About
Fifth Set Private Wealth Management LLC is an SEC‑registered independent advisory firm that provides portfolio management, financial planning, asset allocation and related wealth management services to individuals (including high‑net‑worth clients), as well as corporations and other business entities. As of December 31, 2025 the firm reported roughly $160.3 million in assets under management across about 63 client relationships and provides both discretionary and non‑discretionary portfolio management.
The firm’s investment approach is grounded in modern portfolio theory and the efficient market hypothesis, favoring diversified asset‑class allocations over individual security selection or market timing and, when appropriate, employing long‑ and short‑term purchases and option strategies. Portfolios are customized to each client’s risk profile and investment guidelines, include mutual funds and ETFs (including funds from Dimensional Fund Advisors), and are reviewed on a regular cadence with accounts subject to at least monthly oversight by a single firm reviewer.
Several operational features distinguish the firm from many peers: Fifth Set maintains a relatively high minimum account size of $800,000 and a stated minimum quarterly fee of $2,500, uses DFA funds that align with an EMH‑based philosophy, and generally does not aggregate trades since it typically does not recommend individual securities. The firm also does not participate in wrap fee programs, does not vote client proxies on their behalf, and recommends Schwab and Fidelity custodial platforms through which it receives institutional services and fee‑debit capabilities.

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
