About

Keystone Wealth Advisors, Inc. serves individuals (including high‑net‑worth and non‑HNW clients), pension and profit‑sharing plans, trusts, estates, charitable organizations and small businesses, offering personalized financial planning, investment management, and ERISA plan advisory services. The firm is fee‑based and provides asset management and hourly financial planning without selling commission products, overseeing roughly $201.35 million in client assets with a small advisory team.

Keystone creates an Investment Policy Statement for each client and tailors strategies to stated objectives, risk tolerance and time horizon, typically using mutual funds, separately managed accounts and outside sub‑advisors. The firm conducts quarterly reviews but operates predominantly on a non‑discretionary basis—documenting recommendations and obtaining client approval before executing individual trades.

What is distinctive is the firm’s overwhelmingly non‑discretionary asset base (discretionary assets reported as $0 and non‑discretionary $201,352,666 as of April 30, 2026), a configuration that is uncommon among peers and consistent with its frequent role as a limited‑scope ERISA 3(21) advisor and participant education provider. Ownership includes a licensed CPA and the firm does not routinely vote client proxies, leaving voting to clients unless proxy assistance is requested.

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.

Find your advisor

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
