WELCOME

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 in 2022 we welcomed Han. Currently we are with four 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 122, 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!

Tetanus, diphtheria, and pertussis booster vaccine

 

As a practice, we would like to remind you to check your vaccination status for tetanus, diphtheria, and pertussis. This is a combination vaccine that must be repeated once every 10 years to remain adequately protected.

You can check your recent vaccinations via mijngezondheid.be.

You can make an appointment at the practice for this.

Job vacancy: practice nurse

 

We are still looking for a practice nurse to support our practice. As a practice nurse, you will monitor the practice's patients together with the GP, perform medical procedures, and be responsible for following up on medical files. The daily schedule and working hours are flexible and certainly negotiable.

Are you or do you know someone who works as a nurse or has studied nursing and is looking for a new challenge? If so, please feel free to send an email with a short motivation letter and your resume to: huisartsenpraktijkdetandem@gmail.com

Travel vaccinations


Would you like to review your vaccinations before you leave on your trip? Or do you need specific vaccinations before your departure? In this case, we ask you to always make an appointment for this. During the appointment, your trip and the recommended vaccinations will be mapped out, after which you will be given the prescriptions to purchase them. The vaccines will be administered during a follow-up appointment.

 

Kind regards,

Team The Tandem

Dear patient,

 

In order to remain easily reachable on a daily basis, we divide telephone traffic into two moments.

The reception is available daily from 08:15 to 10:30 . This telephone moment is intended for administrative questions, such as changing your appointment or adjusting your personal data. Medical questions will not be handeled here. 

 

We also have a weekly phone schedule where you will always get a specific doctor on the line, so you can speak to the doctor you want to reach (see schedule below). This phone hour is daily from 2 p.m. to 2:30 p.m. We emphasize again that this telephone hour is for general information. For results of examinations, we will call you back or you should make an appointment to discuss. Only for emergencies you can always reach us on the telephone number 0486/78 65 87.
