After shopping around for dive centers on couple islands in Thailand, I chose Dive Careers in Koh Tao and from the first day I started the Divemaster course I knew I had made the right decision. Even disregarding the great location, facilities and dive sites, I would have still loved the course because of the instructors. Andrea was outstanding in her guidance and lessons. She exceeded my expectations and was truly our land and sea mentor. All other instructors led from the front and modeled leadership behavior for us Divemaster Candidates.
I wanted to fail the course so I'd have to take it all over again. But instead, the entire staff inspired me to continue with Dive Careers and take the Instructor course with them as well.
I wish I could add another star to their rating. :)
Keep up the good work!
