SYLA Leadership Team
“My vision for SYLA is shaped by living through eight years of war in my childhood and years of leadership research and practice. I believe peace begins with genuine human connection, seeing ourselves in one another, compassionate leadership, and the courage to challenge our own blind spots. As AI advancement and global conflicts reshape our social fabric, we must double down on our commitment to global collaboration. This is the essence of SYLA: to connect leaders and change-makers, bridge cultures, foster collaboration, and promote peace.”
Leila Naderi, PhD , Founder | Co-Chair of SYLA
“For nearly 70 years, the friendship between San Diego and Yokohama has demonstrated what is possible when people invest in one another across borders, cultures, and generations. SYLA represents the next chapter of that remarkable legacy. We are taking the foundation of international friendship and transforming it into a leadership platform that prepares people to solve challenges together, strengthen communities, and build a more peaceful and connected world.”
