Frequently asked questions

Who runs investment decisions at The Colony Group?

Michael Nathanson serves as Chairman and CEO, overseeing the firm's strategic direction. Investment policy is executed through a centralized investment committee, with portfolio construction delegated to individual advisor teams who tailor allocations to each client's tax and estate circumstances. Specific members of the investment committee are not publicly prominent in the firm's external communications.

Is The Colony Group structured as a single family office or a multi-family office?

It operates as a multi-family office and wealth management firm serving numerous high-net-worth families, not a single-family office tied to one source of wealth. The firm's growth has been fueled by acquiring independent advisory practices and integrating them into a unified platform under the Focus Financial Partners umbrella.

How is The Colony Group related to Focus Financial Partners?

Focus Financial Partners, a publicly traded partnership of wealth management firms, acquired a majority equity stake in The Colony Group. This structure provides the firm with permanent capital for acquisitions and continuity planning while allowing The Colony Group to maintain its brand, leadership, and operational independence—a model Focus replicates across its network of partner firms.

What investment stages or asset classes does the firm typically target?

The Colony Group constructs portfolios across public equities, fixed income, hedge funds, private equity, and venture capital, typically through third-party fund managers rather than direct company investments. The firm emphasizes after-tax returns and integrates investment management with estate and tax planning, making it a holistic allocator rather than a stage-specific venture investor.

Does The Colony Group participate in fund commitments or only direct deals?

The firm primarily accesses private markets through fund commitments to external managers rather than direct company investments. Its multi-family office model aggregates client capital to access institutional-quality private equity and venture capital funds, though specific fund relationships are not publicly disclosed.
