NAYGN Leading with Impact
Empowering Innovation and Excellence
At NAYGN, leadership is fueled by passion, purpose, and a commitment to our four foundational pillars: professional development, public outreach, networking, and knowledge transfer and retention.
From the Board of Directors to continental committees and more than 150 local chapters, our organization is powered entirely by volunteers. These dedicated individuals collaborate to grow careers, engage communities, share expertise, build lasting connections, and strengthen the nuclear industry—all while giving back and making a meaningful impact.
The Board of Directors, affectionately known as the Core, leads this dynamic network of volunteers. Each board member serves a multi-year term and is elected by NAYGN members.
