Miri Wanis, Medical doctor

My name is Miri Wanis. I trained as a pediatrician in Syria and Armenia, and graduated in 2003. I returned to Syria where I worked in various children’s outpatient clinics. Unfortunately, I had to move to the Netherlands because of the bad security conditions there.

I have been living in the Netherlands for six years now. My qualifications are not valid here, so I had to retrain. I learned the Dutch language at Leiden University Language center and after that I took my medical exams. I completed my studies doing my internships at LUMC. I am BIG-registered now and allowed to work as a medical doctor here.

A medical doctor has to be a good listener in order to diagnose and treat patients, and give patients time to find words for what they need to say. That’s the main aspect of my work as a doctor.

It is nice to be on the B12 Institute staff and help B12 deficiency patients in the best way possible.

I wish you health and peace!

Kind regards,

Miri Wanis
