand the vision beyond Lederhosen and Gartenzwerge. If you are local to Portland, I encourage you to join the organization.
