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.

  I would recommend Mark Brown to any diver!

I booked a simple last minute two tank reef dive as I had no transportation. Mark responded very quickly and was... read more even willing to show up earlier than his normal opening hours since I would be dropped off quite early. When Mark heard that I had already done a discovery dive on his reef he decided to use his truck take me to two other amazing locations I didn't even know about as a local.

He really provided amazing service, tips on how to better myself as a diver and even went home to get his gopro to be my personal underwater photographer! Mark is really charismatic, the whole experience feels like you're having the time of your life with an old childhood friend instead of a simple guided dive. Up until now this has been my best guided dive by far! I will definitely follow some specialty courses here in the future.

  My son and I dove with Mark at Twindiver. Mark's love for people made this the best dive experience I have ever had. He bought us lunch between... read more dives and took us to exclusive spots where the sea life was amazing. These reviews are spot on. Mark is a great man.
