Peterson Sullivan LLP

Seattle, Washington, United States of America

A college in Sitka, a developer in Seattle, and an auto dealer in San Francisco all have this much in common: they need the oversight of a technically excellent accounting firm, they need superb business advice, and they all choose Peterson Sullivan.

We see every audit, every tax filing, every phone call as part of a much larger goal: getting to know a business so well that we become both an indispensable source of sound advice and a true servant of the client’s long-term business interests. That’s been our mission since we opened our doors in 1952.
