About
The firm provides portfolio management and related financial planning services to individual investors, primarily implementing portfolios made up of mutual funds and exchange-traded funds and offering managed account programs and IRA rollover recommendations. Clients receive written portfolio evaluations and periodic account reports, with the firm describing regular supervision designed to meet individual objectives.
The firm follows a long-term purchase approach and uses fundamental, technical, and cyclical analysis to guide investment selection, typically recommending holdings intended to be held at least one year. It operates largely on a non-discretionary basis—clients retain authority over trade executions, broker selection, and proxy voting—and may choose quarterly, semi-annual, or annual review schedules.
Compared with many independent advisers, the firm’s combination of a small client base and roughly $12 million in AUM with primarily non-discretionary management is uncommon. The brochure also highlights retirement-planning credentials, an explicit fiduciary acknowledgement when advising on rollovers, limited custody only to facilitate fee deduction, and an explicit discussion of emerging risks such as cryptocurrencies.

Warmer provides personalized recommendations and introductions to independent fiduciary advisors. We do not supervise advisors, manage or hold assets, guarantee performance, or provide advice about specific investments.
Each advisor listed on our site is an independent fiduciary responsible for their own advice. Warmer may receive fees from advisors for participation or referrals; these fees are paid by advisors and do not affect the fees clients pay for advisory services.
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. Please review an advisor's Form ADV and do your own diligence before entering into an advisory relationship.
