About

Fierston Financial Group provides discretionary portfolio management and financial planning to individuals, high‑net‑worth clients, and institutional entities such as pension and profit‑sharing plans, trusts, estates, and charitable organizations. As of December 31, 2025, the firm reported $1,035,576,610 in discretionary assets across roughly 310 client relationships and also offers stand‑alone financial planning and consulting engagements.

The firm’s investment approach is grounded in Modern Portfolio Theory and a buy‑and‑hold orientation, emphasizing diversified allocations implemented principally with no‑load (or load‑waived) mutual funds and, in limited circumstances, ETFs, individual equities and fixed income securities. Portfolios are managed on a discretionary basis after establishing a client’s investment profile and objectives, with ongoing supervision, periodic account reviews, and an inclination to avoid frequent trading.

Notably, Fierston’s asset base results in an unusually high level of assets per advisor (over $200 million per advisor), and the firm discloses that it may facilitate margin and securities‑based loans in client accounts at a client’s request, while cautioning that such borrowing is generally recommended only for specific short‑term needs rather than for additional market exposure. The firm typically requires a $1,000,000 account minimum for portfolio management (negotiable in certain circumstances) and commonly recommends a major custodian, noting receipt of custody‑related support services and the attendant conflicts of interest.

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
