He has been credited with the discovery of the political “soccer-mom” and has been called the “father of the attack ad.” Fortune singled him out as a “new style media master,” GQ Magazine appointed him one 2007’s 50 Most Influential People in D.C., and he was labeled the King of the Republican media consultants by the U.K.’s Daily Telegraph.

Alex Castellanos is one of the Republican Party’s best-known and most successful media consultants and strategists. Castellanos has served as communications consultant to seven U.S Presidential campaigns, has helped elect more than a dozen U.S. Senators and Governors, and enjoys nearly four decades of political consulting experience, both in the United States and abroad. He partnered with Robin Roberts in 1990 to start National Media Inc., a Republican political consulting and public affairs firm.

Today, Castellanos brings a wealth of campaign strategy, public opinion research insights, and communications experience to corporate communications and public policy campaigns. As a co-founder of Purple Strategies, a boutique strategy firm that takes its name from the merger of colors commonly identified with Democrats (blue) and Republicans (red), he’s developed communications strategies and campaigns for some of the world’s most respected companies. He’s also the founder of NewRepublican.org, an organization dedicated to advancing conservative principles into the political campaigns of the communications age.

Castellanos is also an ABC News contributor, has been a member of CNN’s “Best Political Team on Television,” contributes regularly to This Week with George Stephanopoulos, and posts regularly on media outlets, from Político and The Federalist.

A native of Havana, Cuba, Castellanos is fluent in Spanish and English. His parents, refugees who fled Castro’s Cuba in 1961, came to this country with one suitcase, two children and eleven dollars. A Morehead and National Merit Scholar at the University of North Carolina, Castellanos has lectured domestically and internationally, from Harvard University to the United States Army Communication School. Castellanos has also served as fellow at the Harvard Kennedy School of Government.
