Marjon Koster-Zeestraten

Midwife, sonograper and specialist in external versions

My name is Marjon Koster-Zeestraten. In 2004 I graduated from the midwifery academy in Rotterdam. After my graduation I started working in a midwifery practice in Zoetermeer. I owned the practice together with my colleagues for 9 years with great pleasure. In 2013 there was a spot in Haarlem-Noord, a new challenge for me.

After my midwifery studies I was trained to do external versions. With an external version I try to turn the baby form a breech position to a normal position. We provide external versions with 5 colleagues in ultrasound centre the Schoot. Since 2008 I’m a sonographer, and since 2012 I’m also allowed to make the anomaly scan around week 20 of the pregnancy.

I work conscious, together with Janneke, in a small practice. Giving enough time and attention to you is very important to us. Together we prepare you for this special moment!

I’m mother of 3 children: Noud, Teun and Fien.

Janneke Mathijssen

Midwife and breastfeeding consultant IBCLC

My name is Janneke Mathijssen. When I was a child I already knew that I wanted to be a midwife. I gratuated at the academy for midwifery in Maastricht in 2016. I came to Haarlem-Noord to replace Marjon during her maternity leave. I decided to stay in the practice, and from the collaboration with Marjon our new practice Luna was born.

It is very special to support you from the early beginning of a pregnancy. The best thing for me about being a midwife is to deliver your baby. It’s an honor, every time I can be there. It’s wonderful to not only see a baby being born, but also to support the birth of new parents! I’m very happy to work in our own practice, with the best team and with the same vision on midwifery care.

I have also been trained and certified as a breastfeeding consultant IBCLC. I can offer you extra care regarding feeding your baby. Together with the breastfeeding consultants in Haarlem, we organize a mom-café at Brownies and Downies every three weeks.

I became mother of my daughter Luus in October 2020. What an experience! I’m very happy that I had a homebirth with the guidance of my colleague Marjon!

Anika Mesman


My name is Anika Mesman. I’m working for Luna almost from upon the beginning, with great pleasure! We’ll meet regularly during the pregnancy so I would like to introduce myself.

I was born and raised in the area of Haarlem and I’m very happy to work here now! As kid my fascination for pregnancy and birth has already arisen. My grandfather was a sheep-farmer and as a young girl I helped him delivering the lambs. After I got older my interest grew and soon I was sure: I wanted to become a midwife. Everytime it’s special to guide you through the pregnancy, delivery and post partum period. I love working in this small practice so we can get to know each other well so there’s enough space and attention to take care of you.



Monique is our assistant. She is at the practice on Monday-, Tuesday- and Thursdaymornings from 07.30-13.30 O’clock. She can answer a lot of your questions and schedule your appointments. We are always available for information or questions: so when Monique isn’t working, your call will be forwarded to the midwife on call.

Student midwife

The future of midwives is very important, that’s why we sometimes offer placements for student midwives.
We are trained to supervise midwifery students from the Academies for Midwifery in Maastricht and Amsterdam/Groningen.

Manon Binkhorst

From the 7th of June we’ll be guiding Manon Binkhorst for 5 weeks. She’s a first year midwifery student and will get her first experiences in our lovely profession.
