Saunders, who called the new post "crucial" to the firm's future growth, noted Carter has run numerous global accounts, including Visa, and become one of the firm's most decorated client relationship managers.

Current FH Americas chief Jack Modzelewski, a 30-year FH alum, was named global president of business development and partnerships, another new post for the firm.

Saunders joined FH in 2005 and has led its US East, West, Canada and Mexico operations. He also launched its sports marketing unit out of his previous PR career stops with the International Association of Tennis Professionals and NBA's Dallas Mavericks and Detroit Pistons.

Added Saunders: "J.J. is a champion of the FH culture and he is known for his integrity, his creativity and his ability to attract and develop great talent. I am thrilled to see his impact on the firm at the highest level."
