About Us


Our History

Tanja and George are founders of the Sea World Scuba Diving Center Kos. Their story is a love one – love toward the sea, environment, people and exploration. Their first meeting was in an underwater world and they knew from that moment that they should spread this love to others. With a mix of academic background and more than 25 years of experience, they see their job as an expiring task in a challenging world of climate change, sea-level rise and water pollution. Beside teaching scuba diving as a sport, they feel responsible for educating students to live in harmony with the ocean and giving examples of responsible divers. After 17 years of his first scuba diving center on Lesvos Island – Lesvos Scuba Oceanic Center, George, together with Tanja, decided to make a step further. They decided to join Sea World Diving Centers’ chain. This is how Sea World Scuba Diving Center Kos saw the light of the summer sun. After just 2 years of operation they received 129 of 5 start reviews and just 1 with 4 stars on TripAdvisor, which are proof of professionalism of the staff and proper management. They feel blessed that people recognize their effort of bringing the best possible service for them.

My passion for diving began 7 years ago when I resolved to quit my comfortable “9 to 17” job and decide to travel to South East Asia. Not knowing it would be a one-way ticket!
Since then, I have been traveling, around the globe, while teaching courses in French, English, Portuguese and Spanish.

OWS Instructor

As a child and teenager growing up in one of the most cosmopolitan and busiest capital in Europe, for me the best time of the year was always when the summer holidays were around the corner, the best and most exciting times because every year without failing I was lucky enough to travel and spend two full months by the shores of the Atlantic ocean in Portugal, where the sound of the waves was music to my ears, the power of the tides was energy for my body and mind and naturally made me fall in love with the seas and whole nature.
By the ocean, I did it all! spending countless hours playing in waves and sand, from snorkeling, swimming, bodyboarding, surfing, camping, endless walks with my feet in the Asiawater and so much more.
In my adulthood the corporate world took the best of me until 2015 when during a trip to southeast Asia I tried for the first time scuba diving, that was the moment when I went back to being in balance with myself, that’s when I took “the” deep dive in what is now my life path, living passion and a new career as a master scuba diver trainer in the amazing unmatchable underwater world of our beautiful blue planet.
Since then I just want to live my passion and to transmit my love for the oceans to everyone.
