Today is World Mental Health Day. 🧠💚In a world where work can sometimes feel isolating or overwhelming, community and connection can make a difference. Having people around us to share an idea with, grab coffee with, ask for help, or simply say hello can help us feel more connected to our mission and to one another.
For more than 20 years, The Alliance Center has been a shared work and gathering space for people working on climate, sustainability, and community issues. Our coworking days, cafecito coffee hours, and partner events lower the barrier to the casual, in-person connections that public health researchers increasingly link to measurable gains in wellbeing. The standing coworking dates, no-agenda team meetings, and self-declared downtown days are exactly the kind of gatherings our model was created to support.

"Now more than ever people need community and places for people to gather in community," said a tenant in response to a survey. "The Alliance Center is that place where those concerned about environmental protection, advancing sustainability, mitigating climate change, defending democracy and so much more can develop strategy and make plans to work together."

For this World Mental Health Day we encourage you to invent your own version of these rituals—a standing coworking date, a weekly team day, a downtown day—to rebuild a habit of in-person gathering in the face of our automated future.

The Alliance Center is more than a building. It’s the people who make it a community.

From The Alliance Center staff who help create a welcoming, connected space to the mission-driven organizations and people who call it home, our community is made up of individuals working to make the planet a better place.

Our tenant community brings together nonprofits, businesses, and organizations focused on climate, sustainability, and justice. That diversity is part of what makes the Alliance Center special. It creates opportunities to meet someone new, share an idea, find a collaborator, or simply feel a little more connected to the work you’re doing.

While our tenants may each have their own mission, they’re part of something bigger when they’re here.

Join us in celebrating the people who make the Alliance Center what it is—today and every day.

Meet the staff and tenant community behind the Alliance Center. 👋

Before it was The Alliance Center, 1536 Wynkoop, built in 1908, was a six-story warehouse for dry goods, arriving or departing by train at Union Station. Over the decades, the building served as a warehouse, housed the Tattered Cover’s operations, and was even home to the first official offices of Wynkoop Brewing Company.

Our chapter begins in the late 1990s. In 1997, seed funding from John Powers helped launch the Colorado Environmental Coalition and the Alliance for Sustainable Colorado. The vision was to create a home for like-minded organizations—and a place where they could work together, share ideas, and foster collaboration.

That vision grew. By 2004, the Alliance for Sustainable Colorado had been formally established, and the Alliance Center had become a home to dozens of environmental and social justice organizations, while also providing space for events and programs that brought people and ideas together.

More than 20 years later, that spirit is still at the heart of The Alliance Center.
The building has evolved. The community has grown. And our collective work has expanded. But the idea that we can accomplish more when we come together remains.

As we look at The Alliance Center’s past, present, and future, we’re taking a moment to remember where this community came from—and the vision that continues to move it forward.

Where we’re going starts with why we’re here.

For more than two decades, The Alliance Center has brought mission-driven people and organizations together to connect and collaborate for our planet. While our community, spaces, and work continue to evolve, our purpose remains rooted in the belief that we can accomplish more when we work together.
We’re celebrating The Alliance Center’s past, present, and future this month, and we’re starting with the foundation that guides us: our mission and vision.

Over the coming weeks, we’ll be sharing the people, organizations, ideas, and moments that have shaped The Alliance Center—and explore what’s ahead.
Alison Carlman, our Executive Director, wrote why we’re sharing more about who we are and where we’re going. https://linktr.ee/thealliance.center
