Colliers begins

Our name originated in Australia, where Colliers International was founded through the collaboration of three property services firms in 1976. We are named in honor of Ronald Collier, who was a chartered surveyor and respected mentor to the founders, Robert McCuaig, Bill McHarg and George Duncan. This photo was taken in the late 1970s at our first national sales conference.

US and Canada join Colliers
The Colliers family grows

In 1984, Colliers International joined forces with Macaulay Nicolls Maitland, leading the shift in our industry from regional real estate companies to global services organizations. This prompted MNM to change its name to Colliers Macaulay Nicolls and later to Colliers International. CEO John McLernon led the charge to form partnerships worldwide; Colliers is now in 522 offices in 62 countries.

Our People

Our professionals are dedicated to creating strategic partnerships with our clients. Through careful listening and a system of uncovering client needs, we understand the subtle business drivers behind key real estate decisions. We design truly customised services to transform real estate—often one of the largest expenses for a business—into a competitive advantage. Ultimately, our goal is to accelerate our clients' success.

Our Structure

Most real estate firms are either loosely associated networks, or tightly controlled around a corporate structure. Colliers International is based on an enterprise model, unique in our industry, which offers the resources of a singular global platform and accountability through majority ownership and governance. This is balanced by flexibility and equity at the local level, which empowers our managers and local professionals to respond nimbly to the changing needs in their marketplace.

Our Values

Service, expertise, community and fun form the core of who we are. These values guide how we live and work, helping us create memorable experiences for our clients and accelerate the success of everyone we touch.

When property services are guided by shared values, our teams perform at a higher level, creating lasting personal connections among our colleagues, clients, and the communities we serve.

We create positive, memorable experiences by exceeding expectations both in business outcomes and in personal interactions. Integrity, ethics and empathy guide every interaction and define our service approach with clients and colleagues.

We pride ourselves on building and sharing expertise in order to create success for our clients and our people. Our passion for continuously expanding our knowledge base enables us to take a fresh and imaginative approach to everything we do.

We are deeply committed to the communities within which we operate, and to building sustainable business practices, environments and workplaces. We show compassion for those in need and we value and respect each other's differences and individuality.

We are serious about our work but don't take ourselves too seriously. We value an optimistic, energetic and dynamic work environment that emphasizes social as well as business interaction. We are successful because we enjoy what we do.
