Stan was born in Switzerland to a Swiss mother and a German father, giving him dual Swiss-German citizenship. His father, Wolfram Wawrinka, is a farmer and social worker of Czech descent. Isabelle Wawrinka, his mother, is a teacher. She also works with people with disabilities as a biodynamic farmer. Later, the pair bought “Ferme du Château,” a farm near Lausanne originally run by Wolfram’s parents.
They also cared for mentally ill people, allowing them to live independently and work on the family farm. Stan was raised on a farm by parents who did not appreciate sports, but this did not stop him from following his dream of being a professional tennis player. Stan and his brother would play tennis at the local tennis club. Furthermore, the pro tennis player appreciates his parents’ efforts to provide for him and his siblings.
