Train with Martijn
from beginner to instructor — and beyond.
I’m based on Bonaire and I teach the full range: beginner courses, specialties, professional development, technical diving, Trimix and CCR — including instructor-level Tec and Trimix pathways. Calm coaching, strong fundamentals, and real-world diving habits.
Who I am
Instructor first. Coach always.
My focus is simple: build divers who are calm, capable and aware — at any level. From your first certifications to serious mixed-gas and CCR training, fundamentals scale.
- Clear explanations, clean demonstrations and coaching that sticks.
- High standards, low ego — and a lot of time in the water.
- Training built around your goals, your schedule and your pace.
- Professional development with real-world habits (not just “passing”).
What I teach
Training from beginner to professional.
Start from zero, level up with specialties, or go pro. I teach the full progression and can build a pathway that fits your timeline.
