F/B/O Services

F/B/O Services

F/B/O Services was founded by Joseph W. Roskos after his tenure leading Joseph W. Roskos & Co. at Bryn Mawr Bank Corp. The firm operates from a single office in King of Prussia, Pennsylvania, and positions itself as a conflict-free provider of outsourced family-office administration. Unlike most multi-family offices, it does not manage client investments or sell financial products, which eliminates the incentive structures common in wealth management practices. Roskos leads a team of CPAs, attorneys, and finance professionals who act as the operational layer for personal wealth structures. The firm's core work spans three areas: family-office administration and accounting, personal and business tax preparation, and bespoke specialty assignments for high-net-worth families. Rather than pursuing private equity, venture capital, hedge funds, real estate, or direct co-investments, F/B/O Services focuses entirely on the fiduciary mechanics — bill payment, entity-level bookkeeping, trust accounting, regulatory reporting, and estate-flow coordination. Its client base includes individual trustees who need support discharging their legal duties, as well as families that require full outsourced CFO and tax functions. Confirmed business-partner relationships include the Margaret Dorrance Strawbridge family and the Flagler family, for whom the firm provides administrative and officer services for foundations and related entities. Team scale and growth metrics are not publicly disclosed, though the firm participates actively in peer networks. F/B/O Services is a member of the Family Office Exchange, the Palm Beach Hedge Fund Association's family-office directory, and the Independent Trustee Alliance, where Evan Roskos holds membership. The firm maintains a foundation-services relationship with the Margaret Dorrance Strawbridge Foundation of PA II Inc., providing administration and officer support that extends its model into philanthropic governance. No adjacent investment vehicles, club-deal structures, or co-investment platforms are known to exist. F/B/O Services stands apart structurally because it has no investment function at all. Its mandate ends where asset management begins, giving it a pure-fiduciary architecture rarely seen in the multi-family-office landscape. For families whose wealth is already allocated and governed, the firm supplies the ongoing administrative and tax-compliance infrastructure without competing for investment discretion or custody of the assets.
