Dias greatest love since his early childhood has been the vast blue sea. A major role for this is the fact that he comes from a family that has dedicated their lives to the commercial and military navy. He has been sailing since the age of 9, diving since the age of 13 and since as long as anyone can remember he’s had a mask and a snorkel attached to him! He started his studies at the Technical University of Crete in the department of Electrical and Computer Engineering but he never finished due to the fact that his heart belonged with the sea. With over 6000 dives in Greece and around the world – Dias has worked as a sailing/motor boat Skipper, Divemaster, Instructor and manager in respectable dive centers throughout Greece. A great instructor with an emphasis on safety – Dias will make your diving experience unforgettable!
