60 Years of Invisible Excellence

For 60 years, Mueller Associates has worked behind the scenes to help extraordinary buildings—and the people and institutions within them—perform at their best.

Founded in Baltimore in 1966, Mueller has grown from a four-person engineering practice into a nationally recognized firm serving museums, universities, performing arts organizations, cultural institutions, and other mission-driven clients.

As we celebrate our 60th anniversary, we’re honoring the people, projects, relationships, and ideas that shaped Mueller—and looking ahead to the next chapter.
