Founders and Co-Managing Directors Ray Mayo and Jon Seitz established MayoSeitz Media in 1997 and have grown the agency from its infancy to one of the leading independent media agencies in the United States. This could not have been accomplished without a passionate and talented staff second to none, and a group of blue chip clients who seek leading edge media solutions and have placed their confidence in MayoSeitz Media.
Co-Founder of MayoSeitz Media, Ray was formerly the Media Director of two of the Mid-Atlantic’s largest agencies, Earle Palmer Brown/Philadelphia and GKV in Baltimore. He was responsible for over $100MM of media at each agency and was recognized as the leading media professional in the marketplace by the Philadelphia Ad Club in 1996.
Ray was named as one of the key business and civic leaders under the age of 40 by the Philadelphia Business Journal in their "40 Under 40" listing in March 2002.
