About
The firm provides financial and advisory services to individuals and small businesses, including securities investment services, comprehensive financial planning, tax preparation and representation, insurance planning, college-aid planning, bookkeeping and small-business consulting. Services are delivered through seminars, face-to-face and online meetings and may include ad hoc analyses as well as ongoing portfolio reporting.
Advisory work is conducted on a non-discretionary basis: the firm provides analysis, research and recommendations while clients retain final investment decisions, and it uses methods such as charting, fundamental and technical analysis across a range of instruments and strategies. Compensation is largely transaction- and project-based, with planning billed hourly or by project rather than through a percentage-of-assets arrangement.
Noteworthy features include the adviser’s status as an enrolled agent who prepares tax returns and represents clients before the IRS, and licensure as an insurance agent through which the firm receives commissions for life and annuity products—arrangements that are uncommon among firms classified as investment managers. The firm operates as a sole proprietor offering an unusual combination of tax, insurance, college-aid and bookkeeping services alongside investment advice, and it does not take custody of client assets or trade on a discretionary basis.

Forms ADV
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
