WHEN SOMETHING GOES WRONG, WHO ARE YOU GOING TO CALL?

The internet can sell you dive gear—and it does. But it can’t help you the a few days before your dive trip when your regulator is acting up, your computer isn’t cooperating, or something just isn’t working the way it should.

At Atlantic Edge Scuba, we’re here after the sale.

When you walk into Atlantic Edge, you’re not dealing with a warehouse or an anonymous call center. You’re dealing with Terry, Rusty, John, and the rest of the Atlantic Edge team—people who know diving, know the equipment, and know many of our customers personally.

We help troubleshoot problems, handle warranty claims, service and repair your equipment, and do everything we can to keep you diving.

We know our divers. We remember the equipment you use, the training you’ve completed, the trips you’ve taken with us, and often where you’re headed next. When you need help, you know exactly who to call—and you’ll talk to someone who actually knows you and knows diving.

For more than 33 years, Atlantic Edge has been about more than selling scuba gear. We train divers, service their equipment, travel the world with them, and help them continue their underwater adventures.

We’re not the big-box dive shop.

We’re Terry, Rusty, John, and your Atlantic Edge dive team. We stand behind what we sell, answer the phone, and we’re here when you need us.

Meet Harvey — Atlantic Edge’s Running & Diving Coach

If Harvey isn’t underwater, there’s a pretty good chance he’s running, swimming, kayaking, training for a triathlon, tinkering with his 1955 Chevy pickup—or brewing something in the garage.

Harvey’s diving story began in 1983 while attending Hampden-Sydney College. After graduating in 1986, his dive gear took an extended surface interval until his honeymoon in 1994. That trip got him back underwater, and he hasn’t stopped diving since!

Today, Harvey is an Atlantic Edge Scuba Divemaster who especially enjoys working with newer divers. One of his favorite parts of diving is watching students go from a little nervous to completely excited about being underwater.

“Seeing the excitement of new divers never gets old.”

From Oysters to Sea Lions

Harvey’s logbook has a little bit of everything. His favorite adventures include diving Nassau in the Bahamas, harvesting oysters in the Patuxent River and Chesapeake Bay, exploring the Horse Ferry wreck in Lake Champlain, swimming with turtles in Lahaina, hanging out with sea lions at La Jolla Cove, and diving the Vandenberg in Key West.

He also has a soft spot for aquarium diving. Two favorites are EPCOT and the National Aquarium, where he enjoys visiting what he affectionately calls “my fish.”

But for Harvey, the people are every bit as important as the dive site. He loves diving with friends and meeting new people on dive boats, but some of his best dives are with his son, daughter, and son-in-law.

Running Shoes Meet Dive Fins

Harvey doesn't exactly sit still when he's above water.

He has completed the Marine Corps Marathon three times and now runs distances from 5Ks through half marathons. He’s also a certified running coach and volunteers with the Montgomery County Road Runners Club. These days, he enjoys running half marathons with his son, who has the ambitious goal of completing one in all 50 states plus Washington, D.C.

And apparently running isn't enough cardio.

Harvey grew up as a competitive age-group swimmer and now participates in open-water swims from one to 3.1 miles, recently completing a 2.5-mile ocean swim in Cape May. Add sprint and Olympic-distance triathlons and kayaking, and the nickname “Atlantic Edge’s Running & Diving Coach” starts to make a lot of sense.

When he finally slows down, Harvey enjoys driving and showing his 1955 Chevrolet pickup and homebrewing b**r, kombucha, and other fermented creations.

What's Next?

There are still plenty of blank pages in Harvey's dive log. Iceland, North Carolina, the St. Lawrence Seaway, and the Pacific Northwest are all waiting on his bucket list.

At home, life includes two rescue dogs—a beagle and an American Staffordshire Terrier—a rescue cat, and, appropriately enough, fish. Harvey is also an Eagle Scout and has called the DMV home since 1973.

During the workweek, Harvey trades his regulator for spreadsheets as a Commercial Credit Underwriter at EagleBank, where he has worked for 10 years after previous positions with TD Bank, Chevy Chase Bank, and Sovran.

Whether he’s coaching someone through their first dive, crossing another finish line, swimming a few miles in open water, or heading out on a dive boat with family and friends, Harvey seems to follow one simple philosophy:

Keep moving, keep exploring—and never turn down a good dive!

Meet Kasim — Master Scuba Diver Trainer & Aquarium Enthusiast

If there’s one thing Kasim loves almost as much as diving, it’s helping other people discover just how much fun being underwater can be.

As a Master Scuba Diver Instructor, Kasim’s teaching philosophy is simple: relax, master the basics, and enjoy the dive! He takes the time to make sure his students are comfortable and confident with their fundamental skills. After all, scuba diving is supposed to feel like an adventure—not an underwater final exam.

One of Kasim’s favorite places to teach is the National Aquarium. There’s something pretty special about introducing divers to an incredible underwater world while fish, rays, turtles, and other Aquarium residents cruise by to supervise the lesson. Talk about a classroom with a view!

Kasim also believes that entering the underwater world is a privilege. He encourages every diver he teaches to respect the environment and do their part to leave the ocean better than they found it. Good buoyancy, good diving habits, and respect for marine life make for happier divers—and happier fish.

When Kasim gets the chance to travel, some of his favorite dives include Blue Heron Bridge in Florida, the EPCOT reef at Disney World, drift diving in Cozumel, the wrecks off Key Largo, and diving throughout Italy.

And when he's actually on dry land? Kasim is usually tinkering with his 3D printer, trying to perfect the perfect cup of coffee, or working in the garden. Apparently, sitting still just isn't one of his specialties.

So, the next time you see Kasim at Atlantic Edge—or better yet, at the National Aquarium—join him for a dive! Just be warned: you may leave a more confident diver, with a greater appreciation for the ocean…and possibly a very strong opinion about how coffee should be brewed.
