About
The firm provides discretionary investment management to individuals, high‑net‑worth clients, and small businesses, with most current accounts held by individual clients. It manages approximately $421,000 across six client accounts and customizes portfolios to fit each client’s objectives.
Investment decisions follow a bottom‑up, fundamental analysis focused on intrinsic value and long‑term (five‑year plus) outperformance relative to broad market indices. The adviser conducts all research in‑house, does not use margin, debt, or derivatives, and explicitly avoids technical or cyclical analysis, treating permanent loss of capital rather than short‑term volatility as the primary risk.
Noteworthy operational features include acceptance of only discretionary accounts while not maintaining custody of client assets or automatically debiting fees; clients are expected to provide custodian access and pay fees directly, and the firm requires a separate advisor login to custodial portals to exercise trading authority. The adviser also discloses that a majority of their liquid personal assets are invested in a manner similar to client portfolios and recommends Charles Schwab as a custodian without receiving referral compensation.

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 referrals are provided by FinanceHQ LLC ("FHQ"), a wholly-owned subsidiary of Warmer and an SEC-registered investment adviser. We may be compensated by participating advisors. You pay no fee to use our matching service, and advisor fees are not increased because of a referral. We do not supervise advisors, manage or hold assets, guarantee performance, or provide advice about specific investments.
By using our service, you agree to the Warmer Terms of Service and FHQ Advisory Agreement, and acknowledge Warmer's Privacy Policy. Please review FHQ's ADV Part 2A and Form CRS. Logos provided by Logo.dev
