Williams Kastner

What Williams Kastner does

Williams Kastner is a privately held Pacific Northwest law firm founded in 1929, headquartered in Seattle, with additional offices in Spokane and Portland and more than 65 lawyers across Washington and Oregon. The firm provides a full-service commercial litigation and transactional practice including commercial litigation, professional liability defense (for attorneys, accountants, architects, engineers, medical practitioners, and securities brokers), product liability and mass tort defense, retail and hospitality defense, labor and employment, real estate, intellectual property, estate planning, and mediation/arbitration. Its client base is primarily enterprise and institutional, including corporates in retail (Walmart), food manufacturing (ConAgra), manufacturing (Keystone RV), and professional services, alongside individuals requiring estate planning and dispute resolution.

The firm's core technology is standard legal practice management and case management software; there are no proprietary technology platforms or AI-driven products. The underlying capability is human legal expertise, executed largely through courtroom trial work — the firm averages approximately 30 jury trials per year, more than any other firm in the Northwest — supplemented by alternative dispute resolution services. Williams Kastner maintains membership in USLAW NETWORK (100+ firms, 7,000+ attorneys), providing international referral reach. Recognition includes 20 Best Lawyers in America 2026 honorees, 7 Best Lawyers: Ones to Watch, Tier 3 national rankings in Environmental Law and Construction Litigation, and consecutive Chambers USA recognition.

The business model is professional services billing: hourly fees for litigation and transactional work, contingency fees for certain plaintiff matters, and flat fees for defined services such as consultations and document preparation. The firm is sales-led, acquiring clients through professional reputation, attorney referrals, industry recognition, and direct business development, with national coordinating counsel relationships for major enterprise clients. Williams Kastner is independently owned by its equity members, with no disclosed parent company, external institutional investment, or public listing. Managing Director Rodney L. Umberger, elected in January 2023, leads the firm alongside a refreshed board elected in 2025-2026.
