Few executive teams in the industry can compete with the Collins Building Services record of success and longevity.


Working together over multiple decades to build the firm, Collins’ management and executive team draws on more than 300 combined years of experience—years that often included working their way to the top from on-site cleaning positions.


They have devoted their lives to the business, built the firm into one of New York’s largest building services companies, and through their combined expertise and cohesive teamwork, are continuing to develop the next generation of Collins leadership.

About Us


In October 1988, when the building services industry was emphasizing bigger is better and mergers and consolidations typified the market, Joseph Collins bucked the trend. He believed the time was right for a service-driven firm delivering personal care and attention at every level. He founded that firm, put his name on it to underscore his unflinching commitment to the highest quality of service, and assembled a team of like-minded executives. Together, they took this message to potential clients.


Collins Building Services, Inc., became known as the company where leadership was personally involved and on site, fielding service teams who took ownership of their responsibilities.

Turnover was and is well below industry average; promotion from within ensures supervisors have in-depth knowledge of the job at hand and they, in turn, have groomed a loyal staff. Collins went on to develop proprietary quality control and training programs, and committed itself to meeting client needs in advance, pioneering GreenSafe, its environmentally responsible cleaning program; a customized, web-based Facilities Management Program (FacMan).


Today Collins is one of the largest building service firms in

New York, serving many of the City’s premier owners, managers, corporations and institutions. With 2,800 employees and in
excess of 100 million square feet under contract, its founding
vision is more important than ever: deliver personal service
of the highest quality, every day—a value that will outlast and outperform any market trend.

Executive Leadership


Joseph K. Collins, President

The driving force behind the founding of Collins Building Services, which he created as his ideal service organization, Joe Collins works to maintain those ideals every day as the President of the firm. In all his roles—from leader of one of New York’s largest building service firms, to employee mentor and client service executive—he stands on his 50-year reputation of delivering nothing less than the highest quality work and personal service, learned from the ground up. It is that level of accomplishment that earned him a Finalist position as Entrepreneur of the Year in a
NY-based magazine competition shortly after founding the firm.


Joe Collins may have begun as a package clerk with a cleaning corporation for a major residential complex, but his name today is synonymous with leadership and service excellence at all levels throughout the building industry.
