Congress Asset Management Company

Gregg O'Keefe serves as President and Chief Investment Officer, a role he has held since 2010 (per the firm's official communications). He leads a co-located team of portfolio managers and analysts in Boston who operate under a centralized research and decision-making structure. All strategies follow the same fundamental equity process, with position sizing and sector weights determined by analyst conviction rather than benchmark constraints. Paul Zettl, the firm's Chairman and founder, remains involved in strategic oversight.

The firm relies on proprietary fundamental research rather than Wall Street consensus. Analysts screen for companies with high and sustainable returns on invested capital, durable competitive moats, and management teams with disciplined capital-allocation histories. Ideas are stress-tested through direct company engagement and forensic accounting review—the team historically conducts hundreds of management meetings annually. The research process filters for earnings quality, avoiding companies where reported growth masks deteriorating underlying economics.

The firm operates primarily through institutional separate accounts and intermediary-distributed managed-account platforms. This structure gives clients direct ownership of underlying securities and the ability to customize guidelines, tax management, and exclusion screens. While the firm maintains a limited number of pooled vehicles for smaller investors, its deliberate capacity discipline and concentrated strategy design favor the separate-account model.

Congress Asset Management runs concentrated portfolios—historically 30 to 40 positions per strategy—which marks a deliberate departure from the over-diversification common among large-cap growth peers. The firm's internal research suggests that most of its excess return has come from high-conviction positions sized well above benchmark weights. This concentration requires both client tolerance for tracking-error divergence and a research process capable of justifying oversized bets through deep fundamental work rather than momentum-chasing.

Yes. The firm is independently owned by its senior investment professionals and operating executives, with no parent company, insurance balance sheet, or multi-affiliate holding structure. This governance model has allowed the investment team to maintain strategy capacity limits and avoid the product-proliferation pressures that often dilute focus at larger asset-gathering platforms. Ownership stakes are held by key portfolio managers and research staff, aligning their economic interests with long-term client outcomes.

The firm tends to underweight or exclude capital-intensive cyclical sectors—materials, energy, and traditional heavy industrials—where sustainable competitive advantages are harder to identify and returns on capital are structurally lower. It also historically avoids highly regulated utilities and telecoms, preferring technology, healthcare, and financial-services businesses where management decisions more directly drive compounding outcomes. The explicit avoidance of commodity-exposed sectors is a structural feature of the earnings-quality screen rather than a tactical call.

In January 2021, Lagan Srivastava was appointed CEO, assuming operational and business-management responsibilities (per the firm, January 2021). Gregg O'Keefe retained the President and CIO titles, preserving continuity in the investment function. Paul Zettl, who founded the firm in 1985, continues as Chairman. This separation of investment leadership from firm operations is a deliberate architecture choice that protects the research team from administrative distraction while allowing the CEO to focus on distribution, talent, and infrastructure.
