Tamalpais Asset Management manages approximately $262.5 million for about 261 client relationships and provides ongoing portfolio management and financial planning to individuals, trusts, endowments, qualified retirement plan sponsors, and business entities. The firm’s client base is concentrated among high‑net‑worth households and accredited investors, and the brochure indicates it does not serve non‑HNW individual clients.

The firm builds a written Investment Policy Statement for each client and typically favors passive core exposures—primarily DFA mutual funds and ETFs—while applying modern portfolio theory alongside fundamental, cyclical and quantitative analysis. TAM also implements a range of other strategies when suitable, including options, margin transactions, and allocations to liquid and illiquid alternatives (private placements and limited partnerships) for accredited investors, generally operating with discretionary trading authority.

Notable distinctions include that a firm representative maintains a broker‑dealer registration and may offer commissionable products, a relationship the brochure discloses and documents as a potential conflict of interest. The firm also requires clients to use specified custodians (Schwab Institutional and/or Interactive Brokers), may receive related research or soft‑dollar benefits, and routinely incorporates private placements and derivatives/leverage strategies—features that are less common among similarly sized team advisory firms.
