About

Sigma Financial serves officer‑level executives at major public corporations, private equity partners, and retired executives, offering comprehensive financial planning that addresses investments, tax and estate planning, insurance analysis, company stock and incentive compensation, retirement preparation, and targeted engagement on special projects. The firm works as a fee‑for‑service consultant and supports implementation by coordinating with clients’ brokers, attorneys, and tax preparers rather than acting as a custodian or securities seller.

The firm’s investment approach is long‑term and conservative, emphasizing diversification, low‑cost passive vehicles, tax efficiency, and liquidity; advisers analyze each client’s total exposure—including stock options, restricted shares, and deferred compensation—using proprietary cash‑flow and simulation tools. Clients receive a written plan and ongoing advisory support (consolidated asset summaries, tax and withholding projections, and periodic review meetings) rather than hands‑on, discretionary portfolio management.

Noteworthy for a supported firm, Sigma does not provide day‑to‑day portfolio management, does not take custody of assets, and does not charge or accept percentage‑of‑AUM or performance‑based fees; the firm relies solely on client fees and reports no commission or referral arrangements. The practice also offers several practical services uncommon for a small planner (mortgage assistance, walkaway analyses for job changes, and contract negotiation support) and enforces internal trading restrictions around client employers to reduce potential conflicts.

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.
