Financial Guidance with a Local, Personal Touch

At Summit Accounting, we believe great service begins with strong relationships. Since our founding in Redmond, Washington, we’ve supported clients through life transitions, business decisions, and long-term planning with a steady hand and a warm, pragmatic voice.

We’re a boutique firm by design—referral-based, intentionally small, and built to deliver high-level expertise with deeply personalized care. When you work with us, you’re not routed through a switchboard or handed off to someone new every year. You’ll hear from real people, know who’s supporting you, and feel confident every step of the way.

Who We Serve

Our clients are  families, small business owners, and high-net-worth individuals who value clarity, confidentiality, and proactive support. Most come to us through personal introductions—because we know that trust is earned, not advertised.

Whether you're navigating a complex tax matter, planning for retirement, or scaling your business, we’ll meet you where you are—and help you move forward with insight and confidence.
