Marisa has logged more than 1000 dives all over the world, in the Caribbean, Indonesia, Red Sea, Maldives, etc. Marisa is also a  surfer and is a  certified ashtanga vinyasa yoga teacher.  When she’s not in the water or teaching she loves to hike with her dogs or train for her first marathon.

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!!!!!

Nationality:    Australian and Greek

Born:     1995

Speaks:  English, Greek

  • Open Water Diver

Victoria has grown up loving the sea. Her most favourite feeling is when she is beneath the water and enters the place she associates with both peace and solitude.  Discovering and exploring life at the depths of the ocean is her true passion because when she’s under – good luck getting her out!  Victoria was born in Melbourne, Australia.  From a very young age Victoria and her family traveled… and travel always included the sea.  Many a trip was spent in the turquoise waters of the Greek islands where the summers appeared to be endless and the marine life awe inspiring.  In Thailand she experienced the beauty of free diving and snorkel and in New Zealand her love of water sports was realized. Victoria has always loved to travel and continues to add countries to her ever growing list. Upon completion of her Work Youth degree in 2018, Victoria made the decision to leave Australia and relocate to Greece. Prior to doing so, she had secured a position as an Adventure specialist and lifeguard at a summer camp in New York and spent the summer facilitating sessions in boating, high ropes, zip-wire and outdoor cooking. She also jumped at the opportunity to sky dive which has only added to her experiences with extreme sports.  Victoria has decided to sit still long enough to join our great team for the summer!  When she’s not in the water she loves to read, listen to music, hike and spend time with family and friends.
