My first memory of freediving dates back to 2014, when I was serving in the Marine Corps.
As a child, I was traumatized by a drowning incident, and the vast unknown of the ocean always intimidated me. However, during my marine training, I quickly broke through that fear and discovered a deep connection with the water.
After my military service, I decided to learn freediving formally and was instantly hooked.
Now, as a freediving instructor, I have the privilege of sharing this incredible experience with you.
I’ve trained hundreds of students from various countries in some of the best freediving locations, including Koh Tao, Thailand, Amed, Bali, and the top-notch freediving facilities in Korea. My goal is to make your first freediving journey both valuable and enjoyable.

The ocean has always been the place where I feel most at home.
Growing up in Gwangalli, Busan, I spent much of my childhood by the sea. I swam with my father, dove underwater to look for sea urchins, and collected beautiful stones to proudly show my parents. At the time, it was simply my favorite way to play. Looking back now, I realize the ocean had already become a part of who I am.
When I discovered freediving as an adult, it brought back the same excitement I had felt as a child. Holding my breath and exploring the underwater world in complete silence wasn't just another sport. It became a new way to connect with and truly appreciate the ocean.
That passion eventually led me to become a freediving instructor. Since then, I have had the opportunity to teach and dive with people in Korea and in beautiful waters around the world. The most rewarding part of my work is seeing someone overcome their fear of the water and discover the joy and freedom that the ocean can offer.
To me, freediving is not just about depth or performance. It is about building a connection with the ocean and learning to feel comfortable, confident, and relaxed in the water.
Whether it is your very first dive or the beginning of a new journey, my goal is to make your experience safe, enjoyable, and truly unforgettable.
