My journey

I am a passionate freediving instructor and travel expert who has transformed my love for underwater exploration into a professional practice spanning the globe. As a certified Molchanov's Wave 2 freediving instructor, I bring extensive knowledge and real-world experience to my teaching, whether in Switzerland's pristine lakes or international waters.

My freediving journey began in 2022, quickly evolving from personal passion to professional calling. I completed my instructor certifications in Mexico's breathtaking cenotes, joined the prestigious Molchanov's organization in Bali, and now work for the world's biggest freediving festival around the globe.


Global Experience & Media Recognition

I've been featured in two Swiss television reportages (scroll down) and have taught freediving across Switzerland, Bali, Thailand, Greece, Croatia, and Italy. My diving adventures have taken me to Mexico, French Polynesia, Australia, Indonesia, and various locations throughout Europe.


Learning from Champions

I've had the privilege of learning directly from world champion Alexey Molchanov, absorbing advanced techniques and the mental approaches that define elite performance. This exposure to world-class instruction continuously evolves my teaching methodology.


Teaching Philosophy

My approach combines technical precision with mindful awareness, helping students develop proper techniques and mental focus. As a multilingual instructor (Swiss German, German, Spanish, English), I make freediving accessible to everyone from beginners to advanced practitioners.

Through deepserenity.ch, I organize specialized international retreats and have established a thriving community of freediving enthusiasts who share my passion for underwater discovery.
