About
Sonoma Mountain Financial LLC provides wealth management, discretionary investment management, and financial planning to individuals, high‑net‑worth clients, families, trusts, estates, and small businesses. The firm constructs customized portfolios using ETFs, individual equities and mutual funds, and may incorporate separate account managers, options, or other investments as appropriate.
The firm’s investment approach emphasizes Modern Portfolio Theory and strategic asset allocation, with a long‑term orientation while allowing shorter‑term trades for rebalancing or tactical needs; accounts are monitored continuously and reviewed at least annually. Sonoma manages client accounts on a discretionary basis, may recommend securities‑backed lending when appropriate, and allows clients to impose reasonable investment restrictions.
What distinguishes Sonoma from many peers is its billing model and client education offerings: it generally relies on a fixed annual retainer rather than a percentage‑of‑assets fee and offers stand‑alone educational seminars and multi‑week financial education courses for a modest fixed fee. The firm manages a relatively small asset base and client roster, its principal brings professional experience from outside traditional finance, and it maintains an institutional custodian relationship that supplies technology and operational support.

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.
