How We Started

Colliers International proudly traces its roots back to a local firm founded 1898. Today, our offices in 66 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

1926: Founded in 1926, Williams Real Estate employed just eight brokers while managing a property portfolio valued at $1.5 Million. The firm’s talent boasted significant expertise in the up-and-coming loft and industrial markets and by 1940, had established itself as a prominent New York City Real Estate firm.

1995: Positioned as a leader in the New York real estate market, third-generation Williams expands its resources and coverage to the global level, establishing a network of 1,700 real estate professionals in 85 offices across 20 countries. Closer to home, the firm adds Tri-State depth with the addition of offices in New Jersey and Connecticut.  

2008: In 2008, the firm partners with FirstService Corporation, providing the financial backing of a global powerhouse while upholding the service excellence of a time-honored and trusted local provider.

2010: FirstService Williams rebrands to Colliers International in 2010, offering a succinct international services platform and recognized brand to compete in the evolving global marketplace. Widely recognized worldwide, the rebranding effort has further expanded upon the resources, capabilities and reach of this firm’s humble beginnings.
