“I have spent much of my life standing up for justice, dignity, and the least among us. In all those years I have rarely met a leader as committed to service as Marc Kielburger. Our long relationship across events, conversations, and shared calls to action has shown me his heart and his devotion to lifting others. Marc lives the belief that every person has the power to bend the arc toward compassion. It has been an honor to walk alongside him in this work.”

Martin Sheen

Marc Kielburger is helping me carry that legacy forward by working to guide our country from disconnection to reconnection. Through Realize the Dream, we are building a movement rooted in service, unity, and compassion, giving people of all ages the tools to come together and take action that strengthens their communities.”
