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.
