In 2003, GCA Services Group, Inc. was founded by a group of entrepreneurs and private equity firms with the vision of becoming the premier national provider of facility services in the United States.


To effectuate this plan, GCA promptly went shopping for the companies that would become GCA Services Group. The plan was to acquire several well-respected regional companies and leverage the strengths of each to create a national facility services company superior to all others in the industry. The companies were identified, acquired, and integrated—and GCA Services Group was launched, with the mission of providing its customers with unmatched quality and value through superior services—measured, managed, and guaranteed.
