Management of the iDSB
School Board
Procolino Antacido has been headteacher of the International German School in Brussels since 1 August 2026. He teaches German, history and Protestant religious education.
Before joining the iDSB, he gained experience at schools both in Germany and abroad: from 2015 to 2021, he was Head of the German School in New Delhi, India, and from 2004 to 2009, he was Head of German-language Subject Teaching and PQM Coordinator at the Colegio Humboldt, the German School in São Paulo, Brazil. In 1998, he worked at the German Embassy School in Riyadh, Saudi Arabia.
In Germany, he worked in Taunusstein and Frankfurt am Main, where he held the posts of Head of Studies, Head of Department and Headteacher.
Most recently, he was headteacher of the bilingual Freiherr-vom-Stein-Schule, a grammar school in the city of Frankfurt am Main which awards the dual qualifications of the Abitur and the Italian Maturità.
As a committed European, he looks forward to working with everyone involved in school life to further develop the iDSB in times of changing societal demands. Transparency and participation are his guiding principles in this regard.
Rolf Linse has been a member of the teaching staff since 2020 and initially headed the lower secondary school until July 2024. He has been deputy headteacher since the 2024/25 academic year. Last academic year, he also served as acting headteacher. Mr Linse teaches German, French, Spanish, History and swimming at our school and is also qualified to teach Italian.
Before joining the iDSB, he gained experience at general and vocational schools in Germany and France, as well as at the German International School of Silicon Valley in California.
Most recently, Mr Linse worked at the Wirtemberg Gymnasium in Stuttgart, an elite school specialising in sport and football, which enables young elite athletes to combine their schooling with high-performance sport.
It is particularly important to Mr Linse to focus his work not on his subjects, but on his pupils, and to help them grow into responsible, tolerant and open-minded individuals, whilst finding their own path in life. As a committed European and cosmopolitan, he is particularly delighted to be taking on this role in the capital of Europe.
Petra van den Beukel has worked in the administration since 2004 and is responsible for Human Resources and Internal Services (including the canteen). Since 2018, she has been entrusted with the management of all administrative business. Before coming to Brussels, Ms van den Beukel worked for many years in the marketing for various large companies in Frankfurt am Main. After 16 years at a school, she can identify very well with the words of A. Lindgren A. Lindgren: “There is no age in which everything is experienced as much as in childhood. We adults should remember what that was like.” Ms van den Beukel is supported by experienced staff in the areas of marketing, finance, personnel, secretariat in KiBi/GS and OS as well as school catering for Bistro & Mensa and facility management.
Extended School Board
Emanuel Imfeld has been headteacher of the iDSB Primary School since the 2024/25 school year. From 2019 to 2024, he served as deputy headteacher there and was responsible, amongst other things, for timetable and supply teacher planning. Alongside his management duties, he consistently served as a class teacher and taught the core subjects of mathematics, German and general studies in Years 1 to 4, as well as acting as a subject teacher for music, PE, religious education and English.
His career at primary schools in Switzerland, Germany and South Africa, as well as his leadership experience at a bilingual Montessori nursery and as deputy headteacher of a primary school, have had a lasting influence on his educational and organisational work. His approach to leadership is based on the principles of ‘New Authority’. He strengthens relationships rather than exercising power, provides guidance through his presence, and works together with children, teachers and parents to develop a school community characterised by trust, responsibility and mutual support. Psychological safety forms the foundation for independent thinking, effective teaching and an active partnership in education.

Marina Falcone has been the deputy primary school principal since the 2024/25 school year. Since joining the iDSB in 2020, she has worked as a subject and class teacher in the primary school.
Before her time at iDSB, she gained valuable experience at a primary and secondary school, where she not only worked as a class teacher and contributed to various career orientation projects but also provided advisory support in the areas of inclusion and digitalization. Simultaneously, she led the subject didactics seminar for geography at a teacher training college, where she trained aspiring teachers.
A central aspect of her daily work is promoting the European spirit while fostering social and intercultural competencies.
In April 2026, Sarah Klempin took over as head of the Bilingual Kindergarten and Pre-school. Prior to this, she had been working in various international settings since 2016, including in Istanbul, Riga and Izmir. There, she gained a wide range of experience in early years education, primary education and in the field of German as a foreign and second language. Most recently, she served as head of the kindergarten at the German School in Izmir.
Thanks to her many years of work abroad, Ms Klempin has extensive experience in dealing with interculturalism, multilingualism and different education systems. These perspectives shape her pedagogical approach and her leadership style.
The focus of her work is on the holistic support and guidance of the children. Working closely with the teaching team, the families and the children themselves, she shapes the nursery into a place where everyone involved feels seen and valued. The aim is to create an environment that sparks curiosity, enables development and offers space for individual growth.
Since the 2026/27 academic year, Ms Nagel has been headteacher of the iDSB Technical College and teaches German and Economics. Prior to this, she spent many years teaching at a vocational school in the Frankfurt area and most recently worked for two years at the Hessian Ministry of Culture, Education and Opportunities.
She has a special personal connection to Brussels and the iDSB: her parents worked at the school some 20 years ago, her sister obtained her Fachhochschulreife here, and she herself first became acquainted with the iDSB during an internship whilst she was a student. She is therefore particularly delighted that her own career path has now led her back to Brussels and to the iDSB.
In her new role, she is looking forward to further developing the technical college, building on tried-and-tested practices whilst also introducing new ideas – and, above all, supporting our pupils on their journey towards their technical college entrance qualification.
Lena Wullers has been a member of the teaching staff at iDSB since 2023 and will take over as headteacher of the Realschule from the 2026/27 school year. She teaches mathematics, PE and Catholic religious education.
She gained professional experience in Schleswig-Holstein and Lower Saxony, amongst other places, where she also taught final-year classes at Hauptschule and Realschule.
Her teaching focuses on the pupils and their individual strengths, needs and potential for development. Building a relationship based on trust, engaging in respectful dialogue and providing reliable support during this special stage of their lives are central to her approach.
Lena Wullers regards the iDSB Realschule as a successful model in its own right: small class sizes enable individual support, whilst practice-oriented learning specifically prepares young people for their future educational and personal paths. Together with the teaching staff, she aims to further develop the Realschule and ensure it remains a reliable, personalised and forward-looking place of learning for pupils and their families.
Mark Osterland has been working at the iDSB since September 2024. He is head of the upper secondary school.
Dorothea Esten has been working as the middle school coordinator at the iSDB since August 2026 and teaches German and chemistry. Prior to this, she spent many years as head of the upper school and head of vocational training at a bilingual AbiBac grammar school in Andernach (Rhineland-Palatinate). This is her first post at a German school abroad.
In her work, she attaches particular importance not only to imparting knowledge to young people, but also to fostering tolerance and an open-minded attitude towards the world. However, in light of the global changes of recent years, an appreciation of nature and a clear understanding of democracy are also becoming increasingly important – and there is hardly a better school for this than the iDSB Brussels, situated in the heart of Europe.
Matthias Verdoodt has been working as a Dutch teacher at the iDSB since 2018. He has strengthened the extended school management as coordinator since September 2023 and is interested in languages and creative digitalised lesson design in his professional environment. What Verdoodt particularly likes here is that the work is very student-oriented. Children are not a number here, but a person whose qualities he wants to emphasise. Matthias Verdoodt hopes that he, as coordinator, can get the pupils to think outside the box and help them grow into critical, empathetic young people.
All-day coordination
Annette Farcy is responsible for all-day activities at the primary and secondary school since September 2024.
