Nuzzo joined GNC in 2008, and will remain with the company until at least July 18, 2014. GNC has already started a search for his replacement.
"Following a great run of more than five years as GNC's CFO, I was presented with a unique career opportunity that will challenge me in new and different ways,” said Nuzzo. “I look forward to this new chapter in my career, and am confident the longevity and financial strength demonstrated by the GNC business model will enable it to attract another successful CFO."
GNC chairman, president & CEO Joe Fortunato credited Nuzzo as being instrumental in leading GNC through a number of growth initiatives, building the foundation for its transition to a public company, and instituting a disciplined capital structure.
