Craig Willemsen
        Instructor Trainer,
        Tech Instructor &
        Store Owner

Craig started diving in 1972 and for over 44 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 certied 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 SSI , SDI and TDI.  In 2006, he was awarded the esteemed SSI Platinum Pro 5000 Diver and Instructor Award. Craig holds many Instructor certifications with SDI, SSI, TDI, IANTD and ANDI, and has worked for several training agencies, and currently represents SDI/TDI as the Northwest  Regional Manager. He also works as an Expert Witness and Consultant for the Diving Industry. Craig has over 7000 dives, over 2,000 of which are rebreather dives. You can catch him most weekends underwater, somewhere in the world. 

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.  

Dave Boyovich
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.

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.


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.  Work and family limited Chris' diving exploits until recertifying as an Instructor in 2015.  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 Decompresion Procedures.

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