I've had the good fortune of knowing Dennis since he became the Allstate spokesman in 2003 (my wife, Lisa, is in charge of integrated communications for Allstate--including advertising). Prior to that time, I only knew Dennis as President Palmer on "24."
Dennis is also a long-time supporter, Clean Water Ambassador and Honorary Board member of RainCatcher, an organization that delivers clean water solutions to impoverished regions in Africa and around the world. Check out their website at raincatcher.org and lend your support, too. Water is life.
