About Lily Crespy


Freediving is such a singular sport, relying in huge majority on the mind. During the last twelve years working full-time as a freediving coach, my approach has always been to work on technique of course, but also heavily based on empathy, deep listening, doing the detective work to understand the mental blocks stopping the progression and finding the right keys and tools to unlock them.

I absolutely love helping people achieve their goals, reach their full potential, witnessing their breakthroughs and sharing the journey with them.

I am committed to bringing you all the tools, knowledge and experience I have acquired over the years, to help you improve your freediving skills and enjoy your dives to the fullest.
