Our Roots

Our story begins with our founder, Dennis O’Brien, who started out in the industry working hard as a cleaner. He founded his first small company but suffered a devastating blow when he lost his largest customer and ended up closing the business. However, this did not stop Dennis as his belief and entrepreneurial personality drove him to form Cleaning Services Group, applying every lesson he learned previously. Under his leadership, CSG has grown from a small start-up operation to a national organization with representation in over 40 states. He built CSG by putting the best people, products and systems in place to ensure that the customer is satisfied, every time.
