Mission & Approach

The Overbrook Foundation is a family foundation that supports organizations advancing human rights and conserving the natural environment.


In response to the undeniable catastrophe of climate change and unprecedented threats to American Democracy, human rights and reproductive health in the US and Latin America, The Overbrook Foundation has committed to a mission of supporting organizations advancing human rights and conserving the natural environment.


Since its earliest years, The Overbrook Foundation’s grantmaking approach has been guided by a set of core principles informed by the vision and dedication of its founders and shared by their descendants who serve on the Foundation’s Board today:

Be Bold

Focus on the most pressing challenges in collaboration with the most innovative leaders, and recognize that taking risks can lead to important new solutions.

Be Impactful

Understand what truly constitutes success, and relentlessly ensure that we are supporting our partners in achieving the highest level of impact in our communities and ecosystems.

Be a Partner

The change we seek is far too big for anyone to achieve alone - working in tandem with passionate, brilliant partners is the essential core component of our approach.

Be Accountable

Be accessible and honest, recognizing that transparency and accountability are essential components of ethical philanthropy, and critical to supporting the work of our collaborators and communities.

Be Humble

Always be open, ready to change, and grateful for the privilege to learn from the rich diversity of people and nature that we are fortunate to connect with.

Grantee Voices

UPROSE promotes sustainability and resiliency in Brooklyn's Sunset Park neighborhood through community organizing, education, indigenous and youth leadership development, and cultural/artistic expression.

How did UPROSE as a community organization in Brooklyn end up leading to the development of neighborhood renewable energy sources?

UPROSE has deep roots in the community, and all of our work is designed to address their priorities and concerns. Our success with Sunset Park Solar and the Green Resilient Industrial District and the creation of our Climate Justice Center in 2013 has come in direct response to our community’s request that we take on renewable energy as one of four local climate related priorities.
