Serena Jameka Williams is an American professional tennis player who is ranked No. 1 in women's singles tennis. Williams holds the most major singles, doubles, and mixed doubles titles combined amongst active players, male or female. Williams is regarded by some commentators and sports writers as the greatest female tennis player of all time. In 2008, as part of the Serena Williams Foundation's work, Williams helped to fund the construction of the Serena Williams Secondary School in Matooni, Kenya. The Serena Williams Foundation also provides university scholarships for underprivileged students in the United States. She received a Celebrity Role Model Award from Avon Foundation in 2003 for work in breast cancer. Williams has also been involved in a number of clinics at schools and community centers, particularly those which have programs focusing on at-risk youth. She has also won the "Young Heroes Award" from Big Brothers Big Sisters of Greater L.A. and Inland (2003) and the "Family Circle and Prudential Financial Player Who Makes a Difference Award" (2004). In response to the 2010 Haiti earthquake, Williams, along with other ATP and WTA stars decided to forgo their final day of preparation for the 2010 Australian Open to form a charity event in which all proceeds will go to the Haiti earthquake victims. Serena, along with her sister Venus, is a supporter and contributor of First Serve Miami, a foundation for youth who want to learn tennis but are socially and economically challenged. She has been an International Goodwill Ambassador with UNICEF since 2011 and has helped launch UNICEF's Schools for Asia campaign.
