Optimize Your Workplace©

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

Our approach to providing nationwide coverage is different than our competitors. We have 25 wholly-owned operating companies that employ 10,500 people, covering 46 states, which everyday help American businesses, schools, and government entities keep 300 million square feet clean, cool, calibrated, and safe. While each company is deeply rooted in their hometowns, together we are a coast-to-coast powerhouse, ready to handle any need, big or small. That’s the Mardsen Way.

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 listen to our new Building Intelligence Podcast©, find a library of white papers, and follow our blog. All of it is available at our brand new website at www.marsden.com. And check out our new social media presence!

We are the experts that provide you and your stakeholders a clean, cool, safe, and optimized workplace. The result? Employees and customers who return because they feel healthy, comfortable, and secure.

Gregg McDonald, PresidentGregg McDonald, President

Gregg McDonald’s story is very familiar among senior leadership at Marsden. He started in sales and customer service at one of our operating companies and now leads a major division.

His 30 year career in operations and management helped propel Gregg through our leadership ranks. Starting with our National Maintenance Contractors franchise operation in 2001, he has been a general manager, a regional leader, and today is Marsden Northwest’s president. Our rapid growth in the Northwest would not have been possible without Gregg’s consistent leadership. He has earned the prestigious Registered Building Service Manager designation and is an active member in his local business community.

Today Gregg leads 250 franchise owners and hundreds of employees. Every week Gregg’s team cleans over 750 locations throughout Oregon, Washington, and Idaho, covering over 20,000,000 square feet.

Gregg is a proud Oregonian. In the 1850’s his great-great grandparents arrived via the Oregon Trail and founded and settled in a small town, where Gregg spent his youth. He earned his degree in Business Administration from Oregon State University, where he was a three-year member of the OSU Beaver football program.

Gregg still lives in Oregon, with his wife and two sons.
