Like a small, local company, the regional offices make decisions on all aspects of their service operations and are empowered to manage their teams and respond to all client needs and requests.

Guy Mingo

We know that running a successful organization is hard work. We also know that maintaining the day-to–day appearance of your facilities should not keep you from focusing on your core business. Yet, keeping a clean, safe and comfortable environment has a direct impact on your employees and clients. So, our job is to do the hard work getting your workplace clean, cool, calibrated, and secure for tomorrow.

All Marsden companies are heavily invested in their communities – from CleanPower in Milwaukee to Haynes Building Services in San Diego; and from American Security in St. Paul to Sunstate Mechanical in Phoenix. Our way is different. We stay invested in these communities, which allow us to know our customers quite a bit better.

Our founder Skip Marsden was driven by a simple mantra: go where the customer wants to go. This vision led us to expand from our original mission. Today we not only clean, but we keep buildings comfortable, keep them fine-tuned, and keep them safe.

If you are our client, thank you. If not, find out why we clean and secure over 3,000,000 square feet every day, for hundreds of clients, from coast to coast. What more can we do for you?”

— Guy Mingo, CEO, Marsden Services


Marsden West is woven into the community at all levels, we are committed to giving back to the community and actively seek opportunities where our clients and employees live and work. When people work together great things happen.
