About Us


Our History

George, Tanja and Dimitris are the co-founders of the Sea World Diving Center Kos. We are divers with different backgrounds and experiences who share a common passion for diving and for the environment. We met in the beautiful island of Lesvos and after having worked together for several seasons, we decided that the time has come for the diving virus to be spread further. During our quest for a new destination, we gladly accepted to become members of the Sea World Diving Centers’ family. Sea World Diving Center Kos is operating within Ikos Aria Resort premises and is ready to offer a variety of activities to all divers of any level. Our goal is to share our passion about the underwater world and diving and make all divers and non-divers aware of all the environmental challenges that this magical world is facing.

Co-founder and OWS Instructor

Dimitris had his first contact with scuba diving at the age of 6 thanks to his father, who infected him with the “scuba virus”.

Though he obtained a degree in industrial management, his love for the sea made him pursue a career in the maritime industry. From 2009 to 2016 Dimitris worked as commercial diver and ROV operator in various underwater projects.  Driven by his insatiable appetite for expanding his understanding on the marine environment Dimitris continued his studies. He is a Master graduate in intergrated coastal management and in sustainable Blue Growth. His goal is to promote marine protection and conservation through scuba diving.

Environmental awareness for Dimitris is a key factor in creating a brighter future by reversing the man-made issues. Promoting environmental awareness through diving was always Dimitris’ dream, which he managed to realize after his cooperation with George in Lesvos scuba diving center . Starting as affiliates, Dimitris and George united their competences by founding another diving center in Kos “Sea World Diving Center Kos” together,  hoping to bring as many people as possible to experience the joy of diving!

OWS Instructor

Ever since Ian was a little kid, he loved being in the water, whether that would be the bath, pool, or the Ocean. This all escalated when he was forced into his first diving course when he was 12 by his father, originally he wasn’t interested at all, but right after his first open water dive, his world was flipped on its head, and he knew that if he could then this would be his future.

When he was finishing high school, he saw all his classmates choosing Universities to attend, and he was not interested in that at all, he wanted something more, something exciting, and so decided to leave that all behind and go for his instructors course at 19.

He never thought he would be able to turn his hobby into a job, but yet he did, and has not looked back since that day.
