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.

  Mark Brown (he operates the dive shop) is incredibly charismatic is able to teach even the most squeamish person how to dive. When you see him at work, you know... read more instinctively that you can just lean back and let him take lead. He is equal parts comedian and professional.

  Very social and fun diving instructor which made for a very relaxed dive for a beginner. Highly recommended and even gave advice dor other things to do on the island!
