Karr Tuttle Campbell

Established in 1904, Karr Tuttle Campbell ("KTC") is one of Seattle’s oldest full-service law firms, serving the business and litigation needs of individuals, organizations, and leading businesses throughout the Pacific Northwest. Based in Seattle, Washington we have a second office in Portland, Oregon. Well into our second century of service, we remain committed to the traditions of providing excellent legal services, innovative approaches, meeting the challenges of a global marketplace, “greener” work practices, and supporting our community. KTC has long been a proponent of diversity, equity, and inclusion, dating back to 1936 when it hired Muriel Mawer, who was a member of the firm for decades and one of the first female senior partners at a major Seattle law firm. Today, we are dedicated to increasing firm diversity, and to be a proud to be supportive of LGTBQ+ and gender equity. Learn more about our firm at
