  • Leavitt Group Northwest is the absolute best!

    They are a great help when getting insurance, and doubly appreciated during claims! I'm so glad they explained the coverage to us and helped us get the better insurance package, especially since we've actually had to use it. I've had multiple insurance companies and agents, and Shelli and Leavitt Group Northwest are hands down the best!

About Shelli

I believe in referral driven business.  

With over 30 years' experience in insurance and owning my own business (Cascade Insurance Agency), I hope it's our customers who share our story because of the way they are treated.   

I have never really sold insurance - I simply serve my clients with top-notch service and love being involved in our community. That's what makes my work so rewarding. And now that we've joined Leavitt Group Northwest, it's made us even better.  

It means I can now give my local clients the power of a national brokerage, with vast insurance options, while they continue to receive personalized attention, which is exactly how it should be. It's about truly listening to be able to prescribe just the right amount and type of insurance. 

 At Leavitt Group Northwest, we have access to national resources for education, insurance markets, and loss control processes. We also have our own in-house claims team to work on your behalf.  These services and our great team culture is what truly what sets us apart. 

I love our corner of the earth, Whidbey Island, WA. I've been honored to be on the Board of Directors for the Oak Harbor Chamber of Commerce, Coupeville Booster Club, and President of the Coupeville Chamber of Commerce.  

Neighborhoods served

Island County and Skagit County

    Recently, our team provided over 3,000 books to students at Crescent Harbor Elementary, a Title I school, so each child could have their own personal library. It was a special project.  

    I raised in Whidbey Island and after attending Skagit Community College, Brad and I came back to raise our two kids, Ali and Aaron.  I enjoy being outdoors and there's something magical about sitting around a campfire. I love to get out camping, gardening, jeeping, and floating the rivers with my family.  

    Our newest family addition is a darling australian shepherd/heeler mix COVID puppy we named Cooper. He keeps me on my toes!
