Craig Willemsen
        Instructor Trainer,
        Tech Instructor &
        Store Owner

Craig started diving in 1972 and for over 48 years has shown us that scuba diving is his passion. He has dove all around the world and keeps looking for new places to share with his clients. He continues to expand his own skill set, becoming one of the first instructors in the Pacific Northwest to teach rebreathers; he is now certified on 10 different units as both an Instructor and Instructor Trainer. Craig now is spending most of his underwater time  on a rebreather of some kind.

Craig's work and dedication has paid off. Craig holds the highest Instructor rating with TDI , SDI and SSI.  In 2006, he was awarded the SSI Platinum Pro 5000 Diver and Instructor Award. Craig holds many Instructor certifications with SDI, SSI, TDI, IANTD and ANDI, has worked for several training agencies, and currently represents SDI/TDI as the Northwest  Regional Manager.  Craig has over 8000 dives, over 2,000 of which are rebreather dives. You can catch him most weekends underwater, somewhere in the world. 

Thom  Robbins

Thom started diving in 1987 and continues to learn even today. Diving was a natural extension to his love of the water and the creatures that you find. While he enjoys warm water, the cold water of the Pacific Northwest holds his passion. As an avid photographer, the clear cold waters we enjoy here are the home of some of the most beautiful creatures. He is always looking for a great shot of what the cold water holds. One of Thom’s passions is helping people to learn how to safely pursue their own love of the water. If not teaching, you can usually find him looking for that perfect shot at one of the many dive sites in the area. 

Andrew Hassard

 Andrew began diving in 2009 and quickly immersed himself in further training until he became an instructor in 2014. He has also become an avid underwater photographer, traveling the globe in search of the perfect critter photos - Australia, Indonesia, Philippines, Fiji, Bonaire, Hawaii, and British Columbia have been frequent destinations. Shark encounters are a particular favorite, including dives with great whites in South Africa, walking sharks in Raja Ampat, and tigers & hammerheads in the Bahamas. 2019 started with sea lions off Hornby Island BC and ended with salt-water crocodiles in Banco Chinchorro, Mexico. A patient teacher, Andrew enjoys introducing students to the freedom of underwater adventures.

Dave Boyovich

David enjoys taking new divers out on local dives and teaching them how to have a good, successful, and enjoyable diving experience. David believes that his over 20 years of experience in teaching and competing in Martial Arts are an  asset in teaching others to dive. David enjoys diving ship wrecks, Canada's incredible walls, and playing with sea lions. In the future, David plans to get closed circuit rebreather certified, get some more warm water dives in, and expand on his instructor certifications.


Bryan Griffin

Bryan has always been quite fond of the water and in 2003 he dipped into the cold quarries of central Illinois and became a certified diver. He has been diving in some spectacular places including Tahiti, Iceland, Zanzibar, and Madagascar as part of his effort to continue building experience. When Bryan's not helping others grow their experience and confidence underwater you can find him exploring deep wrecks in the lake or searching for lost treasure at Cove 2. 


Mona Willemsen
         Travel Manager

Mona started diving in the early 1990's, and has traveled extensively all over the world. She enjoys seeing new places, good friends and laughing ( a lot!).Mona is at SW most days during the week, and driving the kids to sports in the evening and weekends. The rest of the time you can find her on a plane to some distant dive location!

Paul Yahnig
         Course Director Instructor

Paul started diving in January of 2013 after wanting to dive for most of his life.  He can usually be found diving somewhere along Alki or Redondo if he is not in the water teaching on a weekend. His favorite cold water dive destination is God's Pocket Resort in Canada where both the visibility and life is amazing, and the dives are fun and challenging. Traveling is another of his passions and Paul always tries to include dives in exotic and interesting places.  Some of the more exotic places Paul has dove at include Socorro, Thailand and Iceland.  

Don Clemmer

Don has been in the water his whole life, and after spending many years hiking and snowboarding in the mountains of the northwest, he realized he was neglecting a huge part of Washington state and got his SCUBA certification in 2013.  Since then, he's been diving in Palau, British Columbia and with the giant mantas in Socorro Mexico, but the vast majority of his dives have been right here in the home waters of Puget Sound and the fascinating underwater wilderness just beneath the surface.

Chris Wells


Long time diver Chris Wells earned his first diving certification in 1983 in New York. Growing up on the East Coast, Chris' earliest diving adventures involved exploring many of the shipwerecks off  New York and New Jersey.  Chris later moved to the Pacific Northwest, earning his first Instructor rating with NASDS in 1995, and taught here at Silent World.  Chris has extensive experience exploring shipwrecks around the world and had dove Truk ( Chuuk) and Bikini Atoll, as well as many of the more famous wrecks in the Pacific Northwest.

These days, Chris is actively teaching all levels of scuba classes, from Open Water through Advanced Nitrox and Decompression Procedures.

Most weekends, you will find Chris on a beach either fresh out of the water or getting ready to go under it!!

Corey Regen

Corey started diving in Sept 2014.  As a youngster, he was always fascinated by Jacque Cousteau and his extraordinary underwater explorations.  His love of nature and curiosity for everything above and below the water has lead him to become certified as a Dive Master.  Corey has extensive experience diving in the Puget Sound along with taking several dive trips to Canada, Mexico, and the Caribbean Islands.    He loves to share his experience and enthusiasm with new and veteran divers alike.

Miho Kawamura

Miho has always been a water baby. Swimming in a pool at 3years old and competitively swimming and surfing throughout her life, lead her to become very comfortable in the water. She became a certified diver in the summer of 2013. She loves to travel and also tries to combine diving if there’re any diving opportunities. She enjoys weekend dives in the Puget Sound, and Hood Canal with her camera. Other favorite dive locations are Raja Ampat, Maldives, Okinawa, Mexico, Caribbean, God’s Pocket (Canada), Jamaica, and her tub.
When she’s in town, you’ll usually see her with her black dog, “Roxy” because she loves being by the water too.
