Milestones at Mueller: Our History

Established in 1966, Mueller Associates has a track record of strong leadership and award-winning projects. Throughout our history, we have had only four presidents—all experienced engineers with distinctive academic and professional credentials and a commitment to careful and selective firm growth. Our management places high value on a culture in which talented and dedicated engineers can learn, develop, and perform at the highest possible levels on behalf of our clients.

During our 40+ years in business, we have designed MEP projects for clients through the Northeast and mid-Atlantic. Our work has focused on five primary markets: museums, performance halls, and other cultural buildings; education buildings; healthcare facilities; laboratories; and corporate facilities.
