About
The firm serves primarily individual clients and also works with trustees, estates, trusts, charitable organizations, and business clients, offering financial planning, retirement-transition planning, and investment advice. In addition to investment and retirement services, the adviser provides tax preparation and planning and offers bookkeeping and payroll services to business clients as part of its fee‑for‑service tax practice.
The firm’s investment work emphasizes long‑term planning and fundamental security analysis, with recommended vehicles that include mutual funds, ETFs, individual stocks, bonds, CDs and U.S. Treasuries as appropriate for client goals. Advice is provided on a non‑discretionary basis — clients review and authorize transactions — and custody is maintained with third‑party custodians (the bulk of client assets are held at a major institutional custodian).
Compared with many peers, the firm combines a substantive tax and accounting practice (the adviser is an enrolled agent and spends a large portion of time on tax services) with investment advisory work, and routinely serves charitable and corporate/business clients. The firm generally operates on hourly and fixed maintenance fees rather than relying on percentage‑of‑AUM billing, does not take custody of client assets, and does not earn commissions on recommended custodial platforms.

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 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
