Gilles Houde to retire after 35 years with GNC

Gilles Houde, the Canadian president and general manager of GNC, has announced his retirement from the company. After 35 years of work with GNC, Houde’s last day will take place on Friday, August 18.


At this time, John Castiglione will take over as GNC’s new general manager. Until then, Houde is working to ensure a smooth transitional process.
Gilles began his work with the retailer in 1982, operating out of the store’s Montreal office. Since that time, he has also worked for locations in South Carolina, Oregon, England, ultimately returning to his native location 16 years ago.
“GNC has been good to me and continues to do so,” Houde said in an email statement. “I will forever be grateful to GNC and the many colleagues I worked with inside and outside of GNC.”
