History
| COMPANY HISTORY |
GSF Corporate Building Systems (CBS) and Maintenance Engineering Inc (MEI) were founded over twenty five years ago with the belief that commercial cleaning services could be raised to a level of quality never before seen in the industry. CBS and MEI were acquired by Group Services France (GSF) in April, 2005, as a wholly-owned subsidiary. GSF was then, and continues to be today, a privately owned and operated entity. Recently being acquired by GSF has given CBS/ MEI the opportunity to partner with a 500 million dollar company with tremendous resources. Today GSF company’s CBS and MEI employ over 500 Associates from their base of operations located in Buffalo Grove Illinois.
GSF takes Pride in offering a wide range of services, products and solutions to enhance the success of our clients. We accept the challenge of continued improvement and remain committed to exceeding the expectations of each and every client—each and every day.
