Gabriel is the co-founder of Authentic Sustainability, co-founder & director of the Byron Fellowship Educational Foundation, a doctoral candidate in Leadership and Sustainability at the Yale Center for Industrial Ecology, and inventor of Human™ Cards.

When Gabriel was a child, his parents went to work each day to contribute toward making the world a better place. He couldn’t wait to grow up and do the same. Over the past fifteen years, he has provided training for more than one thousand purpose-driven leaders and world-class change agents, including social entrepreneurs from six continents and sustainability directors and vice presidents from more than 150 major brands. He envisions a world where people are fully alive, where all life flourishes together through people experiencing their life as a calling, and where people share their whole selves, just as they are, just as they’re not, and as who they want to become.

Today Gabriel’s work supports organizations in creating cultures of purpose, trust, and engagement. He is the CEO of Human Partners and cofounder of the Byron Fellowship Educational Foundation. He holds a bachelor’s degree in physics and a master’s in ecological systems engineering from Purdue University and a master’s in leadership and sustainability from Yale University. His research at Yale explored the relationships between micro-level flourishing of individuals, flourishing organizations and communities, and a flourishing planet. He lives in Seattle with his wife, Sarah, and daughters, Ariana and Madeleine with whom he shares a mission of creating unconditional love and powerfully contributing to others.
