DPV Geraldine
Cave DPV instructor

Born in France with a Ph.D. in Environmental Chemistry, I plunged into diving and became a Cave and tech diving instructor in Mexico.

I started cave diving when I first arrived in Mexico in 2010. A passion was born, and along with it, a passion for sharing my love for the underwater world with students.

Geraldine - Sidewinder CCR

Since my first dive, I keep learning, training, and exploring to be the sharpest possible skills and experience. I have been cumulating experience in each level of education. I offer and always train one step ahead.

Cave Diving - France

I like to offer the best experience possible, in the safest and most respectful for the environment way. To be flexible, I only do private guiding and adjust my schedule to avoid crowds. I get to know you better and share my knowledge better. 

During my free time, I manage to go on with my cave exploration projects… So diving with Deep Dark Diving is not only about getting private guiding and tailored service. It is also supporting cave exploration and cave conservation projects.

Who is “us” at Deep Dark Diving?

As independent technical instructors, cave, and cavern guides, we like to work together.
