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.
