Her love of the outdoors had her working as a hiking guide in various locations around Europe but when she tried scuba diving… that was it!!  She found her true love in the underwater and has since qualified and worked as a scuba instructor.  Her calm personality comes across immediately which makes her perfect for nervous first time divers and children.  Iliana always states that the best reward for an instructor is the smile of first time divers which she will never tire of!!  Iliana is also keen on marine conservation and is a volunteer in several marine projects.  When she’s not in the water (which is rarely) she loves to travel, hike, read, cook and generally be outdoors.
