Erica made the jump from a corporate life on land to a very different kind of office—one with reefs, wrecks, and plenty of ocean life. After years spent in the mountains of New Hampshire and Vermont, she traded snow for saltwater and hasn’t looked back since.As a PADI IDC Staff Instructor and Director of Dive Center Operations, Erica teaches, mentors, and helps keep everything running smoothly behind the scenes. She’s especially passionate about marine life and wreck diving, and still gets excited every time she drops onto a new site—especially if there’s a chance of seeing something big and unexpected. She’s also a strong believer that diving should be fun, approachable, and full of personality, whether you’re a first-time diver or working toward professional-level training.Currently working toward her Master Instructor certification, Erica has her sights set on becoming a PADI Course Director in the near future—and she brings a lot of energy (and snacks) along for the ride.Fun fact: Erica loves sharks, wrecks, and deep dives… but has an extremely specific fear of latex balloons. No questions asked.

Leslie’s path into diving started with a snorkeling trip in Hawaii that turned into a Try Scuba experience—and that was it. She was hooked. Not long after, she found herself back in the water, this time working toward becoming a dive professional.She’s now a Master Scuba Diver Trainer across PADI and SSI, teaching a wide range of specialties and helping divers build confidence, comfort, and awareness underwater. From buoyancy and navigation to marine ecology and rescue skills, Leslie enjoys meeting divers where they are and helping them grow at their own pace.The Florida Keys hold a special place in her story, as it’s where she did her first ocean dives. She loves that no two days underwater are ever the same, and she’s always excited to share that sense of discovery with guests.Outside of diving, Leslie plays drums—bringing the same rhythm and energy above the surface that she brings to the ocean.

Merlin has always been drawn to exploration and life at sea. For him, diving is exactly that—an opportunity to step outside the familiar and into a world that constantly surprises, from wrecks and reefs to encounters with marine life in their natural environment.As a PADI MSDT Instructor and licensed 100-ton captain, Merlin spends his time teaching, guiding dives, running boats, and keeping the behind-the-scenes systems of the shop running smoothly. He enjoys sharing the experience of diving with others, whether it’s their first descent or another step in a long diving journey.Having traveled widely in pursuit of diving, he considers Key Largo one of the most complete dive destinations anywhere. The variety is what keeps him here—shallow reefs, deep wrecks, and everything in between, all in one place and always full of life.Fun fact: Merlin has crossed Alaska by dog team—three different times!
