Stelios discovered diving at an early age. He was only 13 years old when he started to free dive. He was introduced to the world of SCUBA by the age of 19 when he joined the underwater demolition team of the Greek NAVY (U.D.T.-NAVY Seals). Becoming PADI Open Water Instructor and Free Diving Instructor was the next step in order to pass down his acquired knowledge to his students. Stelios is a PADI Tec Rec and full Trimix Instructor and although he enjoys all types of diving, he thrives the most doing technical deep dives.
