About Us

Harbour Accounting was founded by Kyle and Summer Thomsen, a husband-and-wife team dedicated to providing small and medium businesses with personalized, efficient, and reliable accounting solutions. As residents of Gig Harbor, we created Harbour Accounting to support our local community with approachable services that simplify finances and empower growth. We serve clients in Gig Harbor, Tacoma, and across Western Washington.

Our Story
As a family, we believe that business should be personal. After Kyle earned his CPA, we saw the opportunity to combine his accounting expertise with Summer’s operational and project management strengths to create an accounting practice that prioritizes trust, clarity, and practical solutions. We founded Harbour Accounting to serve Gig Harbor, Pierce County, and Western Washington with bookkeeping, tax preparation, advisory, and fractional CFO services designed for where you are – and where you want to go.

We’re here to take the stress out of your accounting, clean up your books, streamline your operations, and help your business thrive. When you work with Harbour Accounting, you’re not just getting accountants – you’re gaining a dedicated financial partner invested in your success.

Let us show you what “Accounting Built For You” truly means.
