In 1999, a nervous 17 year-old Andy Roddick was sitting next to Andre Agassi on a flight home from a tennis event. It had been a whirlwind year for the rising star as he began his career as a professional athlete.

Seeking advice, he asked Andre—his boyhood idol—a question that he hoped would provide some insight into his success: "Do you have any regrets?"

Andre quickly responded, "I wish I hadn't waited so long to start my foundation.". Andy took the advice to heart, and at age 17 returned to his home in Florida and immediately set about organizing his first events to benefit children less fortunate than himself.

By age 18, Andy's career was taking off. He won the Australian and US Opens junior Grand slam titles, and was on his way to becoming the No. 1 ranked 18-and-under player in the world. Despite the pressures of his fledging career, Andy continued with his charitable efforts. In 2000, he founded the Andy Roddick Foundation.

Andy's early efforts through his foundation were small scale and limited by his budget and relative anonymity. But these early forays into giving back helped Andy realize his other passion in his life—helping children without the same opportunities that he had growing up.

Then in 2003, at age 20, everything began changing. He won the first two of his five Masters Series titles in Montreal and Cincinnati and then shook the tennis world by winning the US Open. Propelled by his professional success, an all-volunteer Foundation raised more than $11 million to fund programs that enhance educational and economic opportunities for thousands of children throughout the United States.

Now upon his retirement, Andy is focusing his energy on the foundation in Austin, Texas.
