Williams Kastner is pleased to announce the relocation of its Seattle office to a newly designed space in downtown Seattle, effective September 8, 2025. The firm, which has been a cornerstone of the Pacific Northwest legal community since 1929, has been located in Two Union Square for over 30 years and consolidated its Seattle office from two floors into one with a more modern and efficient design. The new address for the Seattle office is: 601 Union Street, Suite 4000, Seattle, WA 98101.
The move reflects Williams Kastner’s ongoing commitment to evolve with the needs of its clients and the future of legal practice. The redesigned space was created with purpose and intentionality, supporting the firm’s dedication to delivering outstanding legal service in a contemporary, innovation-driven, and streamlined office environment.
“For nearly 100 years, Williams Kastner has been a trusted name in the Pacific Northwest legal community,” said Rod Umberger, Managing Partner. “Our new Seattle office is the next step in that legacy—modern, efficient, tech-forward, and built for the future of the practice of law.”
“We are excited to have a brand new, remodeled floor for our Seattle team,” said Amanda Teags, Chief Operating Officer. “Our firm collaborated with Burgess Design, Freeform furniture, and Gateway Construction Services to create a modern space that fosters workflow and movement throughout the office. It has been an important strategic goal to create a new workspace for our Seattle office. We look forward to hosting our current and future clients in our new space.”
