About

The firm provides discretionary investment management and financial planning to individuals, trusts, and estates and acts as a fiduciary to its clients. It manages approximately $292 million in discretionary assets and offers both ongoing wealth management and stand‑alone financial planning engagements.

Portfolios are built primarily with exchange‑traded funds and low‑cost diversified mutual funds, though the firm may also use individual stocks, bonds, options, margin transactions and closed‑end funds to implement strategies. The investment process draws on fundamental, technical, cyclical and charting analysis and can include shorter‑term trading alongside longer‑term holdings to address client objectives, tax considerations and rebalancing needs.

Noteworthy features include a small advisory team managing a relatively large pool of discretionary assets and an institutional custody relationship that provides technology and operational support. In addition, the firm discloses that its principals also provide separate tax and accounting services and are licensed to sell insurance — activities that generate outside compensation and are managed under the firm’s code of ethics and disclosure policies.

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.
