Mission Statement

The Alliance Center brings people together to create a world where our communities are inclusive, our democracy is strong, our economy thrives and our planet is healthy.

Organization History

The Alliance Center received 501(c)(3) status from the IRS in June 2004. Later that year, the organization purchased a 100-year old warehouse building and adjacent empty lot in Denver's historic Lower Downtown (LoDo) district and created the Alliance Center, Denver's multi-tenant nonprofit center for organizations working on sustainability issues. The Alliance Center was renovated "Green," becoming the first historic building in the country to earn two Leadership in Energy & Environmental Design (LEED) certifications, one for Existing Building (Gold) and the other for Commercial Interiors (Silver). It now provides offices, meeting space and shared services to a community of nonprofit tenants. The building creates synergies and fosters partnerships that accelerate progress on issues that affect the Triple Bottom Line, ensuring consideration of impacts on Colorado's people, environment, and economy.

The Alliance Center has proven to be an award winning facility and a leader in sustainability design, receiving various awards for contributions not only to High Performance Buildings but also in the field of education. To date, The Alliance Center has been the recipient of numerous prestigious awards and continues to advance as a model for sustainable commercial structures.


"The Alliance Center is the place where Colorado's sustainability leaders come to deepen their impact. With a cutting edge building, a powerful network, and mobilizing impact programs, The Alliance Center drives solutions to create a better future for Colorado. The Alliance Center inspires me to continually push the limits and drive systems change." - Former Governor Bill Ritter
