How We Started

Colliers International proudly traces its roots back to a local firm founded 1898. Today, our offices in 68 countries are aligned under a single brand and leadership, providing our clients with best-in-class resources while maintaining our historical flexibility and local ties.

Colliers was one of the first truly global commercial real estate organizations, formed more than 30 years ago as a network of independent firms. As client needs evolved, Colliers embraced the the opportunity to build an integrated global platform of professionals and property services to meet the demand for globally consistent service, accountability and integration.

Our Local History

Colliers International’s rich Chicago history extends back to 1947 when Bennett & Kahnweiler was founded by Marshall Bennett and Louis Kahnweiler. In its early beginnings it was best known for the development of the 2,300-acre Centex Industrial Park in Elk Grove Village, IL, resulting in the firm’s reputation as an industrial powerhouse that endured for the next several decades.  To provide its clients with a more diverse set of global real estate services, the firm joined the Colliers International family in 1983 and became known as Colliers Bennett & Kahnweiler. Colliers B&K operated as a highly successful, independently owned and operated affiliate.

In early-2010, Colliers International merged with FSREA, a subsidiary of publicly traded FirstService Corporation, creating the third largest global commercial real estate services brand.  Later, Colliers International completed a partial acquisition of Colliers Bennett & Kahnweiler. We are now accelerating the success of our clients under one name, one brand, and one operating philosophy.  Colliers Chicago is owned by 22 principals and employs approximately 275 people in its two Chicago offices, including a staff of 125 property management professionals nearly 90 brokers.
