Daniel grew up in and around the water. He’s been diving for 21 years. Daniel began diving with his mother, and he quite literally did a giant stride into it. He used to be a Search and Rescue Swimmer and a Navy Corpsman. After getting out he furthered his diving career by pursuing his goal of becoming a Divemaster in 2020. Daniel considers himself a lifetime student because he plans to continue to learn all that he can and grow as a recreational and professional diver. His favorite place to dive is Devils Grotto in Grand Cayman. Daniel loves all the swim-throughs of the giant coral heads. He has been teaching in a different industry for over 15 years now and loves teaching. He loves seeing a student get that “light bulb effect” when they get something they’ve been struggling with. That is the greatest feeling in the world for a teacher, and Daniel looks forward to bringing that passion and teaching experience that he have been blessed with for the last 21 years to new and old divers alike.
