Dian Graves Owen Foundation

Dian Graves Owen Foundation

The Dian Graves Owen Foundation was founded in 1996 by Dian Graves Stai, a Texas healthcare entrepreneur who co-founded Owen Healthcare with her first husband, Jean H. Owen. Owen Healthcare became one of the largest hospital pharmacy management companies in the United States before its eventual sale, generating the capital base that now funds the foundation's activities from its headquarters in downtown Abilene. The foundation's capital is deployed across a dual mandate: structured philanthropic grantmaking and a venture investment portfolio. Grantmaking focuses on education, the arts, health, and human services — primarily within Texas. On the investment side, the foundation makes direct venture capital allocations and co-investments, a posture shaped significantly by President Tucker Bridwell, who also runs the affiliated family investment entity Mansefeldt Investment Corp. Bridwell's network connects the foundation to a broader energy-and-growth ecosystem; he manages MDJ Minerals, a Permian Basin mineral-interest portfolio, and maintains a long-standing investment association with David B. Miller, co-founder of the energy-focused private equity firm EnCap Investments. The foundation's venture activities span generalist early-stage and growth-stage commitments. Dian Graves Stai remains one of West Texas's most prominent civic and business figures. She was the first woman to chair the Abilene Chamber of Commerce and was inducted into the Texas Business Hall of Fame in 2016. The foundation operates alongside her personal and family interests — including her husband Harlan Stai — but maintains a distinct grantmaking rhythm through Philanthropy Southwest, a regional association of grantmakers where the foundation holds membership. The foundation's direct-investment activity, combined with Bridwell's dual role managing energy royalties through MDJ Minerals, creates a capital structure that blends endowment-style total-return objectives with active principal-led deal sourcing. What distinguishes the foundation structurally is its synthesis of a private grantmaking charter and an active, internally-directed investment program that behaves like a single-family office. Unlike most foundations of its size, which outsource investment management entirely to an OCIO or a board-directed allocation model, the Dian Graves Owen Foundation uses a compact executive structure — Stai as Founder and Chairman, Bridwell as President — to directly source and manage venture commitments. This deliberately flat architecture allows investment decisions to move at the speed of a principals' shop rather than a committee-bound institution.
