Sullivan & Serwitz Family Office

Sullivan & Serwitz Family Office

Sullivan & Serwitz Family Office was established in Los Altos, California, to serve a small constellation of families with coordinated wealth management rather than product distribution. The firm's founding principals remain largely unpublicized, consistent with a practice built on direct referrals within concentrated Northern California professional networks. The office's defining brief is generational continuity: it couples investment advisory work with estate planning, tax strategy, and philanthropic structuring, suggesting the underlying client base is composed of families who have already experienced a liquidity event and are now focused on preservation and succession. The firm's investment approach spans multiple asset classes — public equities, fixed income, private alternatives, and real estate — deployed through both direct management and external manager selection. Geographic focus appears concentrated in North America, though the portfolio construction details and specific manager relationships are not publicly disclosed. Without a marketing footprint, Sullivan & Serwitz likely accesses private opportunities through long-standing GP relationships and co-investment channels typical of networked, low-profile multi-family offices in the Bay Area. No named portfolio companies or fund commitments appear in the public record. The team includes professionals with backgrounds in estate law, tax advisory, and investment management, though exact headcount is not published. The firm maintains a philanthropic connection to Junipero Serra High School, pointing to Catholic institutional ties within its client community. A dedicated foundation vehicle does not appear to exist independently; instead, charitable giving is handled as an integrated component of the family balance sheets the firm oversees. In recent years, the office has not announced any new principals, vehicle launches, or major mandate shifts that entered the public domain. Sullivan & Serwitz's structural differentiator is its aversion to scale. In a region crowded with firms that feed on venture liquidity and chase AUM milestones, this office appears designed to remain small and internally funded. That posture creates both a cultural alignment with families who value discretion and a constraint — the firm likely lacks the sourcing infrastructure of larger multi-family offices, depending instead on the personal networks of its principals and clients to fill a deal pipeline that remains invisible to outsiders.
