Green Team Academy is a nonprofit based in Denver, Colorado. We are a fiscally sponsored project of Social Good Fund, a California nonprofit corporation and registered 501(c)(3) organization, Tax ID (EIN) 46-1323531. 

Our Mission

We empower everyday people to #BeTheChange. 

We help people get together, make a difference, and feel better by starting and growing thriving green teams in their communities. We bring people together across the world to collaborate and create a more just and verdant world.

Our Vision

Green Team Academy is working to become the global leader in mentoring and mobilizing communities. 

Our Values

We believe that every person is an expert in their own community. With a little bit of support and guidance, they can take their ideas for improvements and make them a reality.

We see people around the world stepping up to become grassroots leaders, quickly getting environmental and community initiatives off the ground and making a positive impact.

We believe that we can transform our world by offering individuals an opportunity to transform themselves and their communities. 

We believe in making extra efforts to reach out to those who have been impacted most by environmental and economic inequities. We know that when we develop relationships with people in our communities and across the world, we all benefit.  

Our Team

Meet the team that's helping make the magic happen! As a new nonprofit, we are starting with an Interim Board of Advisors and a Community Advisory Board. We are excited to be creating an inclusive board with youth and a diverse group of people from around the world. Interested in joining our team? Apply here!
