Frenzel echoed this sentiment: “Combining our resources and experience with Capstone’s expertise and existing network of offices will enable us to enhance the services we provide our clients in the Lynden and Snohomish communities.”

This partnership marks another significant step in Capstone's mission to expand its service offerings and reach while remaining steadfast in its commitment to local engagement and trust. Clients of North Star Tax & Accounting can expect a seamless practice transition over the next few months, including during the upcoming 2026 tax season.
