Brennan Investment Group

Brennan Investment Group is a Chicago-based private real estate investment firm specializing in the acquisition, development, and operation of industrial properties across major metropolitan markets throughout the United States. Founded in 2010, the firm's mission is to unlock the full potential of real estate investments through innovation, integrity, and expertise, aiming to provide superior value to its investors, partners, and communities by fostering enduring relationships and leaving a lasting legacy in the real estate sector.

The company's core business revolves around industrial real estate, offering services such as single-asset acquisitions, portfolio acquisitions, build-to-suit developments, speculative developments, sale-leaseback transactions, and corporate real estate management. Brennan Investment Group's portfolio strategy includes multi-tenant light industrial, industrial outdoor storage, and data center facilities, with a focus on value-add and opportunistic investments in high-growth, land-constrained markets. The firm has established itself as the second-largest privately held industrial real estate owner in the U.S.

Led by co-founders Michael Brennan (Chairman and Managing Principal) and Kevin Brennan (Chief Investment Officer and Managing Principal), Brennan Investment Group has actively expanded its portfolio. In January 2026, the firm acquired a 13-property industrial portfolio totaling over 800,000 square feet across the Chicagoland and Milwaukee markets. This was followed by the acquisition of two Class A industrial buildings in Nashville in April 2026, marking its eighth investment in that market since 2021. The firm's current portfolio spans 29 states, encompassing approximately 57-60 million square feet, with over $6.5 billion in industrial real estate acquired or developed since its inception.
