My journey
I am a passionate freediving instructor and travel expert who has transformed my love for underwater exploration into a professional practice. As a certified Molchanovs Wave2 Freediving Instructor, I bring knowledge and experience to my teaching, whether in Switzerland's lakes or international waters.
My freediving journey began in 2022, quickly evolving from personal passion to professional calling. My approach combines technical precision with mindful awareness, helping students develop both proper techniques and the mental focus essential for this unique sport.
I've traveled across the world to teach freediving and have worked for the world's biggest freediving event, gaining invaluable experience that I bring to all my instruction. As a multilingual instructor (DE, ES, EN), I connect with diverse students from around the globe. Beyond local teaching in Switzerland, I organize specialized retreats in various international destinations, creating immersive freediving experiences that blend skills development with cultural exploration.
Through deepserenity.ch, I've established a community of freediving enthusiasts who share my passion for underwater discovery. My teaching philosophy centers on making freediving accessible to everyone—from beginners taking their first breath-hold to advanced practitioners refining their techniques.
