For over twenty-five years, LeaderSpring has invested in the extraordinary talent, dedication, and vision of progressive leaders. The National Committee for Responsive Philanthropy has recognized LeaderSpring as one of four pioneering leadership development programs in the United States.

LeaderSpring undertakes its work by delving deeply into what impacts and undermines leadership among people of color in the social sector and other marginalized groups, honing-in on systems of oppression. These systems not only assail low-income and historically marginalized populations, but they also impact the leadership of those committed to transforming communities.

LeaderSpring resolves to be a catalyst for societal good by facilitating:
-Transformative processes that elevates people’s agency, collectively and individually to optimize leadership for change; and
-Changes in organizational culture and structure in efforts to oppose and dismantle systems of oppression.

The mission of The Leakey Foundation is to increase scientific knowledge, education, and public understanding of human origins, evolution, behavior, and survival.

The Leakey Foundation is a 501(c)(3) nonprofit dedicated to funding scientific research that explores the many facets of human origins and sharing the results of this research through our innovative educational programs.

We are based in San Francisco, California, and we are the only U.S. funding organization wholly committed to human origins research and education throughout the world.

The Leakey Foundation promotes a multidisciplinary approach to exploring human origins. We award more than $800,000 annually in field and laboratory grants for vital new research and long-term projects. We give special encouragement to early career scientists asking new questions and seeking innovative ways to answer these questions about human evolution. Like venture capitalists, The Leakey Foundation understands that the greatest rewards come from taking the greatest risks.

Our mission is to improve outcomes for women and children in Louisiana, by advocating for all people to have the resources, information, rights, and ability to make their own decisions about their sexual healthcare needs and to access healthcare services.

Lift Louisiana believes in elevating and amplifying the voices of people, community leaders, and experts to change the policies behind the poor health outcomes for women in our state.

Lift Louisiana educates and trains people to discover their voices and to effectively use them to hold public officials accountable. We’re reaching into communities whose voices are not being heard and building a diverse statewide network of advocates – joining voices together to make them stronger and more powerful.

When policies create barriers to women’s healthcare, we have a team of lawyers that advocate for us in court.

Listen4Good (L4G) is a pioneering capacity-building program that promotes high-quality listening and equity-driven feedback practices across the social sector.
While many organizations want to hear from those they serve so they can make sure their services are meeting clients’ needs in as effective and equitable a way as possible, they often lack effective tools to support their efforts. L4G takes the guesswork out of this process for organizations and provides an easy to follow roadmap for building a strong feedback practice.
By joining our community of giving, you are helping us to better serve organizations, and to make listening and feedback – anchored by strong equity principles – a norm within the sector.
Check out our feedback stories to learn more about the impact of our work.

We expand protected areas, support ecological research, and empower the public to become stewards and advocates for the natural world.

Birds are amongst the most easily appreciated organisms in nature, and they are also excellent indicators of ecosystem health.

Inspire … then educate.

The Center creates and oversees national science education programs with a focus on Earth and space. Programs are designed to provide an authentic window on science as a human endeavor, and recognize that scientists and engineers can and should be heroes and role models to our children. The Center’s mission is to help ensure a science literate public and a next generation of scientists and engineers—both of which are of national strategic importance in an age of high technology.

A diverse array of programs for schools, families, and the public; professional development workshops and institutes for grade K-12 educators; world-class exhibitions for museums, science centers, and universities; and online and Web 2.0 experiences, embrace the notion that science education should be about conceptual understanding at an emotional level.

The Center embraces a Learning Community Model for science education where the Center’s programs for diverse audiences can be combined to engage an entire community. Programming is designed to be sustainable; tailored to the strategic education needs of the community; and delivered systemically across school districts.

The Center’s partners include the Smithsonian Institution, NASA, the Carnegie Institution of Washington, the John Hopkins University Applied Physics Laboratory, the American Association for the Advancement of Science, the Arthur C. Clarke Foundation, and at the local level: museums, science centers, and school districts.
