Personal life

In 1997, she left the Catholic Church, citing personal reasons. During her career, Graf divided her time between her hometown of Brühl; Boca Raton, Florida; and New York City, where she owned a penthouse in the former Police Headquarters Building in SoHo.

From 1992 to 1999, Graf dated racing driver Michael Bartels. She started dating Andre Agassi after the 1999 French Open, and they married on 22 October 2001, with only their mothers as witnesses. They have two children: a son, born in 2001; and a daughter, born in 2003. Agassi has said that he and Graf are not pushing their children toward becoming tennis players. The Graf-Agassi family resides in Summerlin, a community in the Las Vegas Valley. Graf's mother and her brother also live there.

In 1991, the Steffi Graf Youth Tennis Center in Leipzig was dedicated to her. She is the founder, and chairperson, of "Children for Tomorrow", a non-profit foundation established in 1998 for implementing and developing projects to support children that have been traumatized by war or other crises.

In 2001, Graf indicated that she preferred to be called "Stefanie" instead of "Steffi".
