Laird Norton Wetherby is a wealth management and advisory firm formed in 2024 from three legacy firms, providing investment, financial planning and trust services to families since 1967.
Laird Norton Wetherby (LNW) is a wealth management and advisory firm serving families across generations. The firm's origins trace to 1967, when the Laird Norton family established a trust company to manage its own multi-generational wealth; this business opened to the public in 1979. In 2024, three firms - Laird Norton Wealth Management, Wetherby Asset Management and Filament - united under the LNW banner.
Each of the constituent firms contributed a distinct heritage. Wetherby Asset Management, founded in 1990, was built on a model that rewarded objective advice over product sales. Filament, established in 2006, was set up to provide holistic, conflict-free guidance to families with significant wealth. The combined firm operates in wealth management, investment management, financial planning, trust services and multi-generational wealth advisory.
LNW describes its approach as expert-driven and deeply personal, with an emphasis on objective, conflict-free advice. Its stated operating principle is to serve families across generations with the same care that informed its founding as a single-family office.
