How Seminars Work
The Detorakis Freediving Seminar Program offers live, interactive online sessions designed to complement and expand the knowledge presented throughout the platform’s training courses. While online courses allow you to learn at your own pace, seminars provide the opportunity to engage directly with the instructor, discuss specific topics in greater depth, ask questions, and gain practical insights based on real-world freediving experience. Seminars are intended for students who wish to deepen their understanding of freediving theory, physiology, training methodologies, safety practices, and many other specialized subjects. Unlike traditional recorded lessons, seminars are conducted live, allowing participants to interact, exchange ideas, and receive personalized guidance in a focused learning environment. All seminars take place online through Zoom and are available exclusively to active subscribers of Detorakis Freediving.

Owner & Instructor
Meet Yannis Detorakis
Yannis Detorakis experience in training freedivers and freediving instructors, exceeds 2,000 certified students, from 2001 to date! But his experience in freediver training spans 38 years, since 1988!
He certified hundreds of freedivers and freediving instructors, from 2016 to 2026, as one of the first PADI Freediver Instructor Trainers worldwide. Between 2017 and 2026 he was the Freediving Training Director at Spyros Kartelias PADI CDC Dive Center in Athens, Greece.
He certified more than 1,500 freedivers the years 2004 – 2016 as the first PADI Freediver Instructor in Greece, teaching his own designed PADI distinctive specialties, at his 5 Star PADI Diving Center “Atlantis Diving” in Athens, Greece. The Freediver courses he designed in 2004 were soon to become the official 3 levels in PADI freediver training (at 2016): Freediver, Advanced Freediver and Master Freediver.
Yannis has published a series of books and manuals about freediving since 1995. Some of them are unique in the world, like the biography of Stathis Hatzis, The Physiology of Freediving and the Equipment of Freediving. His books can be found printed in hard cover or as kindle e-books at all Amazon bookstores, in English and Greek editions.
