Frequently asked questions

Who runs investment decisions at Ensign Advisory Partners?

David Whitman, son of founder Martin J. Whitman, is the known principal overseeing the family office. No other named investment professionals have been publicly identified. The office appears to maintain a lean structure with family-led decision-making and external administrative support.

Where does the underlying wealth come from?

The wealth originates from Martin J. Whitman's career as a deep-value investor. He founded Third Avenue Management in 1986 and built the Third Avenue Value Fund into one of the most recognized names in distressed and value investing. His personal wealth was generated through equity ownership in the management company, carried interest, and co-investment alongside his funds over six decades.

Does Ensign Advisory Partners operate like a venture capital firm?

No, Ensign Advisory Partners does not pursue venture capital. The family office invests in public equities, private equity, and real estate with a deep-value and special-situations orientation — consistent with the investment philosophy Martin J. Whitman articulated throughout his career. Venture-stage technology companies are not a known part of the portfolio.

Is Ensign Advisory Partners related to Third Avenue Management?

Ensign Advisory Partners is a separate family office entity for the Whitman family. Third Avenue Management was the public mutual fund company Martin J. Whitman founded and led. After a series of restructurings and Whitman's departure from day-to-day management, Third Avenue was sold to AMG. The family office has no ownership connection to the current Third Avenue Management.

Does Ensign Advisory Partners manage outside capital?

No. Ensign Advisory Partners is structured as a single-family office managing only Whitman family capital. It does not accept outside investors, does not report AUM publicly, and maintains an intentionally low profile. This distinguishes it from the multibillion-dollar mutual fund platform Whitman built at Third Avenue Management, which served retail and institutional investors.
