Longfellow Investment Management Co.

Longfellow is a privately held investment advisor, not a single-family office. Its ownership structure is not publicly disclosed, and no individual or family is named as controlling principal.

The firm focuses exclusively on fixed-income securities, including investment-grade corporate bonds, municipal bonds, mortgage-backed securities, and structured credit products. It does not manage equity or alternative asset portfolios.

The firm serves institutional investors such as pension funds, foundations, endowments, and family offices. It also manages assets for pooled investment vehicles and separate accounts.

The firm relies on fundamental credit research, macroeconomic analysis, and relative value trading. Its team evaluates bond issuers, sectors, and yield-curve positioning to construct portfolios.

No. While it counts family offices among its clients, Longfellow is structured as an SEC-registered investment advisor in the asset management category, not a single-family or multi-family office.
