Mark Danner – Jefferson County, Colorado

In his first days at Jefferson County, Mark Danner wasn’t sitting behind a desk. He scrubbed toilets at a nature center, hauled trash and did every piece of janitorial work the job required. More than four decades later, he still keeps that memory close, not as a hardship but as a foundation. It taught him that no task is beneath a good leader, and that lesson has guided every step of his career since.

Danner now serves as director of facilities management for Jefferson County, a role he has held since 2013 after joining the county in 1983 as a resident caretaker of a nature center and later becoming the operations supervisor for parks and open space. Jefferson County, headquartered in Golden, Colorado, has grown into a vibrant suburban, business, industrial and recreational community since its formal organization by the Colorado Territorial Legislature in 1861, and it now depends on safe, reliable and efficient public facilities to serve its residents every day.

Danner’s team is responsible for that mission, overseeing 56 buildings totaling approximately 1.75 million square feet, sprawled out over 40 campuses, with duties that range from daily custodial work to managing building systems, providing physical security and grounds maintenance, including but not limited to capital improvement projects worth tens of millions of dollars.

Building a career rooted in service

Danner grew up in a large farming family in Iowa where hands-on work and long hours were simply part of life. That upbringing shaped his early approach to teamwork and public service, and it followed him west when he and his fiancée, Gretchen, now his wife of 43 years, moved to Colorado the same weekend they finished college in Northern Iowa. He started at the bottom of the organization and worked his way through nearly every corner of it, from parks and open space to fairgrounds management to full facilities management leadership.

“No matter what role you’re in, you do it to the best of your ability,” says Danner.

That mindset became a personal standard he has carried through every position since, and it remains central to how he evaluates the people around him today. He often refers to a document he has shared with staff for years outlining professionalism across every role in the department, from cleaning and mail delivery to the trades and executive leadership. In his view, every position matters equally, and if one link in that chain breaks, everyone feels it.

Leading through culture, not just construction

Danner is quick to point out that his personal expertise was never in hands-on construction or engineering. Instead, he has built his career around leadership and culture, which he considers the true driver of a high-functioning team. That philosophy has produced a team whose leadership members average 25 to 30 years of service, a rare figure in facilities management and one that provides deep institutional knowledge alongside a steady appetite for improvement.

“Seventy percent of my role, or any good leader’s role, is to develop culture in the organization,” says Danner.

He describes hiring as an evolving process that now starts with character rather than a resume alone. While technical skills and experience remain essential, Danner wants people who fit the department’s values first, trusting that the right expertise needs to be paired with the right person. That approach reflects his broader belief that facilities management is fundamentally a service business, one where internal culture directly shapes the experience external customers receive.

“We are providing a service, and we want our customers to know they can depend on us day in and day out,” says Danner.

Central to that culture is a belief that employees are people first and professionals second. Danner encourages his team to protect their personal lives with the same seriousness they bring to their work, reminding them that fulfillment outside the office matters just as much as performance inside it.

“No matter how much you love what you do, when you leave the office at the end of the day, that is when your life begins,” he says.

Modernizing a growing county

Technology has reshaped facilities management dramatically during Danner’s tenure, moving the department from paperwork orders to sophisticated computerized maintenance systems capable of tracking assets and managing mobility across dozens of buildings. Building automation has advanced significantly as well, giving his team greater visibility and control over aging infrastructure that still requires constant attention.

Among the department’s most visible recent achievements is a multi-million-dollar renovation of a portion of the county’s flagship administrative and courts facility, a nearly 500,000-square-foot building that anchors much of the county’s operations. The project reimagined traditional office space into a flexible, collaborative environment built for hybrid work. That renovation, nicknamed “Base Camp” via an internal County employee naming survey, has become a point of pride for Danner and his team, who worked closely with vendors and contractors to keep the project moving without disrupting daily operations.

The flagship renovation is only one piece of a broader facilities master plan that Danner’s team is updating to guide the county’s space and growth needs for the next 15 to 20 years. The process has required a close examination of nearly every county department’s needs, conducted alongside outside consultants, as the organization adapts to lasting shifts in how public employees work following the pandemic. Danner’s team is also moving forward with security enhancements to the flagship building rotunda modeled after the home of the County’s namesake, Thomas Jefferson.

Developing the leaders who come next

As the department has modernized, Danner has placed increasing emphasis on preparing the people who will carry that culture forward. Over the past year, he has intentionally accelerated mentorship for a group of assistant directors he considers exceptionally capable, giving them broader exposure to strategic decision-making and future planning.

“You’re always interviewing for your next job, and people are always watching you whether you’re noticing it or not,” says Danner.

He credits his own growth to closely observing both strong and difficult leaders earlier in his career, learning as much from what not to do as from what worked. That awareness now informs how he mentors others, encouraging consistency, humility and genuine care for people as the qualities that separate good leaders from great ones. Away from the office, Danner applies that same discipline as a competitive cornhole player, where he says steady, repeatable execution matters just as much as it does at work.

For Danner, the measure of his leadership has never been about a single project or building, but about the people who will carry the department’s culture into its next chapter. He is candid that he does not know exactly what the department’s future leadership structure will look like, but he trusts the foundation his team has built together to guide that transition when the time comes.

That trust extends to the vendors and contractors his team relies on for major projects like the flagship renovation, a partnership Danner is careful never to take for granted. It is a small detail, but one that reflects the same philosophy that has guided his entire career: treat people well, stay consistent, and the results will follow. As Jefferson County continues to grow, that approach, more than any single building or budget, is what Danner hopes will define his legacy, ensuring that the values he has spent more than four decades building remain firmly in place for whoever leads next.
