GPC Members Gathering

May 7-8, 2024 • New York, United States

Cultivating Trust

Trust is the foundation upon which functioning societies are built. It is the glue that binds individuals, communities, and institutions together, and forms the basis for effective collaboration, cooperation, and the overall well-being of communities. As we navigate an ever-changing world, cultivating trust remains imperative for the health and prosperity of societies worldwide.

Join us this spring to exchange ideas and new perspectives with fellow philanthropy leaders and changemakers on how we can restore trust, (re)-build bridges across the various divides, and encourage the bold thinking, inner work, and radical action required to address the complex and often competing forces confronting the world.

The Annual Members Gathering is the highlight of our events calendar, and we really hope you can take part. This year, it’s going to be bigger than ever as we are hosting the event over two days in the peaceful setting of Stone Barns in Tarrytown, New York.

You might also be interested in joining the learning visit to a local organization prominent in the peace-building space which will take place on May 6, as well as the Spiritual Civilization Gathering on May 9.

We look forward to welcoming you in New York!


The aim of the Annual GPC Members Gathering is to strengthen the bonds and foster meaningful connections within our GPC community by an ongoing weave of inner work, trustful dialogue, and deep listening. We will cover five focus areas: environment, democracy, society, health and technology.

TUESDAY, MAY 7 (10.00 to 17.30)
During the first half of the day, we will spotlight our members’ stories and projects through Insight Talks to inspire the community to think about the way they give, the opportunities available and what could be achieved through respectful collaborations. In the afternoon, following a reflective walk, we will explore the power of collective action through interactive workshops. The day will close with an inspiring keynote presentation.

WEDNESDAY, MAY 8 (10.00 to 17.30)
During the second day, our focus will shift to key themes and trends in philanthropy and civil society. We will explore the opportunities and challenges that technology will bring, especially the use of AI. We will hear perspectives on mental health, conflict resolution, climate action and food justice. We will also explore how the emergence of young donors might affect the current philanthropic norms and narratives. The Annual Members’ Gathering will close with an onsite reception, celebrating our time together.

''Abigail E. Disney advocates for real changes to the way capitalism operates in today's world. As a philanthropist and social activist, she has worked with organizations supporting peacebuilding, gender justice, and systemic cultural change. She is a documentary filmmaker who won an Emmy for “The Armor of Light.” Her latest film, “The American Dream and Other Fairy Tales”, which she co-directed with Kathleen Hughes, made its world premiere at the Sundance Film Festival. The film screened in select theaters and is available on-demand. In Season 4 of the podcast “All Ears,” Abigail used the film as a jumping-off point to ask big-thinking business leaders, union organizers, economists, and others how they would fix our broken economy. She is also Chair and Co-Founder of Level Forward, an ecosystem of storytellers, entrepreneurs, and social change-makers dedicated to balancing artistic vision, social impact, and stakeholder return. She also created the nonprofit Peace is Loud, which uses storytelling to advance social movements and the Daphne Foundation, which supports organizations working for a more equitable, fair and peaceful New York City.

''Peggy Dulany founded Synergos in 1986 to promote trust and collaboration among grassroots groups and government or business leaders and organizations, people who otherwise would not have access to each other, so that they can develop long-term relationships and forge new paths in overcoming poverty. In 2001, she co-founded Synergos’ Global Philanthropists Circle with her father, David Rockefeller, to support philanthropic families in using this approach. Her career has included heading a public high school program for drop-outs and consulting with the United Nations and the Ford Foundation on health care and family planning, and with the National Endowment for the Arts on nonprofit management and planning. She was Senior Vice President of the New York City Partnership, where she headed the Youth Employment, Education, and Community Affairs programs. Peggy is an honor graduate of Radcliffe College and holds a Doctorate in Education from Harvard University. She has sat on over thirty nonprofit and corporate boards including Stone Barns Center for Food and Agriculture, the Rockefeller Brothers Fund, and the Africa-America Institute, among others.
