Multi-Family Office

Castellano Wealth Planning

Castellano Wealth Planning is a New York-based multi-family office offering integrated tax, estate, and investment planning for high-net-worth families.

Castellano Wealth Planning

Castellano Wealth Planning operates as an independent registered investment adviser (RIA) providing multi-family office services to high-net-worth families. The firm focuses on integrating tax strategy, estate planning, and investment management into unified long-term plans. Its origins trace to the Castellano name, though public records do not disclose a founding year or specific wealth origin for the principals. The firm builds portfolios across public equities, fixed income, alternative investments, and cash — with planning-driven allocation that prioritizes tax efficiency. It does not publicly disclose direct private-equity or venture holdings, but its planning mandate suggests work with trusts, insurance products, and charitable vehicles. The geographic focus remains domestic, serving clients across the United States. No team size, additional offices, or recent operational events are publicly available from the firm. The firm's limited profile suggests a boutique operation. No adjacent philanthropic foundations or club memberships have been identified. Castellano Wealth Planning's structural differentiator lies in its planning-first model: it aligns investment decisions with estate and tax outcomes rather than treating them as separate functions. That integration, combined with RIA fiduciary standards, distinguishes it from commission-based brokers or siloed advisory shops.
