ERIK

ERIK

CAPTAIN/INSTRUCTOR

Erik is the owner operator of Extended Horizons, which he started in 1983 with two sets of dive gear and a lot of youthful energy! He is a US Coast Guard 100 ton Captain, PADI Instructor, SDI Instructor, regulator repair tech, Visual Cylinder Inspector, Certified Interpretive Guide, as well as our trailer repair tech, sometimes head mechanic and all-around maintenance and fix-it guy! If you’re lucky enough to dive with Erik, hold on to your hat! He is probably the most passionate, animated dive guide on our staff!

VICTORIA

VICTORIA

CAPTAIN/INSTRUCTOR

Victoria began her diving in 1986 in Nashville, TN, and has been with Extended Horizons since 1998, when she came out on a Lana‘i charter as an Open Water Diver and decided not to go home! She is Director of Operations, our lead Captain with a US Coast Guard 100 ton license, PADI Instructor, SDI Instructor, a Certified Interpretive Guide, as well as a Published Professional Underwater Photographer. Victoria is also a certified professional for Equine Assisted Psychotherapy (in her former life she was a horse trainer, but now she trains people instead!). Victoria developed the training program for our guides and captains; she does a lot of the organization projects around the shop, usually is our Costco runner, and she’s handy with a toolbox for our various projects around the shop! Of all of those skills, her passion as a dive guide is probably her greatest strength!

HOLLIS

HOLLIS

CAPTAIN/INSTRUCTOR

Hollis is originally from upstate New York, and had a passion for the ocean from a young age.  She decided she wanted to be a marine biologist by the time she was 8 years old, and when the time came she pursued that degree at the College of Charleston.  Her first ever dive was on the Great Barrier Reef in 2011 and she was back 7 years later working as a diver!  Since then she’s made her way here to Hawaii, first diving on Oahu, and for the past 5 years here on Maui.  She loves blowing bubbles, making fish friends and sharing stories about Maui’s marine world with our guests!

SHELBY

SHELBY

INSTRUCTOR

Howdy Ya’ll! Shelby is from Texas and began her dive career as Junior Open Water Diver in 2009. Driven by her curiosity into the underwater world, Shelby earned a Degree in Environmental Science, and soon after graduation moved to Honduras to pursue her Instructor Certification and begin her professional Scuba Diving career. She has participated in Coral Restoration Projects and Eco Programs, and began teaching at Extended Horizons in June, where she loves sharing and obtaining knowledge of the Worlds Oceans.

EMMA

EMMA

INSTRUCTOR

Emma is originally from Los Angeles but has always thought of Maui as her second home. Her mom was born on island and Emma visited her family frequently growing up. She always loved wildlife and decided to pursue a degree in Animal Science and Biology. During her studies, she worked with marine mammals and interned at the Maui Ocean Center where she learned about Hawaiian sea creatures. She earned her Divemaster in Australia and her Instructor certification on Maui. Emma is an enthusiastic, yet calm diver that loves to talk about anything conservation or animal behavior related. Surprising fact: Emma’s first dive was right here on Maui at Kahekili Beach as a teenager.

BRUCE

BRUCE

INSTRUCTOR

Growing up in the Philadelphia area, Bruce was fascinated by ocean creatures, particularly sharks and whales.  He got his open water diving certification in 2015 in Monterey CA and has since been lucky enough to dive some great locations in the world including Indonesia, French Polynesia, and the Caribbean. After many years of working in the tech industry in San Francisco, Bruce was ready to do his PADI instructor training in the Florida Keys in the summer of 2021, and then move to Maui to pursue his dream of teaching scuba and getting to dive Maui’s great dive sites every day.  Bruce likes to geek out watching any nature documentaries like Planet Earth or Secrets of the Whales that come out!

RACHEL

RACHEL

INSTRUCTOR

Rachel grew up in Pennsylvania where the two mouths of the Susquehanna Rivers meet. She has loved being in and on the water since she was born, fascinated by the underwater world. In college, she was torn between her love of the ocean and its creatures, and her love of human interaction. She ended up with a major in Anthropology and a Biology minor. Rachel was lucky enough to have her first dive experience on the Great Barrier Reef in Australia and has taken every opportunity to dive since. In 2019 she decided to make things official, and became certified in Greece, going from Open Water to Assistant Instructor in six months! Rachel completed her PADI Instructor Course on the island of Maui and enjoys working with all of the people drawn here.

PHILIP

PHILIP

INSTRUCTOR

As a child Philip was fascinated with scuba, and he took his first opportunity to dive in New South Wales, Australia, which ignited his passion and love for the world’s oceans. Then and there he decided he would become a scuba instructor, and upon returning to Idaho, Philip completed his PADI Divemaster training. Philip is a Boise State University graduate and he loves to share local culture and history. He lives by the motto “if you pick up treasure, you must also pick up trash.” He loves volunteering his time with Project Aware Dive Against Debris. His dive experience ranges from Australia, cold dark lakes of Boise Idaho, Key West Florida, Cozumel, Pacific NW glacial altitude dives, and now beautiful Hawaii. Philip joined Extended Horizons in 2021 so that he can share his love of conservation and diving with everyone he meets from around the world!

BRAD

BRAD

INSTRUCTOR

Brad was born and raised in the Pacific Northwest. He was the person who said he would “never go scuba diving,” until a friend somehow convinced him to take a tiny leap of faith and give it a try. Life changed. Brad’s passion for diving this beautiful blue planet with others led him to become a PADI Master Scuba Diver Trainer in 2021. The beauty and tranquility of the underwater world captures him on each dive and he looks forward to sharing this with you!

GABI

GABI

DIVE MASTER

Born on a small island in Brasil to a swim instructor mom and a surfer dad, Gabi has always felt a special connection to the water. After moving to Arizona at a young age, the ocean felt more like a dream than reality but the pool is where she felt most comfortable. While in college she discovered SCUBA diving in the lakes of Arizona, and soon after, she had the opportunity to dive in the Turks and Caicos Islands while doing marine biology research with a study abroad program. While in TCI she fell even more in love with the ocean and SCUBA diving but going back to the lake didn’t feel right, so she took a break from diving while she finished up her B.S. in Conservation Biology. As soon as she earned her degree, she went back to Brasil to visit family and ended up staying there to get her divemaster certification. Gabi enjoys learning about the “underwater world” and views every dive is an opportunity to see something new. She is excited to share her knowledge with you.

MAREN

MAREN

INSTRUCTOR

Maren began her dive career in 1999 at UC Santa Cruz, where she went from Open Water Diver through to DiveMaster, while earning a Bachelors degree in Psychology. She decided Maui would be the ideal place to follow her dreams and became a PADI Instructor in 2004. She started with Extended Horizons in 2005, and hasn’t looked back… in fact that’s kind of her thing, always looking forward. She’s now dive guiding with us as a fill-in only, because she has started a new career as a Paramedic and a mom! Maren’s can-do attitude and focus on quality customer service makes each charter with her special

WHAT WE HAVE TO SAY FOR OURSELVES

We’ve been scuba diving in Maui and operating boat charters to Lanai since 1983. We offer the highest quality Maui scuba diving and Maui shore dives that can be found departing from the island’s west side. If you don’t already have your scuba certification, our Maui dive shop can help with that. Our commitment is to creating an experience for divers of all skill levels that is safe, fun, interesting and first class. No matter if you’re diving with us on Lanai or Maui, our scuba dive guides are trained in the local ocean ecology and have years of experience as Instructors.

Take the opportunity to dive Maui by joining our guides on their scuba diving tours that highlight marine behaviors. Any guide can point out the obvious like turtles, but our Maui scuba diving guides actually know the names of fish and can interpret marine life behavior patterns. Their years of experience scuba diving Maui and Lanai allow them to know where animals live, when they mate, and why they are acting unusual.

Extended Horizons leads by example, and has started a movement here on Maui by being one of the first dive shops in Maui to talk about saving the reef and actually take action. To prevent anchor damage, Extended Horizons spearheaded the actual putting in of the first 14 moorings on Lanai in the late 90’s and continues to sponsor local NGO’s, working hard to make Maui County, including Maui, Molokini and Lanai, a mooring friendly place. Additionally, Extended Horizons conducts semi-annual underwater reef clean-ups. So far we’ve removed over 1000 of pounds of marine debris off Maui County’s reefs over the years through impromptu as well as organized Reef Clean-Up events! Extended Horizons conducts semi-annual underwater reef clean-ups. Check it out on our SPECIAL EVENTS page!  And we are proud to have inspired many other local shops to follow suit.

We have the ONLY commercial marine tour boat on West Maui running on 100% biodiesel (not the only dive boat- the only commercial boat). Our commitment to run 100% is unique. While some Maui dive shops and businesses try to greenwash their image stating they run biodiesel, often this is just a small percentage blend. (Sometimes as little as 1%). Better yet, our biofuel is made locally in the State of Hawaii from recycled feedstocks by Pacific Biodiesel. It does cost slightly more than regular petrol diesel however it is much much much easier on the environment, reducing our carbon footprint (finprint?) by over 80% compared to petrol diesel.

With over 40 years in the scuba industry, we rely heavily on repeat business & word of mouth.

Everyone says “we’re the best” in Maui shore dives and Maui scuba diving trips. However, if you’re interested in Maui diving but prefer an unbiased opinion, check out what others say about our Maui diving by looking at reviewer sites like Yelp or TripAdvisor.

If you would like to dive in Maui or Lanai, please call us for scuba diving reservations! We will show you Maui and Lanai scuba diving with a quality difference such as using large tanks (80’s) for all divers, making computers a standard part of our rental gear, and showing you the unusual and rare sites that Maui and Lanai have to offer.

You can read about moorings on Maui and Lanai and help with the effort. Make a donation earmarked for Lanai moorings or Maui moorings by a click to MALAMA KAI. Donation is tax deductible and will make a difference on Maui’s and Lanai’s reefs for scuba divers and snorkelers today… and in the future.
