We're a Marsden Company!

What does it mean to be a Marsden company? Well, it means that we are part of one of America’s largest privately-held commercial cleaning and security firms. Supporting 25 distinct brands under one umbrella is unique in our industry. But we think it is a better way to serve our thousands of clients.

National Scope

We have five regional headquarters throughout the United States. Our Central Region with several firms services over 300,000,000 square feet with over 1000 employees and managers who live in the communities we serve.

Local Dedication

We self-perform an astonishing 97% of our business. When we bring new companies into our family we keep their local offices and maintain human resources and recruiting in the community, which allows us to invest in our clients – by really being there. We believe our clients want the hometown team, but also want deep and meaningful support from a sophisticated partner.

Great Resources

One of the benefits of being a part of a firm like Marsden is that we can share resources from all of companies, producing exciting new content. You can find a library of white papers, and follow our blog. All of it is available at our brand new website at And check out our new social media presence!
