Catena is the registered association of the alumni of the Hermann-Josef-college, Steinfeld.
It was founded in 1981 and is registered under the number VR357 at the district court Schleiden (Gemünd). The association has taken on the task, on the one hand to support the provider of the school and boarding ideally and materially, on the other hand to strengthen and to foster the inter-class communication of students among themselves. The members of the Catena want to express their solidarity with the school and the boarding school beyond the time of their own school attendance. Catena is not only a chain of alumni themselves, but also always a link to the Hermann-Josef-College Kloster Steinfeld.
