As the founder of Freediving Moorea, Marine has been passionate about the ocean for as long as she can remember. A former world champion in monofin and a qualified sports educator, she has built her journey around the water, movement and sharing knowledge.

A Breton mermaid with deep roots, she draws her love of the sea from her family history. To her, the ocean is much more than a playground. It is a place of connection, calm and freedom.

After founding and developing her first freediving school in Lanzarote for four years, she chose Moorea as the next place to share her vision of freediving: a gentle, accessible approach centred on awareness and sensation.

Although she no longer lives in Moorea year-round, Marine remains at the heart of Freediving Moorea and continues to share its spirit through her courses, training sessions and team.

Raised by the Atlantic waves of southwestern France, Arthur developed a deep connection with the ocean from an early age. The sea became his refuge.

A qualified sports educator, he developed his freediving practice internationally before spending three years refining his skills at Bluenery Academy in the Mediterranean, alongside Guillaume Néry, former world champion. There, he developed a gentle teaching approach that makes freediving accessible to everyone, while gaining the technical expertise required to support experienced freedivers.

For Arthur, freediving goes far beyond athletic performance. Above all, it is a way to connect with yourself, an invitation to let go and listen to your sensations. He believes in a mindful approach where the water becomes a space outside of time, a place to slow down and reconnect with yourself.

His teaching is built around this balance: guiding each person towards greater technical skill while creating an experience of calm, freedom and inner connection.

Passionate about the ocean and the life within it, Sébastien has worked in the marine world for more than 10 years as a scuba diving instructor.

Naturally drawn to freediving for its meditative and calming qualities, he has developed an approach centred on well-being, relaxation and awareness of sensations. His goal is to help you discover a simple, enjoyable form of freediving, deeply connected to the present moment.

A spearfisherman for more than 10 years, he has developed an in-depth knowledge of the marine environment, particularly in the Tuamotus, where he lived aboard his sailboat. This experience has given him a unique understanding of the ocean and its marine life.

Trained as an AIDA and PADI instructor by Marine Grosjean and Julien Barbagallo’s freediving school, he now shares his passion with simplicity, enthusiasm and a thoughtful approach.
