Effective 1/5/2025, Sabina Ledda & Caroline de Reu will take over the BovenMaas baton from Founder Eric Smith.
Eric has spent 20 years building BovenMaas Prenataal with dedication and passion to become the prenatal screening ultrasound expertise center in the R’dam and The Hague region. Eric may slow down and enjoy a well-deserved retirement together with Marjet Commijs, his mainstay inside and outside BovenMaas Prenataal.
It is up to us and the BovenMaas team to continue his work with the same intentions. Eric and Marjet remain involved as our quality advisor.
We are looking forward to it!

We kindly request you:

- Do not take pictures or video. If the examination allows this, you will receive an ultrasound photo from the ultrasound technician after the examination.
