Moving to the netherlands looking for a good gastroenterologist close to Leiden

I'll be moving from Belgium to the Netherlands for a new job in a few months, so i'm trying to get everything in order.

I have some stomach issues for which i've been getting yearly checkups in UZLeuven. Because i'll be switching to a Dutch health insurance i'll have to find a new provider. Anyone familiar with the gastroenterologists in the surroundings of Leiden? I've had some bad experiences with docs before so I am hoping i won't have to trial and error my way in this country as well.
