Additional Info

I’m a cave diving instructor, technical diving educator, and lifelong student of the underwater world. Over the past two decades, I’ve spent thousands of hours exploring and teaching in some of the most demanding environments on the planet—from deep caves in Florida and Mexico to remote wrecks and advanced technical dives around the globe.

My background includes extensive experience teaching a range of technical and overhead environment courses. But today, I’m proud to dedicate my time exclusively to teaching Global Underwater Explorers (GUE) classes. I believe deeply in GUE’s commitment to high training standards, team-based diving, and a holistic approach that emphasizes skill, awareness, and conservation. Transitioning to teaching GUE full-time has allowed me to focus on delivering consistent, high-quality instruction within a system I trust and respect.

Cave diving, for me, is about precision, mindset, and continuous growth. I’m passionate about helping divers reach their full potential, and I take pride in mentoring students who want to dive with purpose, discipline, and a long-term perspective.

​

Whether you're just starting to explore technical diving or looking to refine your skills in a GUE framework, my goal is to support your journey with clarity, honesty, and real-world experience.
