Callan Family Office

What Callan Family Office does

Callan Family Office is a Philadelphia-headquartered, SEC-registered multi-family office founded in February 2022 that serves ultra-high-net-worth families, foundations, endowments, and single-family offices with $25 million or more in investable assets. The firm operates as a partner-owned, fiduciary-only platform with no outside private equity investment, structured around 23 partners and an 11-50 employee base. As of December 31, 2025, the firm managed more than $10 billion in assets across 73 clients, achieved entirely through organic growth.

The platform is anchored in institutional-quality investment management delivered through an open-architecture, core-satellite approach with quantitative risk management and a focus on after-tax, net-of-fee results. The proprietary Foundations 360 five-step planning methodology (Discovery, Envision, Counsel, Apply, Review) coordinates legacy planning, tax strategy, private banking and trust coordination, financial administration, business and transaction advisory, philanthropic consulting, and the Endure family governance program (delivered via an exclusive partnership with Insights Squared Consulting Group). The technology stack includes Addepar for consolidated daily portfolio reporting, SUBSCRIBE for alternative investment operations, and the Aris Investing-powered Tax Overlay Management Program for household-level tax-loss harvesting and direct indexing. Exclusive research and due diligence access is provided through a strategic licensing relationship with Callan LLC, an institutional consulting firm with $3 trillion in assets under advisement.

Revenue is generated through investment advisory fees (assets-under-management based) plus fees on integrated tax, legacy planning, philanthropic, and consulting modules, with a customized quote-based pricing model. The go-to-market is partner-led and relationship-driven, combining direct outreach, referrals, and earned media visibility (CNBC, Bloomberg, Forbes/SHOOK, InvestmentNews). The firm completed its first inorganic move in March 2026, integrating the team from Clarity Family Offices to expand multi-generational wealth consulting capabilities.
