Due to a technical problem, we temporarily can't be reached by phone.



Who are we?

In 2013, as two college friends (Sylke and Hannah), we started the practice De Tandem in the heart of Laken. In 2018, we welcomed our third colleague Willem and currently we are with three permanent doctors and a GP-in-training. We live and work in Brussels and feel at home in the fascinating mix of cultures, languages and people.

The Tandem stands for the doctor-patient relationship: we hope, as doctors, to cycle in the same direction as the patient and to arrive at a good approach, in mutual consultation. The road will not always be flat and straight, but detours, hills and valleys also form a beautiful landscape. Taking time for each person is important to us. In the Tandem, we are a team: the patients are known by the practice and there is regular consultation, in which we base ourselves on the current guidelines (evidence-based medicine).  

Our mother tongue is Dutch and we are also fluent in French and English. You can come to us with any health-related questions or problems. We provide both acute and chronic care to everyone between the ages of 0 and 22, regardless of culture, background, gender or philosophy of life; we assist with pregnancies, we care for people in the last phase of life, we see young children, mothers & fathers, singles, the elderly, young people, travellers, pensioners, refugees, artists, civil servants, the self-employed, ... in other words, everyone.

The enthusiasm has continued to grow into a dream where we can work together with care providers from other disciplines under one roof. And that is how BLES came into being in 2021. We hope to continue working together on good, high-quality care for every Brussels resident, with a broad perspective on health and well-being.

Welcome to De Tandem!


Changing address

We are very pleased to announce that we will be moving soon! As of March 1st, De Tandem will be located at Pannenhuisstraat 46, 1020 Laken. This is about 300 meters from the current practice and just as far from the Pannenhuis metro.

We are moving to a larger location where we will be working together with other health care workers such as physiotherapists, psychologists, a career coach and a midwife.

In the beginning it will take some time getting used to this new situation, so we ask for your understanding for the possible inconveniences caused by the move. The online agenda and telephone number remain the same.

Important: the practice will be closed on Thursday and Friday 25 and 26/02! We can only be reached by phone on the emergency number 0486/786587. We will help you as much as possible by phone or mail.

Dr. Gilles Depuydt, junior doctor


It is our pleasure to introduce to you our new GP junior doctor, Dr. Depuydt!

You can make an appointment with him via the online agenda.

I am a young GP in training for whom the patient as a person is always at the center of every consultation. By cooperating in an active and continuous way with the other doctors in the practice I hope to refine my own skills and to offer optimal care to the patients. Together, we form a team to serve all of your health care needs. I have gained medical experience and experience in the humanitarian field both at home and abroad, and have always enjoyed serving the local community. I have worked in hospitals and surgeries from Belgium to Paraguay, provided humanitarian aid to refugees in Calais and Brussels, and been the (head) leader of the local youth movement at my home town. Out of office hours I am a great music fan who can always be found for tips and musical discoveries!
