Ensign Advisory Partners
Ensign Advisory Partners manages the Whitman family fortune built by deep-value investor Martin J. Whitman, founder of Third Avenue Funds.
Ensign Advisory Partners
Ensign Advisory Partners was formed to steward the family capital of Martin J. Whitman following his long tenure running Third Avenue Management. Whitman became known as one of the foremost distressed-debt and deep-value investors of his generation, authoring The Aggressive Conservative Investor and running the Third Avenue Value Fund for decades. The family office separates personal wealth management from the public-facing mutual fund complex, investing across a concentrated set of public equities, private equity interests, and real estate. The firm has been associated with holdings in companies such as Brookfield Asset Management and Navistar International, reflecting Whitman's preference for asset-heavy, undervalued businesses. The investment posture skews toward special situations, distressed opportunities, and direct equity stakes. Geographically, the portfolio spans North America and select international markets, with real estate investments concentrated in major US metropolitan areas. As a single-family office, Ensign Advisory Partners does not report assets under management publicly. Third Avenue Management, before its eventual restructuring, oversaw approximately $20 billion in peak assets, but Whitman's personal wealth was generated separately through carried interest, equity ownership in the management company, and personal co-investment alongside his funds. The family office likely deploys capital in the range of several hundred million dollars. No team size or office locations are publicly disclosed. In recent years, the firm was referenced in SEC filings related to Whitman family holdings, including a 13D filing showing a significant stake in a publicly traded company through the Ensign entity. What distinguished Whitman's approach — and by extension the family office — was his focus on "safe and cheap" investing. He sought companies with strong balance sheets, real assets, and management teams he trusted, often holding positions for decades. Ensign Advisory Partners continues to reflect that philosophy, avoiding leverage, derivatives, and short-term trading. The office is not known to participate in venture capital, startup investing, or momentum-driven strategies, setting it apart from many contemporary family offices that chase technology exposure. Martin J. Whitman passed away in 2018. His son, David Whitman, has been associated with the family's investment activities and is presumed to oversee Ensign Advisory Partners. No named CIO or managing director has been disclosed publicly. The succession structure appears to keep investment decision-making within the immediate family, with outside counsel and administrative support from a small dedicated team.

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.
