The NDN Collective


We must continue to Defend our people, communities and nations against negative resource extraction that poison our people, pollutes our water, destroys our land, contributes to climate change and violates the rights of our people. Doing this through organizing our communities, making our voice heard and utilizing a wide variety of tactics is imperative in shifting the political and financial systems that are impacting our communities.


We must continue to develop Indigenous communities in a regenerative and sustainable manner based on our values and connection to land, culture and identity. We need to meet the needs of the present generation without compromising the ability of future generations to meet their own needs. We are doing this through regenerative community development, renewable energy investments and social enterprise development.


We must continue to decolonize our minds, communities and sovereign nations. The decolonization of our communities and people is directly related to our ability to prosper. Through the revitalization of our Indigenous ceremonies, culture, languages and life ways we will continue to strengthen our identity, and break free from the oppressive systems that disconnect us from achieving the healing, growth and connection to spirit that is integral for us as Indigenous people.

In 2018 the NDN Collective will be introducing and launching a set of related entities that will be a tool box of opportunity for Indigenous communities to defend, develop, decolonize and achieve their goals. NDN will do this through increasing philanthropic investments, social impact investments, creating political momentum and building the capacity of Indigenous communities. Please stay tuned in 2018 for future developments as we roll out this comprehensive and multifaceted approach to building community based power in Indian Country.
