About
Dean B. Duncan is an independent, sole‑proprietor investment adviser who provides discretionary portfolio management for individual clients and their IRAs, focusing on growth and income objectives. The firm serves a small number of individual (non‑high‑net‑worth) clients and reports no account minimums.
Portfolios are constructed primarily with individual securities — including closed‑end funds, ETFs, and common stocks — and are selected using both fundamental and technical analysis while cash balances are adjusted to market conditions. The adviser accepts discretionary authority, reviews accounts regularly, and provides periodic and annual performance and transaction reporting; trading activity may be higher in IRA accounts where tax treatment differs.
Distinctive features include long tenure (in business since 1974) and a business model that relies on asset‑based advisory billing rather than commissions, sales of commissioned products, wrap programs, or private fund management. The firm’s small scale, independence, and emphasis on direct securities investing rather than open‑end mutual funds set it apart from many peers in its regulatory category.

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
