Background:

Ed first got certified back in 2000, but for a long time, diving was a rare vacation treat—just a couple of dives a year in tropical destinations. That all changed in 2018 when he decided to spend a summer at Utila Dive Centre in Honduras and earn his Divemaster certification. It planted a deeper seed, but it wasn’t until 2019—when COVID shut down international travel—that Ed truly reconnected with the sport.

That summer, he started diving regularly with the MetroWest Dive Club and never looked back. Through the local community, he rediscovered his passion for the underwater world—and picked up a new obsession: macro photography. With help from a few talented mentors, Ed found a whole new way to experience diving, one tiny, incredible subject at a time.

Favorite Dive Site:

Ed’s favorite local dive site is Fort Wetherill—and specifically, at night. The visibility? Often terrible. The water? Surprisingly warm. But the biodiversity? Absolutely unmatched for macro photography. It’s one of those spots where you truly never know what you’ll find—octopus, seahorses, squid, mantis shrimp, eels, and all kinds of tiny, wonderful weirdness hiding in plain sight. For Ed, it’s the kind of dive that makes you slow down, look closer, and fall in love with the details.

Favorite Creature:

When asked about his favorite underwater creature, Ed gave the most honest answer possible: dog. While they might not have gills (yet), dogs bring the same kind of joy, curiosity, and goofy charm that Ed loves spotting in the ocean. But if you press him for a real underwater pick? Probably anything tiny, weird, and photogenic enough to chase with a macro lens.

Favorite Certification Course:

For Ed, Rescue Diver was a game changer. It was the course that opened his eyes to the deeper responsibilities that come with diving—looking after not just yourself, but your dive team. It was humbling, challenging, and empowering all at once. More than any other class, it’s what inspired him to keep pushing toward professional-level training and to always approach diving with a mindset of awareness and care.

Goals In The Dive Industry:

Ed isn’t just a diver—he’s a science teacher serving the Dorchester community, and his goal is to share his passion for scuba with the next generation. He’s especially focused on creating access for BIPOC students, helping them see diving not just as a recreational activity, but as a real pathway into environmental science and marine biology. Whether it’s through mentorship, storytelling, or simply showing up in spaces where representation matters, Ed’s mission is clear: to open doors underwater and above.

Dive Kit:

Ed’s kit is a perfect reflection of his style—practical, personalized, and built for exploration.

He dives a Halcyon Eclipse backplate and wing with custom colors and a small backplate that fits him like it was made for him (because it kinda was). Paired with his Santi Elite+ drysuit, which strikes the perfect balance between flexibility and toughness, he’s geared up for any New England conditions that come his way.

For propulsion, he swears by his Hollis F1 fins with yellow tips—not just stylish, but seriously powerful and perfect for back finning when lining up those perfect macro shots.

And when it comes to cameras? Ed’s in love with his Olympus EM-1 Mark III in an Isotta housing. It’s compact, lightweight, and delivers professional-level image quality. With a 30mm macro lens for local underwater critters and a 90mm macro for insect photography topside, it’s the system that lets him chase tiny beauty wherever it hides.
