upsidedownHi, I’m Chris, the owner of Technical Diving Services. I started diving in the Netherlands years ago and I just  love to be in or underwater. I went to Bonaire on holiday several times, and at a certain moment I decided to stay. I have been living on this beautiful island since 2004. Diving and teaching is my passion whether it is a guided dive, an Open Water Diver course, continuing education program or specialty (SDI/TDI), a course with physically or mentally disabled persons (IAHD) or a TEC course or dive, I’m your man! On top of that I’m Instructor Trainer for SDI/TDI and IAHD.

Hi, I’m Astrid, the co-owner of Technical Diving Services In a former life, I used to be a musicologist, writer, and editor. I took a short break to become a divemaster on Bonaire, and totally fell in love with the island and the underwater world. So shortly after I became a PADI instructor, and after gaining some teaching experience down under and above, I became an IAHD instructor and a SDI Instructor Trainer. But you’ll find I enjoy a Discover Scuba Dive just as much as training new professionals.


Sven van Everdink

My name is Sven and I’m PADI and TDI Instructor. Most of the time I teach in the dark and cold waters of the Netherlands, in which I love to dive. I consider it a challenge for my students and myself to train in these conditions and I believe people can become a better diver this way.

Although I fell in love with the Dutch waters, Bonaire is my second home. I have lived in this beautiful island for three years, working fulltime as a diving instructor. So it’s no surprise that once in a while I drop by on this amazing place. When I’m on Bonaire there is a good change you’ll find me at TDS helping out however I can. From teaching technical diving to bring you a cup of coffee.

Although I don’t literally work for NDNL or TDS, you’ll often find me hanging out and practicing my coffee making skills. On top of that I recently finished my SDI Assistant Instructor internship.
