About
The firm provides financial planning and portfolio management to individual and high-net-worth clients, covering retirement planning, cash flow analysis, estate planning, insurance review and college funding. It manages roughly $18 million for a small client base and offers continuous supervisory services tailored to individual circumstances.
Advice is delivered on a non‑discretionary basis: the firm makes recommendations and arranges trades only with client approval. Investments are limited to mutual funds, exchange-traded funds, certificates of deposit and commercial paper, with a buy‑and‑hold orientation, periodic rebalancing, and analysis that draws on both fundamental and technical sources.
Two features that distinguish the firm from many peers are its primarily non‑discretionary asset management model and its avoidance of percentage‑of‑AUM fee billing, instead using hourly or flat fixed fees for planning and management. The firm is fee‑only, has operated since 1990, does not require a minimum asset level to engage, and does not charge performance‑based fees or maintain material outside business affiliations.

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
