Treffpunkt is dedicated to the German-speaking residents of Arizona!  

We invite everyone to become a part of and learn more about German-speaking cultures.


The “Treffpunkt” (meeting place) is a nonprofit organization and meeting point for Germans, Austrians, Swiss, and everyone who speaks German - or anyone who would like to learn more about it.

Our sponsors and members contribute to diversity within the “Treffpunkt.”  We are closely associated with German businesses in Arizona, local German-speaking clubs, Arizona State University ('ASU'), and other universities/schools.


In addition to our educational objectives, we offer German foods, beer, and wine from German-speaking regions, German books, exhibitions, concerts, lectures, social meetings, and much more.


We welcome new members!!  


And we are happy to share more info. about all that we offer!
