Matt Zimmerman

Matt moved to the island of Oahu in the year 2000 after completing a Ph.D in Biomedical Sciences at UCSD. Having already completed a PADI Instructor level certification, it soon became clear to Matt that one could support an avid diving habit on the island of Oahu by taking island visitors scuba diving – score!

What was at first an informal local diving club quickly became a part time business run from a one bedroom ground floor apartment in Waikiki. That part time business soon became a full time endeavor with a new friends/divemasters helping out (moved up to 2 bedroom apartment). Eventually, a strong local reputation led to a diving service contract on Joint Base Pearl Harbor Hickam and the evolution of Island Divers Hawaii into a traditional, established dive store.

Success serving the military led to the opening of a second retail location at the Hawaii Kai marina and shortly thereafter the addition of the vessel Sea Fox imported from Florida. Since then the scuba dive vessels Dive Barge, Sea Hound, and Enzo were added to the fleet. While a couple of those vessels are leased out to other interests, we still go diving on them from time to time. Matt believes that the success Island Divers has enjoys comes from his position that customers are friends.

Matt started Island Divers with the goal of making customers into friends, and that principle has guided the growth of the business. Matt tells a story to each new instructor that comes into the business.  “A diver may remember what they saw on the dive, but for sure they will remember how they were treated at the dive shop and how you made them feel about diving with Island Divers”.  The dive professionals selected to work at Island Divers are chosen because they are friendly, outgoing people that truly enjoy sharing their passion for diving with a new group of divers every day.  The people you will find on this page are the best of the best.

Most recently, Matt became the president of Hawaii Scuba University.  Coming full circle back to academic life and incorporating of a decade of experience in the diving industry, he is very excited about the training programs being offered and is looking forward to tackling the opportunities the school represents.

John Miller

John grew up in southwest Florida and was certified in 1986 earning his open and advanced open water ratings, along with several specialties. He spent most of his summers diving in the Florida Keys and throughout the Caribbean. After attending Marion Military Institute and subsequently earning his 1st bachelors in Psychology from Stetson University in Florida, John began his career as a military officer traveling the globe. While serving as a health care administrator, John continued his education earning a 2nd bachelors in Health Information Management and a Masters in Health Information Systems. John’s job moved his family to Hawaii in 2010 and he could not have been happier to be back on the water. He quickly went from an Advanced Open Water certification to recently receiving his IDC Staff Instructor Rating. His passion is infectious and his high level of instruction and attention to his students shows in the number of students that come back time and again to learn more.

Kendal Vercoe

Kendal was born and raised in Portland, Maine. Growing up in a traditionally nautical New England family, children are made into capable mariners as soon as they can throw a line. As such, Kendal was captaining his first boat on the “Downeast” coast of Maine by the age of 12. At 13, he began diving during one of the many family ventures out of the country during his youth. Spending much of his early years on and in the water, he developed a passion for the ocean and a profound respect for its power and its beauty, a passion matched only by his love for his beautiful wife Davy and his compulsion for traveling.

Naturally, Kendal began seeking a means to combine his interests with a career at 19, and moved to Sydney, Australia to learn how to teach SCUBA and became a PADI MSDT. Over the following decade, Kendal used his skills as a dive instructor and a mariner to not only become a 100 ton US Coast Guard Captain, an Australian Master Class 5 for shipping and trade, and a licensed Marine Engineer, but also to travel the world. He has lived and worked as Captain and/or Instructor in Indonesia, Thailand, the Bahamas, Kauai, Vietnam, Puerto Rico including the Mona Isles, the US Virgin Islands, the Dominican Republic, Australia and New Zealand.

Through his many miles at sea at the helm of a wide range of vessels, Kendal has had the good fortune to receive the experience one gets by spending years at sea, and the knowledge and skill it has afforded him are an asset he values greatly. At the same time, being responsible for the training and supervision of literally tens of thousands of divers from an expansively diverse cultural mix, Kendal has developed into an effective, observant and extremely adaptable Instructor.

Davy Eleen Vercoe

Davy was born in California but spent most of her life traveling the USA and a bit overseas with her beloved family. Her travels took her to Brazil where she lived and went to school for three years and met her future husband, Kendal. She fell in love with scuba diving the moment she took her first breath underwater at Blue Water Divers in Rochelle Park, New Jersey when she was 23 years old. She got her open water PADI certification two days after her graduation from college with a degree in Theater Arts. Davy went on to work for the very dive shop that certified her and thus began her climb to the exotic life traveling the world as a scuba instructor. She has had the pleasure of diving of the coast of New Jersey, the Caribbean Sea, Western Australia, and Bali, Indonesia.  Davy is passionate about sharing her love of the ocean and it’s inhabitants with future generations.

Davy’s favorite creatures to see underwater are any kind of rays, nudibranchs and octopus.

Lauren Smith

I am a Life Long Divemaster closing on 10 years in multiple facets of the business including Guiding, Dive support Supervisor  for documentary/TV productions, management, and Guest Liason for large groups in remote areas.

My “past life” was as a Marketing/Sales/Distributor Liaison for a Vodka company started by a hip hop artist back in the early 2K when the trend for Hip Hop Artists becoming Moguls in many facets of Merchandising began.

It was a whirl wind of fun and excitement but I knew, after spending my undergrad years overseas in Surfers Paradise, Australia before becoming “corporate”, that I wanted a life on or in the water.

I retired early from the fast paced life and moved to Costa Rica where I surfed, sun bathed, and sold real estate. I soon became best mates with a Dive Center owner and became a professional Diver.  Costa Rica is where I met my Scuba Instructor husband and started my travels that ended us in Africa, married and with a our son.

We moved closer to the states working in the dive industry of Mexico for a couple of years and now Hawaii.  I am the Customer Service and Marketing Manager For Island Divers Hawaii. I get to combine what I am good at, marketing, and my passion, diving!

Jeff Santos

Jeff was born in Fall River, Massachusetts but grew up in East Stroudsburg, PA where he learned to dive in murky quarries and flooded slate mines. Jeff went to college at Plymouth State University where he was a three time NCAA All-American Wrestler, graduating in 1997 with a dual major in Finance and American Economic Development.

Since then Jeff has lived in 20 cities in 11 countries in the past 16 years. In 2002 he moved to St. Petersburg, Florida and signed up for the PADI OW Course. Unfortunately, there were four Hurricanes that hit Florida in four weeks and the shop that he had chosen was forced to close after their boat sank.

So Jeff went looking for another place to complete the scuba course and found Mermaids Dive School in Pattaya, Thailand. He called that day and after talking to the owner, he quit his job and bought a ticket to Thailand. A week later Jeff landed in Thailand and started his Scuba Diving career. Eight months later Jeff was a open water scuba instructor.

Jeff then traveled all over Southeast Asia for three years, visiting Cambodia, Laos, Myanmar, Malaysia, before working as a dive instructor in Koh Samui, Thailand for two years. In March of 2006, Jeff flew to Oahu to work with Island Divers Hawaii and has been here ever since. Jeff likes to work the summer and winter months and travel a couple months in between seasons with his girlfriend, Charlynn, the owner of Gone Diving in Bellingham, WA and also an PADI MSDT. It is a rough life, but somehow he seems to manage.

Mark Savel

Mark grew up in San Diego, CA and has always spent time in and around the water. He first came to Hawaii in 1997 to study marine biology and oceanography at Hawaii Pacific University. He first took up scuba diving in the summer before his senior year of college in 2000 and found time at least once a week to avoid school work and go shore diving around the island of Oahu.

Upon graduating in 2001 Mark moved back to San Diego and started working in a dive shop. Over the next four years he worked his way up from an open water diver to an open water scuba instructor. But after getting tired of putting on a hood, gloves, 7mm suit, and a ton of weight to go shore diving, he decided to pick up and move back to Hawaii.

Mark has since been working at Island Divers Hawaii from 2005 and has become a Master Scuba Diver Trainer. His main passion in diving is photography and enjoys playing with his camera whenever he has a chance. Over the years he has been diving in Thailand, Grenada, Australia, California, and Hawaii.

Larry Hogan

Larry grew up with a great family, spending his youth exploring the tiger-filled jungles of rural Connecticut, and the ocean known as Long Island Sound. Not quite a valedictorian, he still really enjoyed NWCH high school in Hartford, and graduated from Villanova University, with lots of great friends and a degree in Psychology.

Which prepared him perfectly for a career owning and managing a construction company for over 30 years in New York city. While visiting Hawaii in the mid 70s with some friends, one of whom was a PADI CD, he was thrown into the ocean with a full set of dive gear on (thanks Dave) and immediately fell victim to scuba’s greatest danger – a serious addiction to diving.

Added to a love of travel, he has managed to dive all over the place and has seen and marveled at the profound sights the ocean offers, the great white sharks of South Africa, the giant mantas of Komodo, the whale sharks of Thailand, the white dolphins and piranhas of the Amazonian rain forest, as well as the Humpback whales, spinner dolphins, monk seals, and octopi of Hawaii.

He began the road to diving professional in the early 90′s assisting instructors at Beach 9, Brooklyn, Friday nights at the Y, and under the Throgs Neck Bridge in Queens (while still having a real job). A Master Scuba Diver Trainer since 2005 he has also worked in Phuket, Thailand, as well as NYC and now works with a great group of people at Island Divers Hawaii.

David Pinilla

Coming from Bogota Colombia, I have loved the Ocean since the first time I saw it when I was five. Since then, I always wanted to be close to it, if not in it. I did my first dive at the age of 12 in San Andres, Colombia and fell in love with SCUBA. I became a certified diver in Australia in 2000 and ever since I have been traveling the world SCUBA diving, looking for adventures, and exploring the beauty of the underwater world!
In Costa Rica, I became a PADI Divemaster in 2004, than a year later an OWSI Instructor, to fulfill my dream of being a Cruise Director for one of the best Live aboard vessels, the Undersea Hunter, in Cocos Island Costa RIca. After three years I decided to continue my dive adventures on the other side of the world, Africa. With my beautiful wife, I spent four years managing a resort Dive Centre in Zanzibar Tanzania. After having our son, we decided to move closer to the Americas, and landed in Mexico for 2 years where I became the Operational manager for a dive company in Mahahual Mexico.
I am now an IDC Staff Instructor with 10 Specialties under my belt and approximately 5000 dives.
I love the ocean even more than when I was five. It has given me some of the best experiences I have ever had, and I have seen things that I thought I would never see. Through experience I understand the importance of protecting the Ocean and taking care of it.

Kellen Bernhardt

I moved here from Seattle a little over two years ago. I started out cold water diving almost a decade ago and gravitated out of scientific diving into teaching diving.  I’ve always wanted to see a manta ray.  I will soon be a captain for the company and I hope to one day either work for NOAA or in medicine treating diving accidents or something like that.  I’m into surfing, biking, sailing, free diving to name a few.  I also like building doomsday machines.
