## About

Keith Vernon established Bristlecone Advisors in 1999. The firm began as a standalone practice and expanded into a multi-family office serving clients primarily in Washington state. It provides coordinated services that include investment oversight, tax planning, and succession support. Bristlecone deploys capital across public equities, fixed income, and alternative holdings that include cryptocurrency trusts. Confirmed positions include iShares Ethereum Trust, Grayscale Bitcoin Mini Trust, and SPDR Gold MiniShares Trust. The firm also holds Aristata Software, a Seattle-based company. Activity remains concentrated in North America with no disclosed commitments outside the region. Structures favor direct holdings and separately managed accounts rather than commingled fund commitments. The firm employs an open-architecture model and reports 150 client relationships. In October 2025 Bristlecone was acquired by Corient, a platform backed by CI Financial. Additional offices have not been disclosed. Keith Vernon previously joined Clarius Group after the founding period, creating an overlapping leadership history between the two entities. Bristlecone operates as a registered investment adviser that integrates mission-related investing mandates for clients. The acquisition by Corient introduces an external ownership layer while preserving day-to-day advisory continuity for existing families.
