About
Sierra Financial Advisory serves primarily individual and family clients and also manages small business retirement plans, trusts, estates, and charitable accounts, with roughly $145 million in assets across about 173 client relationships. The firm provides financial planning and ongoing investment supervisory services, largely on a discretionary basis, and maintains a $500,000 household minimum for advisory management while admitting smaller accounts on a case-by-case basis.
The firm’s process begins with financial planning and constructing personalized portfolios aligned to client risk tolerances, using five model mixes ranging from Very Conservative to Aggressive. Portfolios rely mainly on mutual funds and ETFs selected for downside protection, together with occasional individual stocks and bonds subject to fundamental analysis; SFA follows a long-term, no-market-timing approach and monitors portfolios for asset allocation and rebalancing.
Notably, Sierra combines percentage-of-AUM advisory relationships with a smaller number of commission-based, non-discretionary transactions—typically fixed annuities and long-term care insurance—and both principals hold insurance licenses in California, Washington and Oregon and may transact insurance business for clients. The firm discloses these commission arrangements and related conflicts, maintains limited power-of-attorney for trading (but not custody), and reports quarterly account information and aggregate reporting across custodians.

Advisors at this firm
Not sure where to start?
We'll help you think it through—whether you ultimately need an advisor or not. Warmer helps you compare advisors clearly, so you can choose with confidence.
For advisor listings, we rely on sources including public filings and data provided by advisors, and we cannot guarantee that all information is current or accurate. Advisors are independent and may not have reviewed or updated this information. Please review an advisor’s Form ADV and do your own diligence before deciding whether to work with them.
Advisor matching and introductions are provided by FinanceHQ LLC (“FHQ”), a wholly-owned subsidiary of Warmer and an SEC-registered investment advisor. We receive compensation from certain participating advisors for introductions or referrals. This creates a conflict of interest because we have an incentive to recommend advisors who compensate us, including those who pay us more. You pay no fee to use our matching service, and advisor fees are not increased because of a referral or introduction. We do not review the ongoing performance of advisors, manage or hold assets, guarantee performance, or provide advice about specific investments.
By using our service, you agree to our Terms of Service and Advisory Agreement, and acknowledge our Privacy Policy. Please review FHQ’s ADV Part 2A and Form CRS. Logos provided by Logo.dev
