About Us

About Willem

I’m Willem Dekker, early retired Dutch Marine, and co-owner and Manager of Dive Sint Maarten. As the former Manager and Boat Captain of Octopus Diving SXM for nearly three years, I am very familiar with the dive industry on St Maarten. After being approached by Bobby’s Marina to take over Octopus Diving SXM, I was excited to accept the challenge to offer the same high-quality, professional service, but with my own personalized touch. I’m looking forward to welcoming you in Bobby’s Marina, close to the cruise facilities, same location but a new name: Dive Sint Maarten!

About Theo

I’m Theo van Groesen, PADI dive instructor, former employee of Octopus Diving and co-owner of Dive Sint Maarten. I have over eight years’ experience as a dive instructor worldwide, having worked in some of the world’s best dive spots including the Maldives, Australia, Thailand, Mexico, Nicaragua, Indonesia and of course Sint Maarten! Being fluent in four languages, I can guide you in not only English and Dutch, but also German and Spanish.

Above all else, I am passionate about delivering the very best experience to my guests and students, and introducing them to the spectacular underwater world of Sint Maarten in the safest and most enjoyable way. I look forward to diving with you soon!
