About
H.C. Denison Co. provides ongoing portfolio management and investment advisory services to individuals, high‑net‑worth clients, charitable organizations, and business entities, typically documenting client goals and risk tolerances in an Investment Policy Statement. The firm reports about $310 million in discretionary assets across roughly 343 client accounts and maintains an account minimum (generally $25,000).
The firm employs a mix of analytical methods — including charting, cyclical, fundamental, quantitative, modern portfolio theory, and technical analysis — and pursues a long‑term trading approach while offering discretionary authority to implement client portfolios across mutual funds, fixed income, ETFs (including precious metals), real estate funds, annuities, TIPS, and select non‑U.S. securities. H.C. Denison requires clients to use a specified broker‑dealer/custodian and discloses that it may receive research or other soft‑dollar benefits from custodians and broker‑dealers.
Notably, several supervised persons are registered representatives of an affiliated broker‑dealer and hold insurance licenses, and the firm discloses that these activities can result in commissionable sales and related conflicts of interest that are documented for clients. The brochure also discloses prior regulatory actions and consent orders related to broker‑dealer registration and pre‑registration transactions (including matters in 2009, 2010, and 2022) that have been resolved with fines and registration remediation.

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
