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

Since its inception in 1920 as Lanard & Axilbund, to the global alliance forged with Colliers International in 1994, our firm has consistently pursued a disciplined approach to growth, with a view to creating a superior level of service for our clients. 

Combining our services under one global real estate services brand in 2010 was the next step in the evolution of our business, creating exciting opportunities for us and our clients today and for years to come and signifying the completion of our integration into a truly global platform with a breadth and depth of services that enables us to meet every one of our clients’ commercial real estate needs, whether it is in our local coverage region of Pennsylvania, New Jersey and Delaware or on the other side of the world.

Today, Colliers International is the third largest commercial real estate services company in the world with 12,300 professionals operating out of more than 522 offices in 62 countries.  Colliers focuses on accelerating clients’ success by seamlessly providing a full range of services to real estate users, owners and investors worldwide, including corporate solutions, brokerage, property and asset management, hotel investment sales and consulting, valuation, consulting and appraisal services, mortgage banking and research.  The latest annual survey by the Lipsey Company ranked Colliers International as the second most recognized commercial real estate firm in the world.
