Charlie is a 25-year veteran of Periscope where he was executive creative director. He was also part of the four-person executive team that led the growth of the company to 530 people with offices in four countries. Along the way, he helped hundreds of clients become successful by building long-term relationships, developing trust and using creativity to give brands a distinct advantage. He is also a master of taking the complex and simplifying—or as he likes to say, “How hard can it be?”
