About Us

The CSG Story

As is the case with many cleaning companies, the CSG story begins with our founder, Dennis O’Brien, who started out in the industry working as a cleaner. His first small company suffered a devastating blow when he lost his largest customer, and he ended up closing the business.

However, unlike many entrepreneurs who find themselves in that situation, Dennis didn’t give up. He took the lessons he learned from that failure and applied them when he started Cleaning Services Group. Under his leadership, CSG has grown from a small start-up operation to a national organization with over 40 office branches that serve over 1,500 customer sites. However, Dennis has not forgotten his humble beginnings. To this day, he still visits with cleaners on the job site to get their feedback and hear their ideas.
