Who We Are

Who We Are

A group that’s best in class with a common passion: Helping you succeed.

We are so much more than your typical accounting firm. Founded in 1964 by Ann Vine, who was one of the first female CPAs in Washington State, we have always embraced change and innovation. Our clients are never a number, they are a name, a face, a story, and we want to help them build a legacy.

Our team’s strength comes from a combination of seasoned professionals working closely with recent graduates; leveraging the wisdom of experience while always looking to the future. This unique mix allows us to keep our firm small enough to form relationships with each client, while offering a full complement of resources and specialists for even the most complex accounting work.
