What can be done about our most persistent public health challenges? Mental health, in particular, has eluded simple solutions for decades, made more complex by forces that feel increasingly beyond our control.
In recent years, uncertainty has intensified. Global instability, economic strain, and shifting policies have left many communities unsettled or left behind. Simultaneously, trust in institutions and information including science, media, even what we see and read, has eroded. It is not a good combination, and it has real consequences for mental health.
Public health has responded with urgency. There are growing calls for stronger national policies and expanded access to care. Integrating mental health into primary care, for example, has helped many, though not everyone. Too often, solutions depend on individuals seeking and receiving care, having access to resources, or being insured. And even when care is available, clinical approaches alone cannot resolve what are, at their core, social and structural challenges.
Where does that leave us?
I find myself returning to a simpler, but no less powerful, idea: mental health is shaped by the environments we create. It is influenced by whether people feel connected or isolated, supported or overlooked, trusted or dismissed.
We are living in a time that often pulls people apart—remote work, digital spaces, and social media can deepen isolation rather than connection. It has been called a loneliness epidemic, and it raises an important question: how do large-scale solutions take hold in a society that struggles with basic connection?
Part of the answer lies closer to home than we might think.
I believe we can begin by rebuilding what holds us together, what some have called the “social fabric.” This is not about sweeping changes. It is about small, consistent actions that build trust over time: how we show up, how we listen, how we treat one another. These moments may seem minor, but they accumulate, and they matter.
I see both the strain and the opportunity in my own community. Among colleagues, students, friends, and family, there is a level of anxiousness, but also a desire to reconnect and move forward. That is why culture matters. It is not abstract; it is lived experience.
At the Colorado School of Public Health, I think often about the kind of environment we are creating. A place where people come together, where relationships are formed, where trust is built. Sometimes it looks like serious work and shared purpose. Other times, it looks like laughter in the hallway or someone bringing in baked goods. These moments are not incidental; they are foundational.
Because what happens in our workplaces and classrooms does not stay there. If people leave feeling supported, valued, and connected, they carry that with them—into their homes, communities, and broader networks. That is how small pockets of stability begin to ripple outward.
Public health has always been a stabilizing force in society. In this moment, in particular, our role is evolving. It is not enough to rely on authority or expertise. We must also build credibility through relationships, through proximity, and through trust—one person and one community at a time.
Trust is shaped not only by what we do, but by how we do it. It is built in everyday interactions: how decisions are communicated, how uncertainty is acknowledged, how people are treated along the way. Culture is not separate from outcomes—it drives them.
If we want to improve mental health at a population level, we must pay attention to these foundations.
Cycling season came early this year, and I took advantage of the unseasonably warm weather this past weekend and went out for a ride. As I climbed the first hill I encountered, I am reminded that progress—on a bike or in public health—rarely happens all at once. It is built through steady effort, persistence, and those at our side.
Here is the opportunity before us: Start where you are. Strengthen the culture around you. Invest in trust: in your teams, your classrooms, your communities. The effects may seem small in the moment, but they are not. They are the beginning of something larger.
