As someone with cerebral palsy and a certified open water diver, accessibility and safety are incredibly important to me. Today I went out with Sea Dwellers Dive Center for some adaptive diving, and I truly can’t say enough positive things about my experience. Erica, Beau, Jasmine, and Captain Kate were all absolutely outstanding. Getting on and off the boat was smooth, safe, and stress-free, which made a huge difference for me. They were incredibly attentive, offered help with my gear, and made sure all of my needs were met without hesitation. Their professionalism, kindness, and genuine care made the entire experience enjoyable and comfortable from start to finish. Needless to say, I had an amazing day of diving thanks to the entire crew. I highly recommend Sea Dwellers to anyone looking for a safe, welcoming, and exceptional dive experience!

Everyone at Sea Dwellers was so nice. From the moment we booked our trip over the phone to the moment I had to return to grab my rattler that I left on their BCD I rented, all the staff we encountered were friendly, knowledgeable, and kind. Special shout out to Sebastian in the shop who was awesome, Emily who was our scuba guide and was thorough with our dive plan and knowledgeable about all the micro critters, Jasmin who made sure to point out all the cool animals she spotted and who was so excited for us to find some sea turtles, Tony who worked hard as our deck hand, and Captain Dave who kept us safe and provided cold water and sunscreen on his cool boat :) highly recommend this dive shop. Can’t wait to come back! (Also, 2 shop dogs that alone are worth the visit bc they are adorable and like pets)

Absolutely — here’s a polished review that still sounds warm and personal: Sea Dwellers made it possible for me to go from an uncomfortable snorkeler to a PADI-certified Open Water scuba diver in just two days. I honestly never thought that would be possible. The entire team was supportive, professional, and encouraging, but I especially want to recognize Leslie. Her patience, calm presence, and genuine care made all the difference. She is an incredibly gifted teacher who knows how to build confidence while making you feel safe and supported every step of the way. I’m so grateful for the experience and would highly recommend Sea Dwellers, especially Leslie, to anyone learning to dive.

Always love going out with Sea Dwellers. They’re the only company I go out with in Key Largo. Captain Kate and Merlin were amazing and they have everything you could need on the boat. I’m always looking forward to my next diving trip with this company!!

We went diving with Sea Dwellers on June 15th , we have been diving with them for many years and once again the staff was great, the boat not over booked and the dives were fantastic. There is a lot of competition in the area for diving and we will always go with Sea Dwellers. See you in August... August has come and gone and we have another great dive with Sea Dwellers under our belt. We dove the Spiegel and the Benwood wrecks. As described above, everything was fantastic! The composite photo includes all photos taken on the last two Sea Dweller trips. Another Great dive with Sea Dwellers, yesterday, May 6, 2026. We encountered a HUGE Goliath Grouper on the Benwood Wreck. We generally dive with Sea Dwellers every two months or so. Always a great experience. We highly recommend them for their great care and service. Photos of the big guy attached.
