At MacDonald-Miller, we make buildings work better. Period.
We are a full-service, design-build mechanical contractor in the Pacific Northwest. With over 1,000 talented professionals, 11 locations, and our own prefabrication shop, no project is too big or too small. We’ve helped shape the local landscape for over half a century with buildings that operate in the most efficient manner possible. We like to think we’re saving the planet one building at a time.
For us, it’s about culture. The impressions we leave on each other and our clients last for decades. Our clients have trusted us with their buildings for over 50 years. That’s because we listen to what our clients want, and we set out to make it happen.
Collaboration is our foundation and critical to the success of the company. Every team member is valued and brings a diversity of strengths to help us meet our common vision.
“Personally, this value is essential to my role and daily tasks. Working collaboratively as a team in Service Coordination or interdepartmentally is crucial, as it allows us all to provide a prompt, well-informed, and exceptional experience for our customers.”
Karen Neuman, Service Coordination
We actively seek to build relationships and know each other as individuals. Together we create an environment that is welcoming, caring and trusting.
“Community to me is helping co-workers by sharing both your failures and successes to help build a stronger team. I see this in the works every day at MacMiller”
Marco Guizar, Eastside Service Technician
We execute with distinction by doing the right thing and following through on our commitments.
“I believe the culture that MacMiller has created is strongly centered around following through on promises and doing what’s right for our clients and each other. I truly value the dedication and integrity that is at the core of our culture.”
Adam Smith, BPG Estimator
It’s possible to be both serious professionals and good-natured people you enjoy working with. We strive to be both.
“This value has helped me open up as a person over the years. The people I have worked with have been very fun-loving, but they also know how to get the job done (and done right!).”
Chris Schooling, Piping Foreman
Innovation is how we stay an industry leader. We always strive to challenge and better ourselves.
“It’s exciting to work for a company that is constantly on the cutting edge of technology. We challenge the norm of “how we’ve always done it” to find innovative solutions to some of the toughest issues within the Design-Build vertical. That makes my job fun and challenging at the same time.”
Eddie Anderson, Technical Business Analyst
Safety is more than hardhats and boots, it’s an attitude and the environment we create. Every day, everyone goes home to their families.
“Safety is our first priority at MacMiller. There have been a few times our clients have reached out for assistance in the safety arena. Working with our clients really makes it clear how well trained we are and a leader in safety.”
Jeff Pattengale, South Sound Operations Manager
We are committed to building a truly inclusive culture where equitable pathways are paved, and a sense of belonging thrives for all, standing together as one MacDonald-Miller. It is the responsibility of each of us individually to lead the way to real and lasting change.
As a design-build mechanical contractor, we employ a team of world-class engineers who design creative energy-saving solutions to meet or surpass our client’s sustainability goals. Whether a project is in design, under construction, or an existing building ripe for improvements, we have innovative solutions to help customers meet their goals.
