Founder of Freediving Moorea, Marine has been passionate about the ocean for as long as she can remember. A former monofin world champion and sports coach, she has built her path around water, movement, and sharing her knowledge.

A “Breton mermaid” with deep roots, her love for the sea comes from her family history. For her, the ocean is much more than a playground — it’s a space for connection, calm, and freedom.

After founding and running her first freediving school in Lanzarote for four years, she chose Moorea to continue sharing her vision of freediving: a gentle, accessible approach focused on sensations.

Today, even though she is no longer based there full-time, she remains the creator of Freediving Moorea and continues to bring its spirit to life through her retreats, trainings, and team.

Rocked by the Atlantic swells of Southwest France, Arthur developed a deep connection to the ocean, his refuge, from a very young age.

A qualified sports instructor, he honed his freediving practice internationally before refining it over three years at the Bluenery Academy, in the Mediterranean. Alongside Guillaume Néry, former world champion, he helped shape a teaching approach that makes freediving accessible to everyone, while acquiring the technical expertise required by advanced freedivers.

For Arthur, freediving goes beyond mere athletic performance. It is, above all, a way of meeting oneself, an invitation to let go and tune into one's sensations. He favors a sensitive, mindful approach, where the water becomes a timeless space in which to find one's center. His teaching rests on this balance: guiding students toward technique while offering each person an experience of calm, freedom, and inner connection.

Passionate about the ocean and everything that lives within it, Sébastien has been working in the marine world for over 10 years as a scuba diving instructor.

Naturally drawn to freediving for its meditative and calming side, he develops an approach focused on well-being, relaxation, and sensations. His goal: to help you experience freediving in a simple, enjoyable way, deeply connected to the present moment.

A spearfisher for over 10 years, he has developed a deep understanding of the marine environment, especially in the Tuamotu, where he lived aboard his sailboat. An experience that gives him a unique perspective on the ocean and marine life.

Trained as an AIDA and PADI instructor by Marine Grosjean and the freediving school of Julien Barbagallo, he now shares his passion with simplicity, precision, and authenticity.
