Harrington Investments
Harrington Investments was established in 1982 by John Harrington. The firm originated from the Harrington family’s commitment to socially responsible investing and now extends that mandate to external clients. The firm deploys capital across public equities screened for ESG criteria, private alternative investments, and community-development vehicles. It participates in activist and mission-related strategies. Confirmed activity includes membership in the Shareholder Rights Group and active filings through the Interfaith Center on Corporate Responsibility. Geographic reach centers on North America with additional exposure through Ceres Coalition networks. The team includes six named professionals. Adjacent vehicles comprise the Eleos Foundation, the Rose Foundation for Communities and the Environment, and the Land Trust of Napa County. John Harrington maintains membership in the Green Century President’s Circle. The firm’s structure integrates family ownership with external client mandates under a single regulated entity, allowing direct shareholder engagement without separate fund vehicles.
