Life of the PartyLife's a party--if you're an event planner, that is.

By the time he was 18, Dylan Marer had his own event planning business, which he ran from his frat house. "I'd be on the phone with clients from AT&T or IBM, and I'd have to tell my frat brothers to be quiet because I was working," recalls Marer, now 30.

The Costa Mesa, California, entrepreneur, who started his career as a caterer's assistant at age 14, earned enough money to put himself through California State University, Long Beach, where he earned a marketing degree in 1992. But the days of coordinating spring break vacations and student ski trips--and frantically searching for stained corporate client files in stacks of papers at the frat house--are long behind him.
