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 this kind of entrepreneurship and innovation and that has made USIM today’s fastest-growing independent integrated 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 246 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 who believes that you seldom go wrong if you stay client-focused.

Dennis is an advertising industry champion, humanitarian, and philanthropist. He co-founded Ad Relief of Greater Los Angeles, a non-profit organization comprised of industry professionals united to help their colleagues in times of life crisis. This group has distributed more than $2 million to deserving individuals in the Southern California advertising and promotions community. Dennis is a recipient of the Horatio Alger Award, which honors individuals who have succeeded in spite of adversity, and who encourage young people to pursue their dreams through higher education.

As the founder, chairman, and CEO of USIM, Dennis works 12-14 hours a day, seven days a week and still somehow finds the time to call everyone he knows on their birthday. A proud alumnus of the University of Southern California and baseball scholarship recipient, Dennis serves on multiple boards at the University. He is married and has three children, Clayton, Alexis, and Ashley.
