Meet Your Key Largo Scuba Diving Experts

Professional Guides with Decades of Key Largo Expertise

With over 50 years of collective experience navigating the Florida Keys National Marine Sanctuary, our team represents the gold standard of professional scuba diving in Key Largo. Led by owner Pete Moum, alongside dedicated experts like Beau and Erica Walker, each member of our crew is deeply rooted in the local maritime community. We bring deep industry expertise to make every trip educational and well-managed. Our staff consists of highly trained PADI instructors and divemasters holding premier certifications, all sharing a singular commitment to the highest safety standards in the industry.

What truly makes our team unique is the perfect balance of technical precision and approachable personality. We don't just guide trips; we share our home with you, offering insider insights into reef health, fish behavior, and the hidden history of our local shipwrecks. Instructors like Beau are passionate about helping divers build confidence, creating a safe, relaxed, and enjoyable learning environment for everyone from first-time students to technical veterans. Whether you are working through a new PADI certification or exploring deep ledges, our experts provide the calm, steady guidance that only comes from decades of life on the water.

Since 1972, Sea Dwellers Dive Center has served as the gateway to the "Diving Capital of the World." As a premier PADI 5-Star Dive Center, our service specialty is providing a boutique, customer-focused approach that prioritizes education, safety, and more time underwater. We are famous for our 65-minute "pool open" times, giving you the freedom to explore the reef at your own pace without feeling rushed. Our spacious dive vessels, the Sea Dweller and the Ocean Dweller, ensure a stable, comfortable ride away from the large "cattle boat" crowds. Experience the coral reef with a staff that treats you like a local—whether you are seeking 2-tank reef dives, advanced wreck diving on the Spiegel Grove, or peaceful snorkeling tours, our family is here to guide yours.

Pete Moum

Key Largo, FL

President, CEO, Owner, Master Boat Captain and Scuba Instructor

Pete is the guy who keeps Sea Dwellers running. Whether he's at the helm of the boat, helping with scuba classes, or making sure guests have a great experience, he's usually involved in just about everything.

A lifelong passionate diver, Pete loves introducing people to the incredible reefs, wrecks, and marine life of the Florida Keys. If you've spent any time around the shop, you've probably heard one of his stories-- or one of his jokes.

Fun fact: Pete has a fear of marshmallows. Sharks, deep water, and rough seas don't bother him. Marshmallows, on the other hand, are a different story.

Beau Walker

Key Largo, FL

Director of Instructor Development

Beau's passion for diving started with a simple goal: helping others discover the incredible world beneath the surface. Today, as Sea Dwellers' Director of Instructor Development, he trains and mentors divers at every level, from beginners taking their first breaths underwater to future dive professionals pursuing their own careers in the industry.

With an extensive list of instructor ratings and specialties, Beau is especially passionate about education, conservation, and developing confident, capable divers. One of his favorite things about diving in the Florida Keys is the abundance of shipwrecks, each with its own story and unique marine life to explore.

When he's not in the water or teaching, Beau is working toward his goal of becoming a PADI Course Director—the highest level of recreational diver training.

He also shares his adventures with his German Shepherd, Bjørn, who may not dive, but is always ready for the next adventure.

Jasmin Johnson

Key largo

Instructor, Guide, Deckhand, Shop Staff & Social Media

Jasmin does a little bit of everything at Sea Dwellers. Whether she's teaching scuba classes, guiding dives, helping on deck, assisting customers in the shop, or creating content for social media, she's always finding ways to share her love for the underwater world.

Although she grew up far from the ocean, Jasmin was drawn to the water from an early age. After trying scuba diving in college, she was hooked from her very first breath underwater. That experience inspired her to become a dive professional and help others discover the same sense of adventure and wonder.

Before moving to Key Largo, Jasmin built her diving career in cold-water environments surrounded by kelp forests. Today, she enjoys exploring the Florida Keys' vibrant coral reefs and introducing divers to everything this unique underwater ecosystem has to offer. She is passionate about education, safety, and helping divers continue their journey, whether they're earning their first certification or working toward professional-level training.

When she's not diving, Jasmin loves creating art—especially pieces inspired by nature and the ocean life she encounters beneath the surface.

Erica Walker

Key Largo, FL

Director of Dive Center Operations

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 Lawson

Key Largo, FL

Instructor, Deckhand & Guide

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.

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.
