Shriver was born July 20, 1965 in Boston, Massachusetts to Eunice Kennedy Shriver and Sargent Shriver, Jr. His mother is the founder of Special Olympics and his father is a founding director of the Peace Corps. Through his mother, he is a nephew of World War II casualty Joseph P. Kennedy, Jr., President John F. Kennedy, Senator Robert F. Kennedy, Kathleen Kennedy Cavendish, and Senator Ted Kennedy. Anthony Shriver is the youngest of five children.
He graduated from the Georgetown Preparatory School, North Bethesda, Maryland; he then attended Brown University before transferring to Georgetown University in Washington, D.C., from which he graduated in 1988 with a double major in theology and history.
Shriver is the founder and chairman of Best Buddies International a nonprofit 501(c)(3) organization which he created in 1989. Best Buddies is a nonprofit organization that provides adults and children with intellectual and developmental disabilities social inclusion and job opportunities. He has been able to get the organization to spread throughout the world and it has over 1500 chapters today. Shriver spoke in 2008 about the all-inclusive nature of the program: "The great thing about Best Buddies is there’s something for everybody. You can be a volunteer in some shape, form or fashion, whether you’re volunteering to get your kids involved, whether your son or daughter is involved in their school program, whether you want to be a mentor yourself as an adult, whether you want to get an online Buddy, whether you’re an employer and want to hire someone with a disability to work in your office—if you’ve got any sense of motivation and determination and want to give back, there’s a role for you at Best Buddies, which I think is pretty unique. Even in Special Olympics, for most people, you can be a coach or a spectator, but you’re not going to run the 50-yard dash. In Best Buddies, you’re running the 50-yard dash with your Buddy. People get a different level of experience by participating, as opposed to writing a check, though that’s important, too. But beyond writing checks, we need people to get involved and give their time."
Best Buddies has grown into a leading nonprofit entity with increasing international reach across six continents; establishing a global volunteer movement that creates opportunities for one-to-one friendships, integrated employment and leadership development for people with intellectual and developmental disabilities.
In addition, Anthony and his brother Timothy (the chairman of the Special Olympics) have recently aligned Best Buddies and the Special Olympics to create the Eunice Kennedy Shriver Challenge event, aimed to encourage greater acceptance and inclusion for those with intellectual and developmental disabilities. Shriver has also been a director of UniCapital Corp. since March 1998. UniCapital Corp. is an investment house.
