About
The firm is a sole‑proprietorship registered investment adviser that offers financial planning, portfolio management, employee benefits planning, and related services to individuals, business owners and businesses; it also makes introductions to third‑party advisers. Described services include portfolio construction, asset allocation, rebalancing, tax‑aware decision making, and educational seminars and workshops on topics such as retirement planning and options strategies.
The investment approach blends quantitative analysis—using financial ratios and discounted cash flow valuations—with diversified asset allocation and index‑tracking strategies, and spans value, growth, income, small‑cap and socially responsible investing styles. The firm provides ongoing monitoring with quarterly and annual reviews, does not accept discretionary authority to manage client accounts, and uses a mix of fee arrangements including percentage‑of‑AUM, fixed and hourly charges.
What is distinctive about the firm is its participation as a wrap fee program sponsor and its explicit offering of no‑charge educational seminars and workshops, both of which are uncommon among peers. The brochure also discloses that the firm selects and refers clients to other advisers and may receive referral payments (up to 25% of a third‑party adviser’s investment management fee), an arrangement the firm identifies as a material conflict to be disclosed and managed.

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.
