About me

Mexico surface interval

My name is Agnieszka (Aga) Kostera-Kosterzewska and I am originally from Poland. After working as a teacher for many years, in 2013 I moved to Gozo and I have never looked back. I had worked for diving centres in Gozo for twelve years before I became a freelance diving guide and instructor associated with Blue Hole Diving centre in Marsalforn (MTA reg. no DIVE/G/003). In addition to being a diver, I am also a translator for PADI and DAN.
