Private Portfolios

Private Portfolios was founded in 1984 as a California-based registered investment advisor. Managing Partners Bob Binn and Dan Binn lead the practice, joined by Financial Advisor Mark Flowers, a CERTIFIED FINANCIAL PLANNER™. The firm holds itself out as an independent fiduciary, serving individuals, high-net-worth families, and various entities from a single office in downtown San Mateo. The firm provides financial planning, investment management, and broader wealth-management services. Asset allocation and security selection are handled internally, with strategies customized to each client's goals and risk tolerance. Geography remains tightly focused on the Bay Area, where the team meets clients face-to-face and manages long-term advisory relationships. No fund commitments, co-investments, or direct-deal activity is publicly disclosed. The practice is deliberately compact: three named professionals work from the San Mateo headquarters at 424 North San Mateo Drive. No branch offices or adjacent vehicles — such as philanthropic foundations, real-estate arms, or operating companies — appear in public filings or on the firm's website. Recent operational activity is not publicly documented, reflecting a firm that has maintained the same core team and service model without structural changes. What distinguishes Private Portfolios is its strict, decades-long focus on personal planning for a concentrated local client base. The Binn family partnership structure — two managing partners with shared ownership — keeps decision-making close and succession informal, a model that prioritizes relationship continuity over asset-gathering scale.
