Dominion Portfolio Management

Dominion Portfolio Management

Dominion Portfolio Management was founded in 1991 as a registered investment adviser in Dallas, Texas. Michael L. Lasser, who serves as Chief Investment Officer, built the firm around a concentrated, long-only equity strategy that draws from the Graham-and-Dodd value tradition. The firm does not disclose aggregate assets, but its regulatory filings and equity holdings suggest a managed pool in the mid-nine-figures, deployed almost exclusively in publicly traded common stocks that the firm intends to hold for extended periods. The firm runs a highly focused portfolio, typically concentrated in 10 to 20 positions at any given time. Its public 13F filings reveal persistent, multi-decade allocations to financial services, real estate, energy, and transportation infrastructure. Confirmed long-term holdings include Bank of America, Berkshire Hathaway, Texas Pacific Land Corporation, and Union Pacific (per SEC filings, 2025). The approach avoids private markets, venture capital, and fund-of-funds structures. Instead, Dominion treats its public equity positions much like a private equity portfolio — buying entire business franchises where it perceives a durable competitive moat and a discount to intrinsic value, and holding through cycles unless the thesis breaks or the discount closes. The firm operates leanly, with no known additional offices or affiliated vehicles. No dedicated philanthropic foundation or co-investment club structures appear in public records. In recent years, SEC filings show the portfolio has added exposure to select energy-transition infrastructure names, maintaining the same buy-and-hold posture as its legacy positions. Dominion's structural differentiator is duration discipline paired with public-market liquidity — an architecture most associated with family capital pools, not regulated asset managers. The firm answers to no outside LP redemption cycles, has no marketing deck, and trades infrequently. The governance structure, with Lasser as the central investment decision-maker since founding, eliminates committee drift. This makes Dominion functionally closer to a permanent-capital vehicle than a conventional RIA.
