Went on a two tank dive with Tom this morning and it was an incredible time. Diving with Tom is a one of a kind experience - because he's a marine biologist he has the ability to teach you about several fish and corals on the excursion. He also has endless stories to tell about past experiences. We were lucky... More

I just returned from a wonderful Dive vacation to Grand Cayman, a highlight of which was a week's worth of diving with Tom Byrnes and Cayman Marine Lab. This is always most enjoyable, and features great diving, with a tremendous variety. We dove on North side, West, and South. A strong weather front moved in, with Northeast winds blowing steadily...

Tom was great. He ended up certifying me during the trip. We did 6 total dives during our trip and it was a great experience. Tom not only was professional, he was funny too. I will be calling him every time we come back.

There is nothing better than diving with a marine biologist! Tom's knowledge base made our diving experience richer. Not only beauty, but education...you can't ask for more than that. We had a fabulous time diving with Tom and would definitely go back to dive with him again. KH

I just returned from a terrific week in Grand Cayman. I dove with Cayman Marine Labs on the North Wall and the experience was outstanding. Tom took us to multiple unnamed sites and the corals were amazing. Tom does a great job to get you to the best sites.

I have been diving with Tom for 15 plus years. Each time I've dove with him tops the past dive experience. He's a marine biologist so not only am I enjoying the dive, i'm learning as well... I highly recommend this experience for any level of diver!!! Tom, thank you for all you do and continue to do!
