He was promoted to Senior Communications Director in January 2011, and to his current position in August 2012.

From 1997 through 2003, Guenthner was managing editor of The Lone Star Report, a weekly insider newsletter devoted to Texas politics. The Austin American-Statesman said that “Guenthner led a staff known around the Capitol for its extensive knowledge of political and policy details and its passion for the nuances of the legislative process.”

He has appeared on the Fox News Channel's "The O'Reilly Factor" and the Salem Broadcasting Network's nationally syndicated "David Gold Show." He has appeared on local talk programs in many Texas media markets. Channel NewsAsia, an international news channel based in Singapore, used him to explain the aftermath of the 2000 U.S. presidential election. He has been a commentator on Texas issues for NationalReview.com, and quoted in national publications such as The New York Times, The Christian Science Monitor, The Philadelphia Inquirer, The Atlantic Monthly, The National Journal, and The Southern Political Report, as well as daily and weekly newspapers across Texas.

Guenthner has been a leader in the use of new communications technologies in the public policy arena. The Austin American-Statesman selected him as a winner in its 2009 Texas Social Media Awards, which recognize innovation and outstanding achievement by Texans in the field of social media. 

In 1993, Guenthner received his B.A. from Trinity University in San Antonio, Texas, with a double major in political science and speech communication and a minor in economics. He is a past president of Trinity’s Austin alumni chapter and a former state chairman of the Young Conservatives of Texas.
