Muller Engineering Company (Muller) was awarded a 2025 Top Workplaces honor by The Denver Post and ranks as the 24th Colorado Top Workplaces on the list (up from #30 in 2024). This is the eighth year Muller has received the award.
“We’re grateful to be recognized as a Top Workplace for the seventh year,” said Muller President A. Gray Clark. “This recognition means a great deal to us because it comes from our employees. By listening to and engaging with the entire Muller team, we continue working to make Muller a place where people feel valued and supported—now and moving forward.“

The Denver Post partners with Energage Inc., a third-party employee engagement firm, to conduct an anonymous survey of employees from small, medium, and large businesses in the Denver area. The companies named are recognized based solely on employee feedback about workplace culture, including leadership, values, direction, communication, and benefits.
