I have been working with Caroline Sieveking since my first exhibition, »Seelenkind« for the Diözesanmuseum. Since then we have produced many catalogs together, always open, of high quality and with very special results. Working with her and her excellent team is always a lot of fun.

Christoph Kürzeder

Director Diözesanmuseum Freising

We have been working successfully with the Sieveking agency for more than 30 years. Today, they design all our teaching materials, whether print or digital. We have built up a great partnership with Ms. Sieveking and her competent, committed staff, which has become increasingly intensive, successful and familiar over the many years of working together. This allows us to concentrate fully on our core business, the content and distribution of language textbooks worldwide.

Michaela Hueber

Head of Hueber Publishing

I want to tell you how much we love the Guston Drawings catalogue. We appreciate the attention and personal commitment you made to the project – the exceptional standard you aimed for is very evident. Hair-raising as some of the deadlines were and despite the added problem of working long distance, we thoroughly enjoy cooperating with your outstanding team and I congratulate everybody involved.
