Celia has been an integral part of the Pfanner team since 1994. Originally the national advertising director for Racer Communications, Inc., she was charged with managing the advertising department while expanding the client base for RACER and SportsCar magazines. As such, she was primarily responsible for business development and national sales programs. In that role, she also helped develop marketing and advertising projects for clients including Toyota, Honda, Nissan, FedEx, Bridgestone, General Motors, Target, Shell, Motorola, and Mercedes Benz. After Haymarket's acquisition of RCI in January 2001, Celia formed the nucleus of the new marketing services division of the company.

As account director of Pfanner Communications, she is responsible for new business development and supervising projects for clients from the initial sales contact through the delivery of the finished product.
