Gregg Weiss was born and raised in Southern California. After graduating from the University of California at Irvine with degrees in economics and social ecology, he made a career in the then-emerging computer industry. Gregg worked his way up to becoming a business executive overseeing sales, marketing and strategy for several Fortune 500 companies both in the U.S. and Australia. Gregg and Rebecca, his wife of more than 30 years, retired while in their 40s and decided to sail the world on their 50-foot boat named Kimba. They anchored in the Lake Worth Lagoon in 2004 and made West Palm Beach their new home.
