We have a fair bit of diving experience, and Mark is among the best dive masters we’ve experienced. We had two full days of diving with him. For the important... read more stuff he was excellent— knowledgeable, clearly puts safety as a priority, attentive, and thorough. We never felt anything but complete comfortable with the safety and diving aspect of the trip. On top of that, Mark was a fantastic guide and a good dude. Honest, accommodating, and we felt like we got a true local perspective and experience rather than just being run through your typical group dive machine. We would go right back to him for our next trip without question.

  Thank you Mark Brown!! For a great dive at my birthday, with cake, decorations, music and of course the very pleasant guidance above and under water!

  Mark did an excellent job fulfilling all of my crazy requests. We communicated over many emails before the trip and he was always accommodating. Mark is honesty, straight forward, and... read more communicates well. We did night diving, day diving, snorkeling, sightseeing, local foods. He made sure that everything was as perfect as it could be. Mark is an excellent diver/instructor/guide. He helped hone skills while keeping it relaxed and fun. He made sure we were safe and comfortable. He took photos of us while we were diving and sent them the next day (not professional photos, just what he could take with his underwater camera). He was always on time, courteous, and always with a smile. I'm sure that there are many great dive shops on the island, but if you want truly personal service I highly recommend Mark at Twindivers.
