It's All about the Experience

UX Planning focusing on the experience, not the channels, to increase engagement and effectiveness.

Our Founder
Dennis Holt
“Dennis is a visionary.
He pioneered a field.”
Bob Humphreys, Chairman of Grey
Advertising Executive Committee

Dennis Holt is one of the advertising industry's true pioneers. He literally invented the idea of unbundling media, creating a $200 billion industry that has become a global business model. It’s that kind of entrepreneurship and innovation that has made USIM today’s leading independent media agency.

Dennis launched Western International Media (now Initiative Media) in 1970 and grew the business into an $11 billion media management company -- the largest in the world. In 2004, Dennis changed the industry once again, founding U.S. International Media. Today, USIM is 190+ media experts strong, entrusted by clients in a wide range of industries, with billings of over $1 billion per year.

Dennis is a fearless entrepreneur, who recognizes that "all business is personal," and believes that you seldom go wrong if you stay client-focused.
