Making a difference in the New York Tri-State region

New York Tri-State region

Colliers International is the fastest-growing commercial real estate organization in the New York region. By combining the industry’s best infrastructure and innovation with diverse, recognized leaders from across the talent spectrum, the firm has the resources to assist clients via an entrepreneurial and enterprising culture that drives success each and every day. The firm’s global service platform supports and enhances metro New York’s expertise and experience, fosters the use and development of best practices and ultimately provides clients with the information and guidance for smart decision-making in the Tri-State region and worldwide.

Colliers’ roots in the New York region date back to 1926. Today, the firm serves clients through the expertise of 410 professionals, including 150 brokers, in seven offices across New York City and the outer boroughs, Long Island, northern and central New Jersey, southwestern Connecticut and Westchester County, NY. Strategic corporate moves — including the recent acquisitions of project management firms Strategic Business Solutions and Gorton & Partners, Colliers International of Long Island and the recruiting of brokerage, professional, specialty and support leaders have expanded the firm’s capabilities to office, retail and industrial tenant and landlord representation; capital markets and investment services; corporate solutions; consulting; project management; valuation and advisory and property management. Colliers now manages almost 11.5 million square feet of space in the New York metropolitan region and in 2016, concluded over 940 leasing and sale transactions totaling 13.7 million square feet.

Our legacy in New York

Since its inception as a family-run, Manhattan real estate firm nearly a century ago, Colliers International’s New York presence has evolved through organic growth, affiliate partnerships and strategic mergers and acquisitions into a full-service organization focused on exceptional client service and committed to accelerating client success through both local expertise and Colliers’ global network.

The birth of a real estate power
Colliers International’s New York office was founded in 1926 by real estate brokers Victor J. Cohen and William Silverman. Known as Williams & Company, the firm specialized in the loft and industrial markets, providing asset management and advisory services to banks, landlords and investors, and eventually becoming partial owner of several of the buildings they managed.

Over the next few decades, Williams & Company (now called Williams Real Estate Co.) and operated by the next generation of family professionals, grew its practice to encompass both tenant and agency leasing services in the commercial office market in addition to maintaining a strong presence in the loft and industrial markets. The firm was responsible for concluding some of the largest and most significant transactions of the period in New York City.

In the 1960s and 1970s, Williams continued to conclude notable leases in New York. The firm’s principals also added to their real estate holdings, acting as both owner and managing agent. Later, they expanded their activities to include partnerships in the development of two Midtown office properties and ownership in 15 other buildings.

In the decades before the turn of the century, Williams saw further growth of both its services and reach in the New York region. The firm became a founding partner of GVA Worldwide Ltd., a global strategic partnership of leading real estate organizations, and created a new entity, GVA Williams, to act as the third-party brokerage and management division of Williams Real Estate Co Inc. Its affiliation with this network escalated the firm’s client service capabilities to a global level. Closer to home, Williams added Tri-State depth with new offices in New Jersey and Connecticut.

A turning point
In 2008, Toronto-based FirstService Corp. acquired a 65% interest in GVA Williams and the firm was renamed Williams Real Estate, a FirstService Company. For FirstService, the acquisition was a gateway into the New York market. Williams benefited from the greater capabilities of an international platform and new mortgage brokerage, asset management, project management and hotel and hospitality consulting services.

To strengthen their competitive position in the evolving global marketplace, FirstService Williams and other FirstService partner firms committed two years ago to unit under a single brand, Colliers International.

Colliers' New York office has partnered with The Salvation Army for a number of years. In 2017, the firm engaged in several major fundraisers for the organization.

  • In December, Colliers held two fundraisers for The Salvation Army. First, toys and funds valued at more than $1,000 were collected to benefit the organization's Toy Shop Program. In addition, 19 "angels," who are residents of The Salvation Army's Development Disabilities Services program's group homes, received gifts from their personal holiday lists. 
  • A bake sale in October raised money for hurricane relief for the victims of Maria, Harvey and Irma. More than $2,400-worth of cupcakes, cookies and other treats were sold to benefit The Salvation Army's efforts.

Red Nose Day

Through the power of entertainment, Red Nose Day raises awareness and money to help kids in need.
