Géraldine, DPV Cave diving instructor - Mexico
Cave DPV instructor

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

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

Since her first dive, Geraldine has kept learning, training, and exploring for the sharpest possible skills and experience. She has accumulated experience in each level of education she offers and always trains several steps ahead.

Geraldine likes to offer the best experience possible, the safest and most respectful for the environment. To be flexible, she only offers private guiding and adjust the schedule to avoid crowds to know you better and share our knowledge better. 

Geraldine manages to continue with her cave exploration projects… So diving with Deep Dark Diving is not only about getting private guiding and tailored service. It also supports cave exploration and conservation projects.
