Géraldine, DPV Cave diving instructor - Mexico
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.

Since my first dive, I have kept learning, training, and exploring to have the sharpest possible skills and experience. I have accumulated experience in each level of education I offer and always train several steps ahead.

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

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.
