Hinsdale Associates

Hinsdale Associates

Hinsdale Associates was founded in 1965 in Hinsdale, Illinois, a wealthy western suburb of Chicago. The firm operates as a registered investment advisor (RIA) with principals Brendan F. Kenney, Thomas J. Atteberry, and Garry P. Kenney listed on its ADV filings. It was built to serve the investment needs of local families, trustees, and charitable organizations, drawing its client base from the durable affluence concentrated along Chicago's North Shore and western suburbs. The firm manages client assets across equity, fixed-income, and real estate allocations. Public-equity portfolios are constructed on a direct-security basis — buying individual stocks and bonds rather than outsourcing to fund managers — with a value-tilt and long holding periods typical of private-client RIAs of this vintage. The fixed-income book emphasizes investment-grade municipals, reflecting the tax sensitivities of its Illinois-domiciled clientele. Real estate exposure comes through direct property holdings rather than REIT funds. The firm does not advertise venture capital, private equity, or hedge fund capabilities; it is a pure long-only, traditional asset manager. ADV filings from 2024 indicate a team of roughly 15 professionals, including several investment-advisor representatives operating under the firm's registration. Hinsdale Associates has not expanded beyond its single Hinsdale office in nearly six decades — a deliberate structural choice that keeps the firm small, relationship-driven, and free of the asset-gathering pressures that come with multiple locations. Adjacent vehicles or philanthropic arms have not been publicly disclosed. In January 2025, the firm filed its annual Form ADV amendment with the SEC, confirming continuity of its core advisory team and unchanged fee schedules. What differentiates Hinsdale Associates structurally is its staying power as a single-office, suburban RIA that survived six decades without merging, selling to a consolidator, or converting to a multi-family-office platform. This architecture forces a discipline few peer firms maintain: every client is a known local relationship, and the investment committee answers directly to those clients without the intermediation of a national compliance infrastructure or a home-office product menu.
