Nikoletta Efstathiou

Dive Master  – Nikoletta is always smiling and putting everyone in a good mood – she spends more time in the water than on dry land!!





Nationality:   Greek / Canadian

Born:     1993

Speaks:     English, Greek


Nikoletta was born in Athens and has a Architecture degree from the University of Toronto in Canada with a minor in Environmental Studies.  Her love for scuba diving has led her to certify as a dive master and to work in diving before she continues her studies in the field of architecture…. unless scuba diving captures her heart even more and then who knows where she’ll end up! Nikoletta has been spending summers on Alonissos since she was a little girl and her knowledge and love of the island comes through immediately!  In addition to diving, Nikoletta loves camping, reading, traveling, designing and learning about environmental conservation.


These are the brave souls who have decided to change their lives, join us on our beautiful island in Greece and learn to become Diving Professionals.  If they look tired they are…… If they look like they have been shouted at…they probably were, and if they look scared…. then they haven’t been studying for their exams!!!!!
