Luis Arpa

Director and Staff Instructor

Born and raised in the northern spanish mediterranean coast (26/11/1980) Luis has been in Thailand since 2013. He discovered the underwater world in 2001 when he got his first diving license and has been diving around the world ever since. Today he’s ranked as PADI MSDT and SSI OWSI. He is fluent in english, spanish and catalan. Luis always had a deep admiration for the ocean and its inhabitants. After getting a degree in Biology he decided to move forward in the field and get a Ph.D. in immunology which, eventually, allowed him to move to Southern California and get a possition as a postdoctoral fellow in a worldwide reknowned research institute. But he soon realized living within 4 walls surrounded by microscopic beings wasn’t his thing and, two years later, he decided to quit science. By that time he already was an experienced Rescue diver. It wasn’t though until he met his friend and bussiness partner Guillermo a few months later while they were taking classes to become comercial boat captains that together they decided to move to Thailand and take over a small dive center in Koh Samui, which was on sale by that time. Furthermore Luis is a diehard fan of the great masters of history.
