Mesirow Institutional Investment Management

Natalie A. Brown serves as CEO of the broader Mesirow enterprise. Individual investment decisions within the institutional platform are made by specialized team heads across real estate, private credit, and hedge fund strategies. The firm operates with portfolio manager autonomy within centrally defined risk parameters and asset allocation frameworks.

Mesirow operates across both models. The hedge fund group primarily constructs multi-manager fund-of-funds portfolios, while the private credit and real estate teams execute direct investments and co-investment structures. The private equity strategy includes both primary fund commitments and direct co-investment opportunities sourced through general partner relationships.

Mesirow is privately held by its senior professionals through an employee stock ownership architecture maintained since 1937. This structure means portfolio managers are meaningfully co-invested in the firm's aggregate financial performance, which tends to encourage retention, succession planning, and risk discipline — features that institutional investors view favorably compared to private equity-backed managers facing eventual liquidity events.
