A Century Of Service

Bailey Onsager is a litigation firm that has been helping local and national clients protect their interests and prevail in court since 1910. From our beginning as Trefethen & Grinstead, through nearly two decades as Stafford Frey Cooper, the firm’s main office has remained in Seattle as a central hub for our individual, business and organization clients throughout the Pacific Northwest.

Our philosophy is simple: we view our practice through the eyes of our clients. We treat budgets and expenses with care. We provide individual attention, creativity, professionalism, and understanding for the client’s needs. We listen, collaborate, advise, and then act decisively. We know that complex situations need special skill and expertise, and our talented team consistently produces results that allow our clients to thrive and succeed.
