Pavlos Besis

From competitive swimming to the deep blue — Pavlos has always lived in the water. Between 1980 and 1996, he set six national records and was European Champion in Fin Swimming before discovering diving in 1997. Since then, thousands of dives have shaped his passion and experience beneath the surface.
With a strong background in technical and cave diving, Pavlos teaches with precision, discipline, and safety at the core of every course. A dedicated advocate of the DIR philosophy, he guides divers to explore the caves of the Aegean with confidence and control. For Pavlos, diving isn’t just a profession — it’s a way of life.
